What is the side voltage of a lithium battery? How to control side voltage!
The side voltage of the lithium battery refers to the voltage of the aluminum layer between the positive ear of the soft-pack battery and the aluminum-plastic film.In theory, the aluminum layer between the positive electrode and the aluminum-plastic film is insulated, that is, their voltage should be 0In fact, during the processing of the aluminum-plastic film, the PP layer of the inner layer will be locally damaged, resulting in local conduction (including electronic channels and ion channels) between them, forming a microbattery, and thus a potential difference (voltage).The side voltage standard varies from manufacturer to manufacturer, but most of the industry is set below 1.0V, and the standard voltage is based on the dissolution potential of aluminum lithium alloy!Why control the side voltage?Because if the inner PP film of the aluminum-plastic film is damaged, the capacity will be corroded.The conditions for corrosion must have two points: 1, the electronic path, the negative electrode and the aluminum layer of the aluminum-plastic film form the electronic path; 2, the ion path, the aluminum layer of the aluminum-plastic film and the electrolyte form an ion path; Without either one, corrosion doesn't work.After the two conditions are established, the lithium ion will react with the aluminum layer of the aluminum-plastic film to generate lithium aluminum alloy; Lithium aluminum alloy is a powdery substance, resulting in aluminum-plastic film penetration; That is, we often see some black spots inside the aluminum-plastic film; These dark spots will become more and more obvious with time and the number of charges and discharges.How to choose?The current statistical detection methods are:1, test the resistance between the aluminum plastic film and the negative ear, greater than 5M ohms is relatively safe, some companies define the relatively low, look at the final PPm of bad products we endure, you can measure some data and then define their own standards can also; This resistance test is mainly to pick out the electronic path;2, test the current between the positive electrode and the aluminum film, you can use the DC source test, it is generally believed that the current is greater than 0.001mA, it is defective, need to be picked out;3. Test the voltage between the positive electrode and the aluminum film, which is generally considered to be greater than 1V for defective products.You can test 1 and 2, or 1 and 3 together.

Prelithium technology of lithium ion battery
Prelithium technology of lithium ion battery
Lithium-ion battery (LIBs) has become one of the widely used electrochemical energy storage systems due to its high energy density, high operating voltage and no memory effect, and its commonly used graphite negative electrode is difficult to fully meet the increasing market demand due to its relatively low capacity (372 mAh g-1). Over the past few decades, researchers have proposed a variety of new anode materials, which generally exhibit the advantages of ideal potential range, higher capacity, excellent magnification performance, and long cycle life, but have the disadvantage of large initial active lithium loss (ALL). Therefore, how to eliminate ALL before full battery assembly is critical to achieving high-performance LIBs. In the course of development in recent years, new anode materials for the next generation of LIBs have gradually begun to be commercialized, so the research of pre-lithium technology, which is crucial to the elimination of ALL, has become an important research direction.Causes of loss of high initial active lithium in negative electrodeThe high initial ALL of the negative electrode occurs in the first few cycles and the coulomb efficiency is low (CE < 100%), which indicates that some Li+ remains in the negative electrode, resulting in a decrease in the amount of Li+ that can be cycled in the LIBs. When matched with the positive electrode, the reduced recyclable Li+ will inevitably lead to a reduction in the energy density of the entire battery. Figure 1 shows the typical intercalation/insertion, conversion and alloying lithium storage mechanisms of negative electrode materials, which mainly exhibit relatively low potential and much higher capacity than commercial graphite and Li4Ti5O12, but the first loop coulomb efficiency of these materials is usually less than 80%, resulting in a low coulomb efficiency mechanism. The causes of initial negative ALL can usually be divided into the formation of SEI, the loss of active material and the appearance of dead lithium.Effect of negative active lithium lossIn practical applications of LIBs, some of the recyclable Li+ is consumed to form SEI on the negative surface, resulting in a lower first turn of CE, which in turn leads to a rapid capacity decay of the battery. As shown in Figure 2, the reversible capacity of the electrode is not reduced during this process, and when additional lithium sources are added to the system, the specific capacity of the battery will be restored to the ideal situation. The introduction of additional lithium sources will offset the specific energy gain brought by the pre-embedded lithium, and the effect of higher initial ALL on the specific capacity loss of the whole battery can be elaborated through theoretical calculation and analysis, and the specific energy based on the total mass of the negative electrode, the positive electrode and the lithium source can be obtainedFigure  shows the effect of different additional lithium sources on contrast energy. The specific capacity function of R with respect to the lithium source (cls) is shown for different negative lithium sources with initial CE of 50%, 70% and 90%, respectively. It can be seen that with the increase of cls, the R factor increases, while the decrease of CE will lead to a lower R factor. It can also be seen that when cls is greater than cc, it is necessary to use lithium sources to effectively improve the energy density. The analysis of these results can add more detailed parameters for different systems.A lithium source is added to the negative electrodeInitial ALL is caused by irreversible electrochemical processes on the negative electrode, so the most direct strategy for eliminating initial ALL is to prepare the pre-embedded lithium negative electrode by electrochemical and/or chemical strategies prior to pairing with the positive electrode. The positive electrode strategies can be divided into three categories: the half cell electrochemical method (HC-EM), the short circuit electrochemical method (SC-EM) and the chemical method (CM) as shown in the figure. After the negative electrode is pre-embedded with lithium, the initial ALL problems can be solved well, and the Coulomb efficiency of the entire battery first circle can be effectively improved.

Capacity attenuation mechanism of thick electrode of lithium ion battery
Capacity attenuation mechanism of thick electrode of lithium ion battery
At present, the need of high-endurance new energy vehicles forces the energy density of batteries to become higher and higher, and the use of thick electrodes with high load density active materials is one of the most practical strategies. However, their long cycle use process is accompanied by serious attenuation of electrochemical performance, power performance is not satisfied, and the capacity retention rate is getting worse and worse. So what exactly is causing the bottleneck of poor performance?Kyu-Young Park et al. explored the key processes that restrict battery decay by designing thick electrodes with different area degrees.1. Experimental designUsing NCM622: carbon black: PVDF 97:1.5:1.5 ratio and NMP mixed into pulp, after coating, drying and roller pressing, two kinds of electrodynamic half cells (2032) with different surface densities (20 and 28mg/cm-2) were prepared, and the pressure was between 2.8 and 2.9, in order to ensure better porosity. The charge and discharge cycle of the multi-channel device was carried out with the charge and discharge interval of 2.8-4.3V and the rate 1C was about 150mA/g. EIS, chemical composition and morphology were analyzed after every 20 cycles.2. Results and discussionThe following is the cross-section diagram of the electrodes of two thickths, respectively 70 and 100μm(standard electrode, thick electrode), the rest of the porosity, 1C current density and other design parameters are basically the same, and then the 1C cycle test is carried out. It is found in Figure c that although the capacity of the thick electrode of 100μm is only 40% higher than that of 70μm, but after 100 battery cycles, The thick electrode has a capacity retention rate of only 36%, while the standard electrode has a capacity retention rate of 76%. Even taking into account the volume specific capacity, the thick electrode after attenuation in Figure c is still much lower than the electrode. Interestingly, in Figure c, even in the initial cycle process, the circulation curves of the thick electrode and the standard electrode are close, and the attenuation degree is similar. Thick electrodes are getting worse.In illustrating the poor electrochemical performance observed, the authors note that thick electrodes may be subject to kinetic limitations caused by how fast or slow charge carriers migrate, which in electrochemical processes is either controlled by lithium-ion transport or by the transport of electrons that accumulate along the electrode. And, in each case, assuming that the main source of supply of electrons and lithium ions to the electrode is carried out from the electrode/collector interface and the electrode/electrolyte interface, in each case there will be a clear spatial distribution of both after the reaction.3. ConclusionBy using batteries designed with different electrode thickness, the authors verify that lithium ion diffusion is the limiting factor of charge transfer, but not electron transfer. This is also the reason why SOC at different locations is uneven, voltage drop IR increases, particle breakage and even battery diving under charge and discharge in batteries designed with thick electrodes. The electrode plate is designed according to the ion transport characteristics to avoid the phenomenon of excessive local current density, so as to improve the battery life

Relationship between lithium-ion battery capacity and internal resistance
Relationship between lithium-ion battery capacity and internal resistance
Relationship between reaction area and internal resistance of batteryWhen considering the resistance of a metal, the resistance formula R=ρ L/S holds, where ρ of the material itself represents the difficulty of transmitting electricity. If the index is certain, it is proportional to the length of the metal. Material, which is inversely proportional to the cross-sectional area.Taking this into account in the same way as the internal resistance of the battery, the internal resistance of the battery is equivalent to R, and the resistance value per unit area determined by the composition of the electrode mixture and the electrode structure is ρ, and the length in the direction of the electrode thickness is L. If the reaction area of the electrode is imagined as S, there is no problem.A similar formula R=ρL/S applies to the internal resistance R of the battery. In other words, the internal resistance of the battery is inversely proportional to the reaction area, and the larger the reaction area, the smaller the internal resistance.The relationship between reaction area and capacity of batteryAgain, let's look at the relationship between the reaction area and the capacity of the battery. Here is how to calculate the battery capacity from the reaction area (the area of the positive and negative coated parts relative to each other) and the coating mass (battery design table). The electrode structure is certain (ρ is a constant), the length of the electrode thickness direction (determined by the coating quality and porosity) is certain (L is a constant), and the capacity of the battery is proportional to the area S.We think it is easy to imagine that the larger the reaction area, the greater the capacity (that is, the reaction electricity). (If the reaction area is made using a laminated element that is also used in a laminated battery, etc., the reaction area will be proportional to the number of electrodes (the number of relative parts) and the number of components.)That is to say, for any battery, the larger the reaction area (the larger the size), the greater the capacity. In the formula, capacitance =KS (K is a constant), when the internal resistance R=ρL/S is connected through S, S= capacitance /K=ρL/R, then the capacitance =K'/R can be. It can be seen that when the parameters other than S are fixed, the capacitance is inversely proportional to the internal resistance.Using this concept, it is possible to predict the internal resistance and output of cells of different sizes (cells with different reaction regions) when using electrodes made of the same material and the same specifications (composition, porosity, etc.).

Who has mastered the solid-state battery technology, who has the new energy vehicle market!
The development of all-solid-state batteries began in the 1970s. Only later, with the technological innovation and large-scale commercial use of lithium-ion batteries in the early 2000s, the industry's attention to all-solid-state batteries has declined. Thirty years to the east, thirty years to the west, a new round of battery innovation cycle may be opened in 2030.Compared with liquid batteries, the core change of solid-state batteries is the introduction of solid electrolytes. According to the material type of solid electrolyte, the current solid state battery mainly includes oxides, sulfides, polymers and halides and other technical routes, and each route has its own advantages and disadvantages. For example, the oxide has high safety, but its easy brittleness leads to its complicated preparation process; Sulfide has high ionic conductivity, but the air stability is poor and H2S toxic gas is formed, and the cost is high. The polymer is relatively soft, the solid contact is the best, but the conductivity is low; However, halides are still mainly in the laboratory research stage.The whole industry placed the hope of the "next generation battery" on solid-state batteries, and even believed that this is the terminator of liquid lithium batteries, mainly due to the perfect properties of solid-state batteries.First, high security.Secondly, the energy density of all-solid-state batteries should also exceed that of liquid batteries, and the theoretical upper limit can reach 500 Wh/kg.Thirdly,Increased energy density means increased endurance.Lastly, the ion conduction mode of the liquid battery needs to go through solvation, desolvation and other processes, and the charging power is therefore limited.However, good all have a price, so far no manufacturer can produce solid-state batteries on a large scale, which actually reflects the difficulty of high.Since solid-state batteries still have so many challenges, why are so many companies insisting on developing solid-state batteries?1.the product characteristics of solid-state batteries can solve the safety and mileage anxiety of current new energy vehicle usersDue to the use of non-flammable, high and low temperature non-vaporization and non-solidification of solid electrolyte, solid-state batteries show strong high temperature safety, and maintain good low temperature characteristics to avoid low temperature battery life greatly reduced; In addition, solid-state batteries, due to their higher voltage window, can be further adapted to high-capacity positive and negative materials, such as lithium-rich manganese anode, silicon-based negative electrode and lithium metal negative electrode, so as to achieve higher energy density and increase the battery life under the same power.2.In the context of global competition for new energy vehicles, the competition for solid-state batteries is being staged around the worldIn the face of the industrial advantages formed by China in the development of global new energy vehicles, especially in the field of power batteries, which makes countries in Europe and the United States that need to transition to new energy urgently need to find new solutions, so the research and development of solid-state batteries has risen to become the national strategy of major countries in the world. For example, Japan is making national efforts to develop sulfide solid-state batteries, and strive to achieve 450Wh/L and 6C (@25 ° C) by 2027; The EU has also built a complete battery system from policy, innovation, and business, and plans to achieve polymer or composite solid-state batteries to break through 400-500Wh/kg and 800-1000+Wh/L during 2027-2030. The United States DOE plans to develop a solid-state battery in 2030 in 2021, with a production cost of less than $60 /kWh and an energy density of 500Wh/kg; Based on its K-Battery strategy, South Korea has also explicitly invested 40.6 trillion won to promote the commercial use of 400Wh/kg solid-state batteries in 2025-2028 and the loading of vehicles in 2030; China also set up the solid-state battery industry innovation consortium and the all-solid-state battery industry-university-research collaborative innovation platform in this half year to accelerate the breakthrough of (all) solid-state batteries and maintain the leading edge.

What is the Polymer Binder for Lithium-Ion Battery?
The Importance of the Polymer Binder for Lithium-Ion BatteryLithium-ion batteries have revolutionized the world of portable electronics and are increasingly being used in electric vehicles and renewable energy storage systems. One critical component of these batteries is the polymer binder, which plays a crucial role in their overall performance and durability. In this article, we will delve into the world of polymer binders for lithium-ion batteries and explore their importance and functions in detail.Understanding Polymer BindersPolymer binders are a vital component of the electrode materials in lithium-ion batteries. They are responsible for holding the active materials, such as lithium compounds, together in a stable structure. These binders are essentially polymers, which are large molecules consisting of repeating subunits. They are chosen for their ability to form a strong bond with the active materials and provide mechanical stability to the electrode.Enhancing Electrode AdhesionOne of the key functions of the polymer binder is to improve the adhesion between the active materials and the current collector. The active materials in a lithium-ion battery electrode are typically in the form of powders, which can easily detach and degrade during cycling. The polymer binder acts as a glue, binding the active materials to the current collector and preventing their detachment. This enhances the overall electrode stability and prolongs the battery's lifespan.Facilitating Ion TransportIn addition to improving electrode adhesion, the polymer binder also plays a crucial role in facilitating the transport of lithium ions within the battery. Lithium ions are the carriers of charge in lithium-ion batteries, and their efficient movement between the electrodes is essential for the battery's performance. The polymer binder helps create a network of interconnected pathways within the electrode, allowing for rapid and unhindered ion transport. This results in higher battery efficiency and faster charging/discharging rates.Ensuring Electrode FlexibilityFlexibility is another important characteristic of a polymer binder in lithium-ion batteries. As the battery undergoes repeated charge-discharge cycles, the electrode materials expand and contract. A rigid binder would restrict these movements, leading to mechanical stress and premature electrode degradation. Polymer binders with appropriate flexibility can accommodate the volume changes without compromising the structural integrity of the electrode, ensuring the long-term stability and performance of the battery.Preventing Electrode SwellingDuring battery operation, the active materials in the electrode can undergo a volume change, leading to electrode swelling. This swelling phenomenon can cause mechanical stress on the electrode and result in capacity loss or even battery failure. Polymer binders with good swelling resistance can effectively mitigate this issue by providing mechanical support and preventing excessive expansion of the electrode. This enhances the overall safety and reliability of lithium-ion batteries.Enhancing Thermal StabilityThermal stability is a critical aspect of lithium-ion batteries, especially in high-performance applications. Polymer binders with high thermal stability can withstand the elevated temperatures that can be generated during battery operation. They prevent the binder from decomposing or melting, which could lead to the loss of electrode integrity and reduced battery performance. Choosing a polymer binder with excellent thermal stability is therefore crucial to ensure the safe and reliable operation of lithium-ion batteries.Impact on Battery Energy DensityThe selection of the polymer binder can also significantly impact the energy density of a lithium-ion battery. Energy density refers to the amount of energy that can be stored within a given volume or weight of the battery. By choosing a polymer binder with low weight and high compatibility with the active materials, the overall weight of the battery can be reduced, resulting in higher energy density. This is particularly important for applications where lightweight and compact batteries are desired, such as electric vehicles.Considerations for Binder SelectionWhen selecting a polymer binder for lithium-ion batteries, several factors need to be considered. These include the binder's mechanical strength, adhesion properties, ionic conductivity, thermal stability, and compatibility with other battery components. Additionally, considerations such as cost, availability, and environmental impact should also be taken into account. A thorough understanding of these factors is crucial to choose the most suitable polymer binder for a specific battery application.Future Developments and InnovationsThe field of polymer binders for lithium-ion batteries is continuously evolving, with ongoing research and development aimed at improving battery performance and durability. Scientists and engineers are exploring new polymer materials and binder formulations to enhance adhesion, ionic conductivity, and thermal stability. Additionally, the use of advanced manufacturing techniques, such as 3D printing, is being investigated to create customized binder structures that optimize battery performance. These innovations are expected to drive the next generation of lithium-ion batteries with even higher energy density, longer lifespan, and improved safety.Quote Inquiry
