How to improve the safety and service life of lithium-ion battery lithium battery? During the use of lithium-ion batteries, there is a problem that is often plagued our consumers. It is the safety of lithium-ion batteries. If our lithium-ion battery is unreliable, we cannot use it with confidence.
According to the use environment, the use of strategies for lithium-ion batteries in time, on the one hand, the safety of the lithium-ion battery can also ensure the performance of lithium ion battery and life. How to improve the safety of lithium-ion battery lithium battery? 1. The solution of the negative electrode material will completely separate the large particle size and ultrafine powder to the required particle size, preventing the local electrochemical reaction from being too violent and negative and negative, and improves the safety of the lithium battery.
Improve the surface porosity of the material, this can increase the capacity of 10%, while the C / A is constant, the security is greatly improved. The result of the solution has better compatibility with the surface of the negative electrode material to the electrolyte, which has prompted the formation and stability of the SEI film. 2.
Controlling the pulping process of pulping processes using advanced process methods and special chemical reagents, so that the surface tension between the groups of the positive and negative slurry is minimized. Improve compatibility between groups, preventing the material in the agitation process "reunion". The gap of the coating time-based material and the nozzle should be controlled below 0.
2 mm, which is smoothly free of particles, depressions, scratches such as the surface of the plate. The slurry should be stored for more than 6 hours, the slurry viscosity is stable, and the inside of the slurry has no self-phenomenon. The average slurry guarantees the average of the positive and negative electrode distribution, thereby improving the consistency, safety of the lithium battery.
3. Advanced pole manufacturing equipment can ensure the stability and consistency of the quality of the pieces, greatly improve the unsales of the battery, and reduce the emergence of unsafe lithium battery. The upper density error value of the coating machine single-chip plate should be less than ± 2%, the length of the plate length and the gap size error should be less than 2 mm.
The roller shaft taper and radial beat should be not more than 4 μm, so that the consistency of the thickness of the plate can be guaranteed. The equipment should be equipped with a sound vacuum system to prevent micro-teleconcopying of the cells caused by floating particles, thereby ensuring the self-discharge performance of the lithium battery. How to improve the life of lithium-ion battery lithium battery? ● The short circuit is short-circuited in the anti-blocking, which is a serious problem that affects the safety of lithium ion battery.
Due to the short circuit in the lithium-ion battery caused by lithium delegated crystals, excess objects, it is often caused serious safety problems. In order to solve the internal short circuit incident caused by lithium branch growth, people have designed a variety of ways to monitor the growth of lithium-ion batteries. ● Intelligent self-repair With the popularity of lithium-ion batteries, the opportunity of various damage to the lithium-ion battery is also new, if the lithium-ion battery can realize self-repair function like organisms, this about extending lithium ion batteries The service life, reducing the safety risks of lithium-ion batteries have a very important meaning.
● The function of the lithium-ion battery protective plate lithium-ion battery protective plate is important to protect the battery cells of the charging battery, maintaining the safety and stability in the battery charge and discharge process, and plays a need for a critical purpose for the performance of the entire battery circuit system. Lithium-ion battery manufacturers should improve the safety of lithium-ion batteries, BMS system manufacturers, to understand the performance of the battery, based on the safety design principle of the power lithium battery, and correctly Use is the final barrier to ensure battery safety. .
