What factors will affect the low temperature performance of lithium iron phosphate batteries?

What are the factors that affect the low-temperature performance of lithium iron phosphate batteries? 1. Processing environment Lithium iron phosphate battery is a high-tech product with many chemical raw materials and complicated processes. Its processing environment has high requirements on temperature, humidity, dust, etc. If it is not controlled in place, battery quality will fluctuate. 2. Poor conductivity and slow diffusion of lithium ions. When charging and discharging at a high rate, the actual specific capacity is low. This problem is a difficulty that restricts the development of the lithium iron phosphate battery industry. The reason why lithium iron phosphate has not been widely used so late is an important issue. 3. The influence of materials The lithium iron phosphate positive electrode itself has relatively poor electronic conductivity, and it is more prone to polarization, which reduces the performance of the capacity; the negative electrode is important for low-temperature charging, because it will affect safety issues; the electrolyte is , Maybe the viscosity will increase at low temperature, and the lithium ion migration resistance will increase; the fourth is the binder, which now has a relatively large impact on the low temperature performance of the battery. What are the factors that affect the consistency of lithium iron phosphate batteries? After the lithium batteries are grouped, it is difficult to maintain the battery consistency in the lithium battery pack, and the service life will be greatly shortened. Therefore, the control of the battery consistency in the lithium iron phosphate battery pack becomes extremely important. The quality of raw materials: In particular, lithium iron phosphate materials are new things, and their manufacturing equipment and synthesis process are not safe and mature, and the quality is prone to fluctuations, which affects the consistency of battery products.
