4 ways to improve low temperature performance of lifpo4 battery

4 ways to improve low temperature performance of lifpo4 battery

The cathode material is a key part of lithium-ion batteries and must meet the requirements of high capacity, strong stability and low toxicity. Compared with other cathode materials, LiFePO4 electrode materials have many advantages, such as higher theoretical specific capacity, stable working voltage, stable structure, good cyclability, low cost of raw materials and environmental friendliness. […]

Several methods of polymer lithium battery replenishment

During the first charging process of the polymer lithium battery, the organic electrolyte will be reduced and decomposed on the surface of the negative electrode such as graphite to form a solid electrolyte phase interface (SEI) film, which permanently consumes a large amount of lithium from the positive electrode, resulting in the Coulombic efficiency (ICE)

Performance analysis of lithium-ion power battery in low temperature environment

Performance analysis of lithium ion power battery in low temperature environment

The characteristics of lithium-ion power batteries are significantly affected by ambient temperature, especially in low-temperature environments, where the available energy and power attenuate seriously, and long-term use in low-temperature environments will accelerate the aging of lithium-ion power batteries and shorten their service life. With the rapid development of the new energy vehicle industry, some of
