圆柱LiFePO4电池低温性能的研究
Study on low temperature performance of cylinder LiFePO4 battery
摘要
Abstract
The cylinder LiFePO4 batteries have excellent cycle and rate performance, but the discharge capacity at-40℃is less than 40%of the capacity at 25 ℃. The low temperature performance of cylinder lithium ion battery prepared through smal particle LiFePO4, composite graphite anode and special low temperature electrolyte was improved greatly. The 0.5 discharge capacity of the batteries at-40℃can reach above 75%of the capacity at room temperature. But the cycle performance decreases, as the capacity retention is about 80%after 1 000 cycles at room temperature and 1 .关键词
