磷酸铁锂磁性杂质对电池自放电的影响
Effects of magnetic impurities in lithium iron phosphate on self-discharge of battery
摘要
Abstract
Magnetic impurities content in 3 kinds of commercialized lithium iron phosphate(LiFePO4) was investigated with magnetic measurements. The magnetic impurities such as ferrous phosphide(Fe2P),ferric oxide(Fe2O3) and metallic iron were existed in LiFePO4.The magnetic impurities would increase the self-discharge rate of finished battery.In experimental conditions, after stored under 328 K, the self-discharge rate of battery prepared with LiFePO4 of 1.63% (molar content) magnetic impurities was about 5.6 times than the one with 0.04% magnetic impurities.关键词
