钴酸锂电池性能研究
Study on performance of LiCoO2 battery
摘要
Abstract
LiCoO2 battery has the character of high specific energy and long cycle life.So,LiCoO2battery is the first choice of power supply for many electric devices.In order to further understand the performance of lithium batteries,the basic performance of the 3.6 V/2.2 Ah LiCoO2 battery was studied.Firstly,the capacity experiment was carried out to study the discharge character at different discharge rates.Secondly,the charge and discharge electro motive force (EMF) of the battery was studied by the static method and the curve of EMF was analyzed.Finally,the chargedischarge ohm resistance,polarization resistance and total internal resistance of the battery under different SOC were analyzed.It is shown that when SOC＜0.1,the change of internal resistance is large.When the SOC is between 0.1 and 1.0,the change of resistance is small.关键词
