通过电性能测试与扫描电子显微镜(SEM)、电感耦合等离子光谱(ICP)、X射线衍射(XRD)，能谱定量分析(EDS)等方法对外壳发生腐蚀的铝壳锂离子动力电池和正常电池进行了研究，并分析了腐蚀发生的条件。研究发现,腐蚀电池在循环、存储以及放电倍率等性能上有明显下降，分析表明当电池内部负极耳与铝壳内壁接触并经过半年以上的放置或者使用时，有可能会发生腐蚀反应，腐蚀首先发生在铝壳内壁，然后逐步发展到铝壳外侧，腐蚀产物主要是Li2CO3和铝盐。

Electrical property test, the SEM, ICP, XRD and EDS were used to study the lithium-ion power batteries; including decomposed and normal batteries with corroded aluminum casing, and the corrosion conditions were discussed. It was found that the cycle life, storage and discharge rate of corrosion batteries had a rapid declining. When the anode tab was contacted with the aluminum inner wall of aluminum lithium-ion battery, corrosion reaction might occur after more than six months of placement or using, the corrosion reaction occurd in the aluminum inner wall first, and then gradually developed into the outer aluminum. The main corrosion products were Li2CO3 and aluminum salts.
