锂锰动力电池滥用条件下安全性能研究

Study on safety performance of Li-MnO_2 power batteries under deviant use

采用电解MnO2和锂作为正负极材料制作成65 Ah电池及并联成325 Ah锂锰动力电池,测试其短路、加热、过充电、过放电、海水浸泡、针刺、挤压、火焰及跌落的安全性能。研究发现,通过适当的结构和工艺设计及必要保护后,大容量锂锰动力电池可以满足苛刻滥用条件下的安全性能。

The power batteries （65 Ah and 325 Ah connected in parallel） were manufactured with the electrolytic MnO2 as cathode and Li as anode. Short circuit, heat, overcharge, over-discharge, sea-water, puncture, extrusion, flame and fall performance of batteries were tested. The research shows that the safety performance of Li-MnO2 power batteries under rigorous deviant use can be satisfied through necessary safeguard of appropriate design of structure and techniques.
