摘要
动力型锂离子电池安全性与其热特性具有十分密切的关系。对38120型高功率圆柱电池的引流结构进行了优化,优化后的电池结构大大改善了电池的大电流放电能力。而后以加速量热仪测定了电池在不同放电倍率下的温升、热功率、比热容等参数,对电池的放热特性进行了研究。
The safety of high power lithium ion battery was highly related to its thermal property. In this work, the current-collecting structure of 38120-type cell was optimized, which enhanced the rate property of the cells. Cells with optimized structure were then discharged at different rate in accelerating rate calorimeter （ARC）, and thermal parameters were measured.
