摘　　要：为探究恒流预放电模式与电性能之间的关系,使用多种恒流预放电模式对制备的锂锰电池进行处理,并对高温存储前后的电池进行电性能测试。利用相关与回归分析的方法,研究锂锰电池预放电时间、电流和预放电容量与电性能的关系。与小电流(30 mA)相比,使用大电流(80 mA)恒流预放电,可降低电池的内阻。高温存储后,经大电流预放电后的电池内阻仅上升18.72%,容量仍有存储前的97.27%。In order to explore the relation between galvanostatic pre-discharge modes and electric performance,several galvanostatic pre-discharge modes were used to treat prepared Li-MnO_(2) batteries,the electrical performance of batteries before and after stored at high temperature was tested.The relation between the pre-discharge time,current,pre-discharge capacity and electric performance of Li-MnO_(2) battery was investigated by using the correlation and regression analysis method.The high current(80 mA)galvanostatic pre-discharge could reduce the internal resistance of the battery compared with low current(30 mA).After high-temperature storage,the internal resistance of the battery with high current pre-discharge increased only 18.72%,the capacity remained 97.27%of the one before storage.
