摘要
通过预放电的形式掺杂锂离子,有助于降低锂氟化碳二氧化锰复合电池的内阻,减缓电池放电初期电压滞后现象,同时考察了经过高温储存后,电池放电的压降情况及放电性能,实验结果显示,10%锂离子掺杂电池在1C倍率下放电,低波电压较未掺杂电池提高了0.4V,0.5C倍率下放电平台电压增加0.15V,0.1C倍率下放电经高温71℃储存21天未出现明显电压滞后。
Doping lithium ions in the form of pre-discharge helps to reduce the internal resistance of Li/(CFx+MnO2)composite battery,slow down the voltage hysteresis at the initial stage of battery discharge,and investigate the voltage drop of battery discharge after high temperature storage.The experimental results show that the 10%lithium ion doped battery discharges at 1 C rate,the low wave voltage is increased by 0.4 Vcompared with the undoped battery,and the discharge platform voltage is increased by 0.15 Vat 0.5 Crate.The discharge curve at 0.1 Crate was not significant voltage hysteresis after a high temperature of 71℃for 21 days storage.
