Study on the gas generation in Polymer Lithium-ion Battery [PDF]
, 2004 锂离子电池在首次充电的过程中，随着SEI层的形成，电解液溶剂会发生还原分解，从而产生气体。此外，由于电池外包装材料的密封性不好，或电池在生产过程中引入一些杂质，也会造成电池在储存阶段发生气胀。这些问题，长期以来一直是锂离子电池产业化进程的困扰因素之一。目前，人们对SEI层的机理研究相对较多，而影响SEI层性质的各种因素研究较少，尤其是对锂离子电池产气机理的研究更少。 通常人们主要是从溶剂的粘度、介电常数、凝固点以及沸点等方面出发，来考察组成的电解液溶剂体系的电导率以及对电池温度性能的影响。但在实际工作中，

Gaoya dianqi, 1983 对于高压开关导电回路回路电阻的测量,一直采用着蓄电池压降法。这种方法的缺点是:价格昂贵,寿命不长,且需要不断充电,给运行人员造成很大麻烦。后来,人们改用双臂电桥。此种方法的优点是携带方便、操作简单;缺点是通过电流较小,使用受到局限。

Guangtongxin yanjiu, 1977 <正> 前言随着通信事业的发展,通信设备容量增大,方式增多,各种通信设备要求供给的电源电压种类不一,如果使用蓄电池以保证对通信设备的不间断供电,势必使电池组的种类繁杂,投资增多,维护麻烦。因此,现在多使用逆变器,用某一电压的蓄电池组,将直流电源转变为与市电同电压同频率的正弦交流电源,送至各种通信设备,以代替市电。这样,电池组种类单一,投资少,维护方便。
