摘　　要：通过原子吸收光谱、热失重实验,分析了Li/(MnO2+CFx)电池在贮存中产生气体的种类、产气机理、产气的关键因素。发现电池产生气体的成分主要是H2和CO2,产气最主要的原因是水分存在,其次是原材料本身的特性,通过原材料的处理无法解决电池贮存过程中的产气问题,而通过电池预放电可以解决。According to atomic absorptior spectroscopy and thermo-gravimetric analysis, gas species and mechanism and key factor of Li/（MnO2 ＋CFx） batteries＇ producing gas in storage were studied. It is found that main components of the producing gas were H2 and CO2, the major reason was water＇s existence, the second reason was materials＂ speciality. Dealing with materials, the problem of batteries＂ producing gas couldn＂t be solved, but pre-discharge can solve it.
