中文摘要：

为了降低Li／MnO2电池电解液的可燃性、提高电池的使用安全性，本文研究了以DMMP（Dimethyl methylphosphonate，甲基膦酸二甲酯）和TCEP（Tri（2-chloroethyl）phosphate，磷酸三（2-氯乙基）酯）作为阻燃添加剂，LiClO4为电解质盐的新型电解液，分别比较了添加DMMP和TCEP对电解液阻燃性、电池交流阻抗和放电性能的影响．

英文摘要：

Dimethyl methyl phosphonate （DMMP） and Tri （2-ch/oroethyl） phosphate （TCEP） were investigated as flame retardant additives in a 1. 0 mol/L LiClO4/PC ＋ DME ＋ DOL ＋ MA electrolyte systcrm. The flammability, AC Impedance and elcctrochemiscal perfarmance of electrolytes revealed that the addison of DMMP,to electrolytcs provided a more significant suppression in flamunability of electrolyre and caused less degradation on electrochemical performance than on TCEP. The discharge polarization curves for Li/MnO2 batteries using 1 mol/L LiClO4/PC ＋ DME ＋ DOL ＋ MA with DMMP at different temperatures were also studied. DMMP was found to be a better flame, retardant additive in improving the safty of Li/MnO2 batteries.
