摘　　要：在1 mol/LLiPF6/EC+EMC(体积比1:1)电解液中,用恒流充放电池测试系统测试了2-甲氧基萘对磷酸铁锂电池电化学性能的影响,结果表明添加剂对电池容量特性基本没有影响.过充实验结果则表明添加5%的2-甲氧基萘表现出最优的磷酸铁锂电池的耐过充性能.2-Methoxynaphthalene was studied as an overcharge additive in 1 mol/L LiPF6/ethylene （EC） ＋methyl ethyl carbonate （EMC） （1：1 by volume） electrolyte for lithium ion batteries with LiFePO4 materials as cathode. The electrochemical performance of the batteries were studied by charge/discharge methode.The results indicated that 2-methoxynaphthalene does not have negative effect on the capacity of lithium-ion batteries, as welle as the most obvious for overcharge process of battery was observed when mass fraction of 2-methoxynaphthalene is 5 %.
