摘　　要： 用循环伏安、电池充放电和化学分析等方法,研究了乙醇胺对电解液稳定性和锂离子电池循环寿命的影响。乙醇胺的加入,不影响电解液与正、负极的相容性,能抑制电解液中LiPF6的水解和热解反应,使电池的容量衰减率降低50%,提高了电解液的稳定性和电池的循环寿命。 The influenees of ethanolamine on the stability of electrolyte and cycle life of Li-ion batteries were studied by cycling voltammetry, charge-discharge of battery and chemical analysis. The addition of ethanolamlne did not affect the compatibility of electrolyte and anode or cathode, could restrain the LiPF6 from hydrolysis and pyrogenie decomposition, reduced the eapacity loss of hattery by 50%, resulting in the improvement of the stability of electrolyte and cycle life of batteries.
