| Abstract: | The influences 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 ethanolamine did not affect the compatibility of electrolyte and anode or cathode,could restrain the LiPF_6 from hydrolysis and pyrogenic decomposition,reduced the capacity loss of battery by 50%,resulting in the improvement of the stability of electrolyte and cycle life of batteries. |
