英文摘要：

Recent advance in the research of solid/solid interface between lithium electrode and polymer electrolytes （PE） in lithium polymer batteries is reviewed. Compared with Li/nonaqueous systems, the electrochemical reaction at the Li/PE interface and the influence of passivation layer on the electrochemical reaction are briefly introduced. The applications of different sophisticated electrochemical methods and spectroscopic methods, especially the in situ analysis techniques in Li/PE solid/solid system are discussed. In addition, different approaches for improving Li/PE interface include surface modifications of L-metal in the literature are also summarized.
