Abstract: Excellent properties of lithium battery with polymer electrolyte are reviewed. From the analysis of polymer matrix and electrolyte，the development of gel polymer electrolyte，micro–porous polymer electrolyte and composite polymer electrolyte in recent years is introduced. Their preparation method，properties and features are compared. The effects of Li–salts, plasticizers，ionic liquids and single–ion conductors on polymer electrolyte properties are summarized. In addition，the developing trends of polymer electrolyte and polymer lithium battery are presented.
