COMPOSITION FOR GEL POLYMER ELECTROLYTE AND LITHIUM SECONDARY BATTERY COMPRISING SAME |
摘要 |
Provided are a composition for a gel polymer electrolyte including i) an electrolyte solution solvent, ii) an ionizable lithium salt, iii) a polymerization initiator, and iv) a monomer having a functional group bondable to metal ions, and a lithium secondary battery including the composition for a gel polymer electrolyte. In a case where the composition for a gel polymer electrolyte of the present invention is used in a lithium secondary battery, since the movement of metal ions dissolved from a cathode to an anode may be prevented or the precipitation of metal on the anode may be reduced, the lifetime of the battery may not only be improved but capacity characteristics of the battery may also be excellent even in the case in which the battery is charged at a high voltage as well as normal voltage |
