Abstract:
    The present invention relates to a kind of composite type full-solid polymer electrolyte for secondary lithium cell and its preparation method. It includes polyoxyethylene, metal lithium salt and modification metapore molecular sieve, in which the mixing ratio of polyoxyethylene and metal lithium salt O/Li is 8-20, the modification meapore molecular sieve content is 5%-25% of polyoxyethylene content. Its preparation method includes the following steps: mixing metal lithium salt and modification metapore molecular sieve, adding acetonitrile solvent to obtain slurry, adding polyoxyethylene powder into said slurry to obtain suspension, pouring said suspension into polytetrafluoroethylene mould, evaporating solvent, drying, removing residual solvent so as to obtain the invented product.
