Abstract：
 In the in-situ compounding process of preparing microporous polymer electrolyte, compounded microporous film is prepared through combined phase transferring process and gel-sol process with the copolymer of vinylidene fluoride or hexafluoro propylene as substrate and silicate as the precursor of silica; and the compounded microporous film is then soaked with non-aqueous electrolyte solution to obtain the in-situ compounded polymer electrolyte. During the filming process, steam penetration is utilized for the phase separation of substrate polymer and silica is prepared via the hydrolysis and condensation of silicate in solution. The present invention avoids the aggregation of silica and makes silica combined tightly with the polymer substrate, so that the prepared microporous polymer electrolyte has high conductivity and high electrochemical stability.
