Abstract

The present invention provides a porous polymer membrane obtained through the use of a polyurethane-treated polyvinylacetal polymer, and a preparation method for said porous polymer membrane. Through-pores are evenly distributed across the porous membrane, giving said membrane excellent electrolytic liquid adsorption capabilities and allowing for a liquid adsorption rate of 300% or higher. Electrolytic liquid adsorption and swelling results in system gelation, and the porous membrane and gel system can thereby remain stable for a long period of time. The near-liquid electrolyte in the present invention has an average electro-conductivity value of 1.0 x 10-3S/cm, an electrochemical stability window of 2.0V-5.0V, markedly improved mechanical properties and electrocompatibility, and can act as a gel polymer electrolyte, thereby enhancing battery safety. The invention also renders unnecessary the use of a liquid electrolyte system or other battery system diaphragm as a support.
