摘要: An overview of our research is presented on developing composite polymer electrolytes (CPEs) based low-molecular weight polyethylene oxide (PEO) (namely, poly(ethylene glycol) dimethyl ether), lithium salts (e.g. triflate, imide, etc.), and fumed silica. These CPEs demonstrate high room-temperature conductivites (>10−3 S/cm), mechanical strength, form stable interfaces with metal as a result the The surface groups silica determine properties CPE while PEO salt ionic transport properties. show promise for next generation rechargeable batteries.
