Solid polymer electrolytes still face many problems for the development of energy devices. A new hybrid compound (POSS) grafted with a low molecular weight PEO segment was introduced to inhibit polymer crystallization and improve the ion conductivity. The microscopic interaction sites between Li+ and other atoms were studied in the grafted systems. The glass transition temperature shows that the grafting of POSS can effectively inhibit the crystallization of the polymer and form more microscopic amorphous regions. Comparing with a blank system and blending system, the improved electrical conductivity of Li ions was obtained.
