Poly (methyl methacrylate) (PMMA)/poly (vinylidene fluoride) (PVDF) gel polymer membranes with different mor-phology were formed by controlling the membrane formation processes. The nonporous blending membrane was obtained by blen-ding and coating, the less-porous cross-linking membrane was obtained by cross-linking after coating, the porous cross-linking mem-brane was obtained by cross-linking before coating. The order of their ionic conductivity was the porous cross-linking membrane> the nonporous cross-linking membrane > the less-porous cross-linking membrane. The capacity retention rate of the principle cell using the porous cress-linking membrane at the 50th cycle was higher than 92% when charge-discharged at 0.2 C in 3.0～4.3 V.
