摘要： Disclosed are a hybrid solid electrolyte sheet and a method of manufacturing the same. The hybrid solid electrolyte sheet includes a hybrid solid electrolyte layer including a gel polymer electrolyte, thereby securing flexibility and alleviating brittleness. In addition, the hybrid solid electrolyte sheet includes a porous polymer film having a plurality of pores, thus minimizing the content of the acrylate monomer in the pores thereof and providing advantages of maintaining the continuity of the solid electrolyte while minimizing a decrease in ionic conductivity.
