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.

摘要： Disclosed are an all-solid-state battery having high energy density and a method for manufacturing the same. One battery structure is pressed instead of pressing each cell unit, an amount of first or second electrode current collectors consumed is reduced, and insulating members are used, thereby simplifying a manufacturing process of the all-solid-state battery and allowing the all-solid-state battery to have high energy density and a stable structure.
