PROBLEM TO BE SOLVED: To provide a battery, utilizing a gel electrolyte capable of improving lowering of mechanical strength of a gel electrolyte, lowering of thermal stability, and smallness of an electrolytic solution quantity capable of being held, and widening selection of a high polymer that is a raw material of the gel electrolyte. SOLUTION: In this battery separator, a mixture of a high polymer capable of holding an electrolytic solution and a resin such as polyolefin or the like. Thereby, since the high polymer is gelled by holding of an electrolytic solution, it functions as a solid electrolyte. Since a gel electrolyte is held by a resin membrane, mechanical strength is improved. In addition, a material of which forming of the self membrane has been impossible by a gel electrolyte solely can be used. |
