BATTERY AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To improve the reliability of a seal part of a seal bag while preventing the adhesion of the electrolyte the seal part by forming a first seal bag for sealing a battery element and the electrolyte and a second seal bag for sealing the first seal bag for sealing the battery element and the electrolyte while extending collector tabs outside thereof. SOLUTION: A battery element 1 has the layered structure formed of a positive electrode 2, a negative electrode 3, a separator 4 and an electrolyte layer 5. The separator 4 and the electrolyte layer 5 function as an ion conductive layer. The battery element 1 is sealed in a first seal bag 21 made of the insulating polymer material, and a first bag seal part 22 in the periphery of the first seal bag 1 is adhered for sealing. The battery element 1 sealed in the first seal bag 2 is housed in a second seal bag 23 made of the insulating polymer material. A positive electrode collector tab 8 and a negative electrode collector tab 9 formed of a collector for electrically connecting the battery element 1 to an external circuit of various electronic equipment are connected to the positive electrode 2 and the negative electrode 3 inside of the first seal bag 21, and adhered to the first seal bag 21 and the second seal bag 23 through a metal adhering material 10.
