PURPOSE:To effectively utilize the space inside a battery and to make high rate discharge possible by separately manufacture an electrolyte container, combining with an electrode group container, sliding, then bursting a thin aluminium film in the electrolyte container to pour an electrolyte. CONSTITUTION:A container 1a for an electrode group 5 and a container 1b for an electrolyte are separately manufactured. Two containers 1a, 1b are combined and slided and pushed until the second stopper 2 reaches a groove installed in the container 1b. A battery is usually stored in this state. When the battery is used, the container 1a is deeply pushed into the container 1b to burst a thin aluminium film 6 and to supply an electrolyte 7. Thereby, voltage delay is prevented and high rate discharge is made possible. Since the space inside the battery is effectively utilized, the battery is made compact even if the output density is the same. |
