| 发明名称 | Battery and method for producing the same | ||
| 摘要 | A method for producing a battery includes forming a space by expanding a liquid housing portion, the liquid housing portion being present at one end of an outer package that houses a battery element, through supply of gas from an opening portion formed at the other end of the outer package; injecting an electrolytic solution from the opening portion to store the electrolytic solution in the space of the liquid housing portion; degassing the outer package through the opening portion in a vacuum state; sealing the opening portion; and impregnating the electrolytic solution into the battery element. | ||

| 主权项 | 1. A method for producing a battery comprising: forming a space by expanding a liquid housing portion, the liquid housing portion being present at one end of an outer package that houses a battery element, through supply of gas from an opening portion formed at the other end of the outer package, wherein the opening portion, the battery element, and the liquid housing portion collectively define a longitudinal axis; folding the outer package along a folding portion extending substantially parallel to the longitudinal axis and spaced away from positive and negative electrode leads, thereby sandwiching the positive and negative electrode leads; injecting an electrolytic solution from the opening portion to store the electrolytic solution in the space of the liquid housing portion; degassing the outer package through the opening portion in a vacuum state; sealing the opening portion; and impregnating the electrolytic solution into the battery element. | ||
