Title:
A manufacturing method of a nonaqueous electrolyte rechargeable battery
Document Type and Number:
Japanese Patent JP6024990
Kind Code:
B2
Abstract:
This invention provides a method of manufacturing a nonaqueous electrolyte secondary batteries which includes placing an electrode assembly in a hermetically sealable battery case, injecting a nonaqueous electrolyte into the battery case after the battery case has been set in a pressure-reduced state, and sealing the battery case under atmospheric pressure conditions. Sealing of the battery case is carried out before a given amount of the injected electrolyte completely impregnates the interior of the electrode assembly. As a result, the remaining nonaqueous electrolyte impregnates the interior of the electrode assembly after sealing, thereby making the pressure of voids within the battery case lower than atmospheric pressure.
