Abstract
[Object] It is an object to provide an injection method for injecting an electrolyte and an electrolyte injection apparatus which allow the electrolyte to be injected and filled into an electrode assembly within an outer can with favorable permeation, thereby easily manufacturing an electrolyte secondary battery having favorable cycle characteristics at good yield. [Solution] A solution injection nozzleis inserted into a solution injection holeof an outer canin which an electrode assemblyis stored, and the solution injection holeis hermetically sealed by a pressure reducing padprovided so as to surround a periphery of the solution injection nozzle. An inside of the outer canis made into a negative pressure through the pressure reducing pad, and an electrolyte L is supplied from the solution injection nozzleinto the outer can. The outer canis rotated with the solution injection nozzleas a rotation center.
