ELECTROLYTIC FILLING DEVICE FOR SEALED TYPE BATTERY

摘要

PURPOSE:To uniformly fill each cell with an electrolyte by cutting each one end of a number of mutually connected independent packages in which almost the same amount of the electrolyte is sealed and inserting each one end in a number of injection ports formed every cells. CONSTITUTION:For example, a sealed type battery 15 consists of three cells and injection ports 16 to 18 that inject an electrolyte are formed on the top every cells. Three independent packages 19 to 21 are connected mutually and provided corresponding to each cell of the battery 15 so as to inject the electrolyte. Almost the same amount of the electrolyte is sealed in the packages 19 to 21. When the battery is coated with the electrolyte, the respective lower ends of the packages 19 to 21 are cut and inserted in the injection ports 16 to 18 and then each cell of the battery 15 can uniformly be filled with the electrolyte by cutting the respective upper ends of the packages 19 to 21. After the filling of the electrolyte is completed, mutually connected caps 22 to 24 are fit to the injection ports 16 to 18 and a sealed structure is made possible.
