Patent number: 6676714Abstract: The invention provides for an apparatus and method for making a flexible battery that is electrolyte-tight by ensuring that electrolyte does not contact the unsealed portion of the battery enclosure when electrolyte is injected into the battery enclosure and before it is sealed. The apparatus for assembling a flexible battery comprises a support body adapted to support a battery enclosure having an electrode pouch and a fill opening located in an upper portion of the electrode pouch. The apparatus comprises a dispensing element having a discharge orifice that directs the flow of electrolyte inside the electrode pouch and away from the unsealed surfaces of the battery enclosure when the dispensing element is in the fill position. The method of assembling a pouch battery comprises arranging the battery enclosure so that the fill opening is located in an upper portion of the electrode pouch and dispensing the electrolyte into the electrode pouch.Type: GrantFiled: February 8, 2001Date of Patent: January 13, 2004Assignee: Eveready Battery Company, Inc.Inventor: Richard A.
