Publication number: 20150047181Abstract: An electric storage battery and method of manufacture thereof characterized by a feedthrough pin which is internally directly physically and electrically connected to an inner end of a positive electrode substrate. A C-shaped mandrel extends around the pin and substrate end enabling the pin/mandrel to be used during the manufacturing process as an arbor to facilitate winding layers of a spiral jellyroll electrode assembly. The pin additionally extends from the battery case and in the final product constitutes one of the battery terminals with the battery case comprising the other terminal. Active material is removed from both sides of the outer end of the negative electrode in the jellyroll to allow room for adhesive tape to secure the jellyroll. The electrolyte is injected through the open end of the case after the endcap is welded to the negative electrode but before sealing the endcap to the case. The electrolyte is preferably injected through the C-shaped mandrel to facilitate and speed filling.Type: ApplicationFiled: August 7, 2014Publication date: February 19, 2015Inventors: David M.

Patent number: 7070881Abstract: The invention provides electrical storage battery assemblies and related methods for assembling such batteries. A battery assembly includes positive and negative electrode sheets and separator sheets sandwiched together and wrapped around a central mandrel to provide a spiral sandwich electrode assembly. The electrode assembly is housed inside a case that includes a case housing open at two ends and covers closing the two openings. The central mandrel of the electrode assembly is in electrical contact with one of the electrode sheets and a first battery terminal that passes through the case. A projecting member on the central mandrel provides the electrical connection between the electrode and the first battery terminal. The other electrode is in electrical contact with the case. A first insulator lies between the electrode assembly and the projecting member. A second insulator is positioned between the projecting member and the case.Type: GrantFiled: August 15, 2002Date of Patent: July 4, 2006Assignee: Quallion LLCInventors: Clay Kishiyama, Andrew Szyszkowski, Hisashi Tsukamoto
