Electrical battery assembly and method of manufacture |
摘要 |
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.
