ALKALINE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an alkali battery of high capacity, excellent impact resistance and excellent high efficiency discharging by fixing the outermost circumference of the electrode group with a conductive tape. SOLUTION: In this alkali battery, a separator is laid between a belt shaped positive electrode and a belt shaped negative electrode and the electrode group is rolled in spiral shape and is housed in a cell case and the top of the cell case is sealed with a seal plate. The electrode group is fixed with a conductive tape at the outer circumference.
