PURPOSE:To equalize the level of partial charge by continuously winding an anode plate containing a reduced active material, an anode plate containing an oxidized active material, a cathode plate and a separator. CONSTITUTION:Two anode plates are used which consists of a plate 3 completely charged and a plate 2 completely discharged by formation. The anode plates 2 and 3, a cathode plate 1 and a separator 4 are continuously wound to make an electrode group of the multipoint current collection type. As a result, the level of partial charge can be equalized. Furthermore, a stable product can be produced by reducing the variation in the capacity during high-rate discharge. |
