摘要:
There is provided a method for producing a hybrid negative plate for a lead-acid storage battery which is improved in the production working efficiency and the productivity and enhances the quick charge and discharge characteristics and the discharge characteristics at a low temperature under PSOC of a lead-acid storage battery. A carbon mixture sheet produced by such a way that a carbon mixture prepared by mixing two types of carbon materials consisting of a first carbon material having electroconductivity and a second carbon material having capacitor capacitance and/or pseudocapacitor capacitance, and at least a binder, is adhered by pressure to the surface of a negative plate in a wet state, so that a hybrid negative plate is produced. The lead-acid storage battery provided with the hybrid negative plate is improved in the discharge characteristics.
