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.

Method for producing hybrid negative plate for lead-acid storage battery and lead-acid storage battery

To provide a method for producing a lead-acid battery negative plate for use in a storage battery which provides improved deteriorated rapid discharge characteristics by preventing an interfacial separation between a negative active material-filled plate and a carbon mixture-coated layer, which is a problem in a negative plate having such a configuration that the carbon mixture coated layer is formed on the surface of the negative active material-filled plate. A coating layer of a carbon mixture is formed at least in a part of a surface of a negative active material-filled plate. The carbon mixture is prepared by mixing two kinds of carbon materials consisting of a first carbon material having conductive properties and a second carbon material having capacitive capacitance and/or pseudo capacitive capacitance and a binding agent. Subsequently, a sufficient amount of lead ions are generated enough to be moved from the negative active material-filled plate into the carbon mixture-coated layer. Thereafter, a formation treatment or an initial charge treatment is performed to precipitate lead so that the carbon mixture-coated layer and the negative plate are connected and integrated, at least in a part of a respective interfacial surface thereof, by the precipitated lead.
