Abstract
Disclosed is an electrode for a lead storage battery that has good initial output characteristics and causes little or no reduction in output characteristics after charge-discharge cycle. The electrode comprises an electrode active material layer and a current collector. The electrode active material layer comprises a layer containing a lead-containing material as an electrode active material and a layer containing a porous carbonaceous material as an electrode active material. The electrode satisfies a requirement represented by the following equation: B/(A+B)×100=1.0 to 90.0% wherein A represents the weight of lead atoms contained in the electrode active material layer; and B represents the weight of the porous carbonaceous material contained in the electrode active material layer. The density of the layer containing the porous carbonaceous material is 0.40 to 0.80 g/cm. Also disclosed is a lead storage battery using the electrode in at least one of a positive electrode and a negative electrode.
