[Problem] To provide a hybrid negative plate for a lead-acid storage battery, that inhibits decrease in hydrogen gas evolution potential and improves rapid discharge cycle characteristics in PSOC.
[Means for Resolution] In a hybrid negative plate for a lead-acid storage battery, comprising a negative electrode active material-filled plate having formed on the surface thereof a coating layer of a carbon mixture comprising a carbon material for ensuring conductivity, activated carbon for ensuring capacitor capacity and/or pseudocapacitor capacity, and at least a binder, activated carbon modified with a functional group is used as the activated carbon. Preferably, activated carbon modified with an acidic surface functional group is used.
