摘要:
[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.
摘要:
The present invention generally relates to electrodes for use in lead-acid battery systems, batteries and electrical storage devices thereof, and methods for producing the electrodes, batteries and electrical storage devices. In particular, the electrodes comprise active battery material for a lead-acid storage battery, wherein the surface of the electrode is provided with a coating layer comprising a carbon mixture containing composite carbon particles, wherein each of the composite carbon particles comprises a particle of a first capacitor carbon material combined with particles of a second electrically conductive carbon material. The electrical storage devices and batteries comprising the electrodes are, for example, particularly suitable for use in hybrid electric vehicles requiring a repeated rapid charge/discharge operation in the PSOC, idling-stop system vehicles, and in industrial applications such as wind power generation, and photovoltaic power generation.
