LEAD-ACID BATTERY AND METHOD FOR MANUFACTURING A COMPOSITE NEGATIVE CAPACITOR PLATE FOR USE IN A LEAD-ACID BATTERY

摘要

The present invention provides a method of manufacturing a composite capacitor negative electrode plate for a lead-acid battery, which improves the manufacturing work efficiency and productivity and improves the rapid charge-discharge characteristic and the low-temperature discharge characteristic in the PSOC of the lead-acid battery. A carbon composite material produced by forming a carbon mixed material in which a first carbon material having electrical conductivity and a second carbon material composed of a second carbon material having a capacitor capacity and / or a pseudo capacitor capacity and at least a binder are mixed, The sheet is produced by compression-coating the surface of the wet-state negative active material filling plate. The lead-acid battery having the composite capacitor negative electrode plate improves the discharge characteristic.
