Lead-coated carbon composite material and application thereof

The invention relates to a lead-coated carbon composite material and an application thereof. The lead-coated carbon composite material is characterized in that lead (2) is used for coating the surrounding of a powder-form or rod-form carbon-based material (1) for extrusion moulding, or the powder-form carbon-based material (1) is compressed to a carbon-based grid or is wound to obtain the carbon-based grid after being made to a filament state, and then a lead sheath is used for coating on an outer layer of the carbon-based grid. The lead-coated carbon composite material can be used for making the grid for a storage battery electrode plate, volume ratio energy and discharge capacity of a storage battery can be effectively increased; the carbon-based material with light weight and strong conductivity can be taken as a conductive inner core, a lead layer with strong corrosion resistance and electrochemistry performance is used for coating outer part, so that lead amount is reduced, grid weight is greatly reduced, cell weight is greatly reduced, and environmental pollution can be mitigated.
