Problems solved by technology

[0002] The existing lead-acid battery plate grid is basically based on an alloy with a high lead content, which is not only heavy in weight, but also high in cost
In practical applications, the general direction of research and development is to try to improve the mechanical strength, electrical conductivity and corrosion resistance of the electrode by changing the composition of the lead alloy, but so far, the technology is not yet mature.

Embodiment 1

[0016] One embodiment of the present invention can be made of lead 2 wrapped around the carbon-based material 1 and then extruded, such as figure 1 The lead-coated carbon composite shown in 3.

[0017] Among them, the carbon-based material 1 can be powdered or rod-shaped as the matrix, and its main component can be activated carbon or carbon alloy material, and can also add conductive agent and binder, for example, can add copper powder, silver powder, aluminum powder, Graphite, superconducting carbon, graphite milk or conductive carbon black can be used as a conductive agent, and clay or resin can be added as a binder; lead 2 can be pure lead or alloy lead, and alloy lead can be lead-antimony alloy, lead-calcium alloy, lead-antimony alloy Arsenic tin alloy or lead calcium tin aluminum alloy.

[0018] combine figure 2 As shown, the thin lead skin can also be coated on the carbon powder or the carbon rod, or a certain thickness of lead can be cast on the carbon rod, and then...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a lead-coated carbon composite material and its application. Background technique [0002] The existing lead-acid battery plate grid is basically based on an alloy with a high lead content, which is not only heavy in weight, but also high in cost. In practical applications, the general research and development direction is to try to improve the mechanical strength, electrical conductivity and corrosion resistance of the electrode by changing the composition of the lead alloy, but so far, the technology is not yet mature. Contents of the invention [0003] The purpose of the present invention is to solve the above disadvantages, and provide a lead-coated carbon composite material, which is light in weight, good in conductivity and fast in charging speed. [0004] The technical feature of the lead-in-carbon composite material of the present invention is that lead is wr...
