Abstract
The invention discloses a kind of anode plate grids of external carbon coating, it includes built-in anode plate grid and external coating.The external coating is thick 10~20 μm of carbon material, and carbon material preferred size is nanoscale carbon black or activated carbon or graphite.The present invention forms a kind of protective layer for effectively inhibiting surface corrosion, and significantly improve the charge acceptance and cycle life of lead-acid accumulator by spraying meagre carbon material on anode plate grid surface.
Description
Technical field
The invention belongs to electrochemical cell art fields, in particular it relates to a kind of anode plate grid, especially one
The anode plate grid of the external carbon coating of kind.
Background technique
Anode plate grid built in lead-acid accumulator is metal product, and exposed anode plate grid is conducive to directly connect with lead plaster
Touching, the anode plate grid of such structure are convenient for the proper flow of electronics in lead-acid accumulator charge and discharge process.But lead acid storage battery
Pond use process is substantially exactly a kind of electrochemical reaction process, that is to say, that anode plate grid has the phenomenon that is etched electrochemically.
With lead-acid accumulator continuous service, built-in anode plate grid is gradually corroded, and lead is etched into PbO and PbO2, finally lead
Grid is caused to produce fracture failure.Accordingly, it can be said that with waste lead-acid accumulators and service life, to a certain extent by anode
The operation matter state of grid determines, slows down the corrosion rate of anode plate grid, can improve lead-acid accumulator service life.
Summary of the invention
The problem of being easily corroded present invention is generally directed to anode plate grid built in commercially available lead-acid accumulator proposes a kind of external carbon
The anode plate grid of coating, the structure is simple, be easy to make, conductive capability is good and anti-corrosion capability is strong.
The present invention is achieved through the following technical solutions technical goal.
The anode plate grid of external carbon coating, it includes built-in anode plate grid and external coating.It is theed improvement is that: described
Anode plate grid outer surface is by the external coating that equably spraying thickness is 10~20 μm.
As the scheme of further improvement, the external coating is a kind of carbon material.
As the scheme of further improvement, the external coating is that a kind of granularity is nanoscale carbon black or activated carbon or graphite.
Compared with prior art, the present invention having the positive effect that:
1, the external meagre carbon coating of anode plate grid, structure is simple, forming is easy；
2, the characteristics such as carbon material is conductive good, and high-specific surface area, dense structure, physical and chemical performance are stablized, are made of carbon material
External coating protective action is played to metal anode plate grid, reduce unnecessary corrosion；
3, carbon material is a kind of excellent electric conductor, and external meagre carbon coating further enhances the electric conductivity of anode plate grid, has
Conducive to the charge acceptance and cycle life for improving lead-acid accumulator.
Detailed description of the invention
Fig. 1 is structure of the invention amplification profile schematic diagram.
Specific embodiment
Below according to attached drawing and in conjunction with the embodiments, the invention will be further described.
The anode plate grid of external carbon coating shown in Fig. 1, it includes built-in anode plate grid and external coating.The anode plate grid
By the external coating that equably spraying thickness is 10~20 μm, external coating is a kind of carbon material for outer surface.
Embodiment 1
Anode plate grid outer surface is by equably thick 20 μm of spraying of external coating in the present embodiment, and it is to receive which, which is a kind of granularity,
The carbon black of meter level.
Embodiment 2
Anode plate grid outer surface is by equably thick 15 μm of spraying of external coating in the present embodiment, and it is to receive which, which is a kind of granularity,
The activated carbon of meter level.
Embodiment 3
Anode plate grid outer surface is by equably thick 10 μm of spraying of external coating in the present embodiment, and it is to receive which, which is a kind of granularity,
The graphite of meter level.
The present invention forms one kind and effectively inhibits surface corrosion by spraying meagre carbon material on anode plate grid surface
Protective layer, and significantly improve the charge acceptance and cycle life of lead-acid accumulator.By anode made of above-described embodiment
Grid is respectively installed in conventional lead-acid accumulator, in the case where other conditions are constant, the charging of lead-acid accumulator
3 times or so are improved by ability, cycle life improves 6 times or so.
