Description
Technical field
The utility model relates to storage battery, is specifically related to a kind of lead acid accumulator.
Background technology
Lead acid accumulator comprises the parts such as pole plate, barrier film, electrolyte, shell.Wherein, polar plate of lead acid storage battery comprises grid and is coated in coating layer of active substance on grid, and wherein, grid is the supporter of active material, is also the conductor of electric current, and the thickness of its frame has determined the use amount of active material.Because existing grid is planar structure, can only apply the active material of small amount on thinner and light grid, what obtain is thinner pole plate; If need to apply the active material of more amount, must use thicker and heavy grid, what obtain is thicker and heavy pole plate.Therefore, can't obtain thicker and light pole plate by existing thinner and light plane grid, namely can't obtain applying the pole plate of more active material, and then make the weight of lead acid accumulator heavier, gravimetric specific energy is lower.
The utility model content
The purpose of this utility model is exactly the defective for prior art, and a kind of lead acid accumulator is provided.
the technical solution adopted in the utility model is: it comprises the battery cell body, be provided with the battery cover of negative terminal and positive terminal and electrolyte filler port, described battery cell body and battery cover are tightly connected, be provided with by negative plate in described battery cell body, the pole plate group that dividing plate and positive plate are formed by stacking, described negative plate is connected with described negative terminal, described positive plate is connected with described positive terminal, wherein, described negative plate or positive plate are comprised of grid and the active material layer that is coated on grid, described grid comprises substrate, described substrate surface is provided with mesh, described substrate edges is connected with the plate ear, described substrate edges is provided with for the spacing non-conductor frame on substrate of active material layer, described non-conductor frame protrudes from substrate.
Further, described non-conductor frame is comprised of two the non-conductor frames up and down that are arranged on substrate edges, and two of described up and down non-conductor frame protrudes from respectively the upper and lower surface of substrate.
In such scheme, two non-conductor frames are clipped in the middle substrate, and the thickness of two non-conductor frames is according to the size decision of battery designs capacity, and the larger seal ring thickness of capacity is thicker, otherwise thinner.
Grid in the utility model polar plate of lead acid storage battery is set to substrate and the composite grid structure is made in the assembling of non-conductor frame, especially substrate and non-conductor frame organically combine, can realize applying more active material on thinner and light substrate, obtain thicker and plane pole plate light and that capacity is high, not only can reduce the consumption of lead alloy, and then reduce the weight of lead acid accumulator, and can improve the gravimetric specific energy of lead acid accumulator.The use of non-conductor frame has solved to develop or draw in the net the grid of mode moulding and has made and be cut into the unavoidable angular shortcoming in corner after the monolithic pole plate.
