Abstract
The invention discloses a bipolar storage battery electrode plate which comprises a grid and active substances coated on the grid. The electrode plate is characterized in that the grid is a substratewhich is made of insulating material, wherein both side faces of the substrate are provided with a latticed bar rack, the surface of the substrate is provided with a lead layer, and the periphery of the substrate is fixedly connected with an insulating frame; anode active substances are coated on the surface of the lead layer at one side of the substrate, and cathode active substances are coated on the surface of the lead layer at the other side of the substrate; the substrate is made of ceramic material; and the lead layer is plated on the surface of the substrate. The invention has the advantages that the loaded active substances are not easy to fall off; the area of the grid is large and good for high-current discharge; the grid is made of the ceramic material so as to save a great dealof high-price metal materials; and a nonmetallic material which has light specific gravity is used as a battery conducting frame, thereby lightening the weight of the battery.
Description
Technical field
The present invention relates to lead acid accumulator, relate in particular to the electrode plate structure of lead acid accumulator.
Background technology
Lead acid accumulator from invention in 1860 so far, existing nearly 150 years history, product is with its technical maturity, steady quality has obtained extensive use in the every field of human society.But this product main material is with plumbous, and lead accounts for 80% of product toatl proportion, because of lead metal density 11.3g/cm
3, product weight is big, and specific energy is low to be a shortcoming of this product, so how to improve the major subjects that the gravimetric specific energy of lead acid accumulator is such product research tackling key problem.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of bipolar storage battery electrode plate, and product weight is light, specific energy is high, and saves a large amount of metal material lead.
The present invention is achieved through the following technical solutions:
A kind of bipolar storage battery electrode plate comprises grid, is coated on the active material of grid, and characteristics are that grid is made substrate by insulating material, and the two sides of described substrate are provided with latticed muscle frame, and the surface is provided with lead layer, is fixedly connected with insulating frame around the substrate; Positive active material is coated on substrate one side lead layer surface, and negative electrode active material is coated on the opposite side lead layer surface of substrate.
The further improvement project of the present invention is, described substrate is that ceramic material is made, and lead layer is plated on the surface of substrate.Insulating frame is a plastic material, and it is connected by the injection moulding mode with substrate.
Grid of the present invention is made substrate by the insulating material pottery earlier, plates lead layer on the surface of substrate then, and is associated with the ambroin frame around substrate, therefore can apply positive active material, negative electrode active material respectively in the both side surface of same grid.
Existing routine just, negative plate is separately independently monomer, no matter be that positive plate or negative plate all are made up of the skeleton and the active material of conduction, the conducting matrix grain material mainly is that terne metal is formed, account for 25% ~ 30% of pole plate total weight, account for 10% ~ 15% of battery weight, and bipolar storage battery electrode plate of the present invention, what the skeleton of its conduction adopted is not metal material, and be coated with positive active material respectively two of electric conductor, negative pole utmost point active material, the metallic lead material that the grid of such bipolar plates consumes has only 1% ~ 2% of pole plate weight, accounts for about 0.5% of battery weight.Series connection between the conventional lead-acid battery list lattice need be linked up by plumbous part welding, need to consume the terne metal of battery weight about 2%, cell negative terminal series connection of the present invention is without part, and the electric conductor between the both positive and negative polarity active material has replaced the effect of being connected in series of single compartment.
The present invention has the following advantages:
1. the active material difficult drop-off of the checker of frame structure carrying.
2. the grid surface area is big, helps heavy-current discharge.
3. grid adopts the ceramic material lead plating, saves expensive metal material.
4. adopt nonmetallic materials as the battery conductive skeleton, light specific gravity has alleviated battery weight.
