Abstract
The invention discloses a lead-acid battery composite plate grid which is composed of a lead plate grid and a conductive polymer plate grid which are mutually superposed. The invention also discloses a lead-acid battery pole plate which comprises a plate grid and an active material layer coated on the plate grid. The lead-acid battery pole plate is characterized in that the plate grid is the lead-acid battery plate grid. The invention also discloses a lead-acid battery which comprises a pole plate, wherein the pole plate comprises the lead-acid battery plate grid and an active material layer coated on the plate grid. According to the invention, the effective combination of a lead plate grid and a conductive polymer plate grid is realized through the combination of the lead plate grid and the conductive polymer plate grid; and compared with the prior art, according to the invention, the distribution and flow direction of current in a charge-discharge process of a battery are guaranteed, the lead loss is saved, the weight is light, the material cost is reduced, and the market competitiveness is improved.
Description
technical field [0001] The invention relates to the field of storage battery manufacture, in particular to a lead-acid storage battery composite grid, pole plates and batteries. Background technique [0002] At present, lead-acid batteries are widely used in automobiles, trains, tractors, motorcycles, electric vehicles, communications, power stations, power transmission, instrumentation, UPS power supplies, and aircraft, tanks, ships, radar systems and other fields. With the development of the world's energy economy and the improvement of people's living standards, lead-acid batteries have occupied more than 85% of the market share in the use of secondary power sources. [0003] The main part of the battery is the pole plate, and the pole plate is mostly of the paste type, that is, the active material is covered on the grid, rolled by a roller press, heated by a drying kiln, cured and dried to make positive and negative plates, among which, The grid is composed of frame rib...
