Abstract

The invention relates to a high performance battery comprising a battery cover and a battery case; the battery cover comprises a large cover, a small cover and a cover body; the large cover and the small cover are mounted on the cover body; the cover body is connected with the battery case; the top surface is provided with two wiring terminals; the battery case is provided with a plurality of cavities; the inside of each cavity body is provided with a pole group; a plurality of pole groups are connected in series with each other in the cavity of the battery case; the heads and tails are connected to the wiring terminals; the electrolyte is injected in the pole groups; the middle of the large cover is provided with an electricity quantity display; through arranging grids including positivegratings and negative gratings employing Pb-Ca-Sn-AL alloy, the impedance, composition and morphology of the corrosion film formed by Pb-Ca-Sn-AL alloy containing functional additives in sulfuric acidsolution are studied by electrochemical techniques such as AC impedance method, linear potential scanning and electron microscope scanning, and the optimized alloy is used as grid materials.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a high-performance accumulator. Background technique [0002] At present, the hybrid electric vehicle technology has matured, and the market has already started. The hybrid electric vehicle is to change the engine from stopping (that is, idling) to stop the rotation of the engine when the car is stopped for a short time. Although stop or non-stop is a word difference, it reflects the change of the energy consumption of the vehicle, the change of the exhaust gas emitted by the vehicle, and the change of people's concept. [0003] The accumulator of the existing hybrid electric vehicle has a small number of cyclic charging, which in turn affects the receiving capacity of the battery charge, shortens the service life of the accumulator, and has a certain impact on people's use process. [0004] For the above problems, it is necessary to improve it. Contents of the invention ...
