Abstract

The invention relates to a high-performance storage battery, comprising a battery cover and a battery case; the battery cover includes a large cover, a small cover and a cover body, and the large cover and the small cover are installed on the cover body; the cover body is connected with the battery case; the large cover There are two connecting terminals on the top surface, and several cavities are arranged in the battery case, and an electrode group is arranged in each cavity, and several electrode groups are connected in series in the cavity of the battery case, and the ends are connected with the connecting terminals; Electrolyte is injected; the middle part of the large cover is equipped with a power indicator; the plate Shan is made of Pb-Ca-Sn-AL alloy through setting the positive grid and the negative grid, and adopts AC impedance method, linear potential scanning method and electron microscope scanning. Chemical technology, to study the impedance, composition and morphology of the corrosion film formed by Pb‑Ca‑Sn‑AL alloy containing functional additives in sulfuric acid solution, and optimize the alloy as grid material.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a high-performance storage battery. Background technique [0002] At present, the technology of hybrid electric vehicle has matured and the market has started. Hybrid electric vehicle means that the engine does not stop (that is, idling) when the vehicle is stopped for a short time to stop the rotation of the engine. Stop or stop is a word difference, it reflects the changes in the energy consumption of automobiles, the changes in the amount of exhaust gas emitted by automobiles, and the changes in people's ideas. [0003] The battery of the existing hybrid electric vehicle has few cycle charging times, which affects the receiving ability of the battery for charging, shortens the service life of the battery, and has a certain impact on people's use process. [0004] In view of the above problems, it is necessary to improve it. SUMMARY OF THE INVENTION [0005] In or...
