Abstract

The invention discloses an electric car storage battery ultrathin polar plate, which comprises an insulation protective sleeve and a polar plate core body, the polar plate core body is arranged in the insulation protective sleeve, and is an active matter panel prepared by wire mesh and a filler, the wire mesh is used for dipping and solidifying in the filler, the wire mesh comprises several layers of net structure planes produced by lead alloy wire mesh, and the lead alloy wire meshes arranged between the net structure planes are connected. According to the electric car storage battery ultrathin polar plate, a grid design of common polar plate can be avoided, the wire mesh is used for dipping and solidifying in the filler to prepare the light and thin polar plate core body structure, the electric car storage battery ultrathin polar plate has the advantages of high strength, oxidizability resistance and good conductive performance, the prepared storage battery has the advantages of light weight and little volume, and is suitable for various portable motor-assisted bicycles.

Description

technical field [0001] The invention relates to the field of battery pole plate design, in particular to an ultra-thin pole plate of an electric vehicle battery. Background technique [0002] Electric bicycles are easy to ride, have zero emissions, no pollution to the air, and are energy-saving. They are very popular in the market, and their sales are increasing every year. In the composition of electric bicycles, the cost of batteries is relatively high, and batteries are consumables. Generally, after two to three years of use, the cruising range of ordinary electric bicycles will drop significantly, and new batteries need to be replaced. [0003] There are many types of electric bicycles today, but most of them use lead-acid batteries, because compared with the high quality and high price of lithium batteries, lead-acid batteries are low in cost and cost-effective. Lead-acid batteries rely on the chemical reaction between the plate and the electrolyte to achieve charging,...
