Problems solved by technology

Gel batteries need to increase the cost by about 1%-2%. The profit of the battery industry is low and the market competition is fierce. Therefore, since the advent of Gel batteries, although they have certain advantages, they have not been able to be promoted.
And although the gel battery has improved the lead-acid battery to a certain extent, it has not fundamentally changed the defects of the lead-acid battery: the disadvantages of large volume, heavy weight, and low mass-to-energy
[0005] The grid of traditional lead-acid batteries is made of lead, which is heavy and pollutes heavily, which limits the development of the battery industry

Abstract

The invention discloses a carbon fiber composite board grid and a preparation method thereof; the carbon fiber composite board grid is molded by pouring carbon fiber composite basic material, wherein the composite basic material is prepared by mixing plastic polypropylene (PP), active polymer polyaniline and carbon fiber according to the weight percent ratio of 45-55wt%: 15-25wt%: 25-35wt%. The carbon fiber composite basic material is adopted to manufacture the board grid instead of alloy lead board grid, so that the weight of a battery is effectively reduced, and the mass ratio energy performance of the battery can be improved; the lead usage quantity is greatly reduced, so that the environmental pollution is reduced; and the invention plays an important role in preventing and governing heavy metal pollution of battery industrial, protecting labor of workers and protecting the environment.

Description

technical field [0001] The invention belongs to the field of accumulators, in particular, the invention relates to a carbon fiber composite grid for lead-acid accumulators and a preparation method thereof, and a carbon fiber composite gel battery containing the carbon fiber composite grid. Background technique [0002] At present, lead-acid batteries used in large quantities on the market use lead as the grid and sulfuric acid as the electrolyte. The use of lead-acid batteries has a history of 150 years. Although lead-acid batteries have the disadvantages of large pollution, large volume, heavy weight, and slow charging; but for other types of batteries, they also have the advantages of low cost, safety, and large capacity. Therefore, lead-acid batteries are still widely used in various industries. [0003] Aiming at the defects of lead-acid batteries, colloidal lead-acid batteries were invented abroad. It is made of fumed silicon dioxide and added with additives to make a...
