Carbon plastic composite polar plate grid and preparation method thereof

Abstract

The invention relates to a carbon plastic composite polar plate grid, and belongs to the storage battery technology. The carbon plastic composite polar plate grid comprises an electric-conducting base plate, a support and a tab, wherein the electric-conducting base plate is provided with a plurality of reaction through holes; the outer frame of the electric conducting base plate is provided with a support; the reaction through hoes are provided with lead plaster; the tab is made of lead alloy; the electric-conducting base plate is formed by rolling graphite; and the support is directly subjected to injection molding on the electric-conducting base plate through a mold by ABS (Acrylonitrile Butadiene StyreneAcrylonitrile Butadiene Styrene) engineering plastics. According to the invention, the previous lead alloy material is replaced by graphite, so that the pollution to the environment is reduced; the quality of the battery is improved greatly because of super high conductivity of graphite; because graphite and sulfuric acid can not react, the service life of the battery is prolonged; the preparation process is simple; materials are cheap; resources are rich; cost is saved; the weight of the storage battery is reduced greatly; and thin steel plates added into the electric-conducting base plate which is made of graphite, and the supports in injection molding are used for improving the stability of the electric conducting base plate, and the loss caused by graphite cracking is reduced.

Description

technical field [0001] The invention relates to a grid and a manufacturing method thereof, belonging to the technical field of accumulators, in particular to a structure of a carbon-plastic composite grid and a manufacturing method thereof. Background technique [0002] At present, the role of lead-acid batteries in life and industry is increasing, especially in today's increasingly scarce oil resources, and its role is getting more and more attention from the general public and scientific research groups, but now due to lead-acid batteries Due to its own technical limitations and the use of a large amount of lead, it will inevitably bring serious pollution to the production environment and the atmospheric environment. It has brought a lot of inconvenience for carrying and handling in some workplaces. The Chinese patent ZL 201210043022.7 retrieved from the patent network now discloses a graphite storage battery and its preparation method. It changes the original lead materia...

[0002] At present, the role of lead-acid batteries in life and industry is increasing, especially in today's increasingly scarce oil resources, and its role is getting more and more attention from the general public and scientific research groups, but now due to lead-acid batteries Due to its own technical limitations and the use of a large amount of lead, it will inevitably bring serious pollution to the production environment and the atmospheric environment. It has brought a lot of inconvenience for carrying and handling in some workplaces. The Chinese patent ZL 201210043022.7 retrieved from the patent network now discloses a graphite storage battery and its preparation method. It changes the original lead material of the storage battery grid Composite graphite and structural ABS engineering plastics, which reduces the pollution and weight of lead, but the graphite material of this structure is relatively brittle, easy to break and cause its loss, and the simple composite structure of the grid makes it stable and practical Performance is subject to many restrictions, which indirectly increases the manufacturing cost of its battery, which is not conducive to production and market
