Abstract

The invention relates to a graphite grid storage battery and a preparation method thereof, and belongs to the technical field of storage batteries. The graphite grid storage battery is characterized in that: a positive plate has a positive plate gate structure, and a lead plating layer is compounded on a honeycomb-shaped plate gate framework of the positive plate; and a negative plate has a negative plate gate structure, and a polyaniline conductive coating is arranged on a honeycomb-shaped plate gate framework of the negative plate. The preparation method is characterized by comprising the following steps of: (1) preparing a positive plate gate: performing punch forming and sintering on mixed slurry of graphite and phenol aldehyde resin to prepare the honeycomb-shaped plate gate framework of the positive plate gate; (2) performing lead plating compounding: plating lead powder on the honeycomb-shaped plate gate framework by a spray plating method; (3) preparing a negative plate gate: preparing the honeycomb-shaped plate gate framework of the negative plate gate from an acrylonitrile butadiene styrene (ABS) engineering plastic material through an injection molding process; and (4) spraying the conductive coating: spraying a polyaniline conductive paint on the negative plate gate framework through a spraying method. The graphite grid storage battery has the advantages of light weight, high electrical conductivity, corrosion resistance, low cost, long service life and the like, and is an environment-friendly and economical new generation storage battery.

Description

technical field [0001] The invention belongs to the technical field of accumulators, in particular to a graphite accumulator and a preparation method thereof. Background technique [0002] At present, lead-acid batteries play a positive role in people's production and life, especially in today's increasingly scarce oil resources, the role of lead-acid batteries is becoming more and more obvious. However, due to the technical limitations of the lead-acid battery itself and the use of a large amount of lead and sulfuric acid as raw materials, it will inevitably bring serious pollution to the production environment and the atmospheric environment. Contents of the invention [0003] The invention provides a graphite storage battery and a preparation method thereof to solve the technical problems existing in the known technology. [0004] The invention adopts graphite and conductive plastic materials to produce pole plates and grids of accumulators, pours environment-friendly ...
