Abstract

The invention relates to the technical field of batteries, and discloses a graphene plate-type lead-acid battery, which includes a battery case and a top cover, and a plurality of parallel negative plate assemblies are arranged in the battery case, and positive electrodes are arranged between adjacent negative plate assemblies. plate assembly, between the positive plate assembly and the negative plate assembly, and between the outermost negative plate assembly and the inner wall of the battery case, there are microporous separators filled with electrolyte; the positive plate assembly, the negative plate The components all include a microporous ceramic plate and active materials attached to the microporous ceramic plate. The micropores and the outer surface of the microporous ceramic plate are provided with a graphene particle layer; the battery case is located between the negative plate assembly and the positive plate assembly. The upper end is provided with an inner cover plate, the upper ends of the positive plate assembly are electrically connected to the positive plate, and the positive pole is provided on the positive plate, and the upper ends of the negative plate assembly are electrically connected to the negative plate, and the negative pole is provided on the negative pole. The invention has the beneficial effects of stable performance and high charging and discharging efficiency.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a graphene plate type lead-acid accumulator. Background technique [0002] A lead-acid battery usually includes a case, a positive plate, a negative plate, a positive connecting piece, a negative connecting piece, a separator and an electrolyte. The positive plate is usually lead dioxide, the negative plate is lead, the electrolyte is usually sulfuric acid, and the separator is set at Between the positive electrode plate and the negative electrode plate, the separator can prevent the positive electrode plate and the negative electrode plate from contacting and short circuiting. The separator is porous and is used for storing the electrolyte. The current positive and negative plates of lead-acid batteries usually include a plate skeleton (also called a grid) and active materials. The substrate skeleton of the positive and negative plates is usually a lead-antimony-calcium all...
