Problems solved by technology

Due to the limitation of its structure, the binding force between the current active material of the plate and the grid is not strong, and the active material at the end of use is easy to swell and fall off, which can easily cause the battery plate to be short-circuited and scrapped.

[0039]

[0040] By observing the data in Table 1, it can be seen that the grids made by grid active nano-carbon fibers of the present invention have better corrosion resistance, strength, hardness and other performances than existing Pb-Sb alloy grids. The plate made of the grid has excellent structural strength and dimensional stability.

Abstract

The invention belongs to the technical field of storage batteries, and concretely discloses a grid active nanometer carbon fiber. The grid active nanometer carbon fiber comprises a nanometer carbon fiber body and the cross section of the nanometer carbon fiber body is in triangle shape; the nanometer carbon fiber body comprises a core material and a coating which is fixed on the surface of the core material, the core material is nanometer carbon fiber, and the coating layer comprises a zinc alloy coating material and a composite material; the composite material comprises graphite fiber, polypropylene and silicon nitride. Grids prepared by the grid active nanometer carbon fiber have high strength and high bearing capability, and falling of active substances is avoided.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a grid active nano-carbon fiber. Background technique [0002] One of the most commonly used batteries for storage batteries, its working principle is to use external electrical energy to regenerate internal active materials during charging, store electrical energy as chemical energy, and convert chemical energy into electrical energy output again when it needs to be discharged. [0003] The grid is the main component of the lead-acid battery, accounting for about a quarter of the total mass of the battery. There are three main functions of the grid in the battery: first, as the carrier of the active material, the active material is coated on the grid, The active material is maintained and supported by the grid; second, as a conductor of current, it plays the role of current collection, confluence and transmission; third, it is the current equalization of the plate, so ...
