Preparation method of positive plate of battery or capacitor

Abstract

The invention relates to a preparation method of positive plate of battery or capacitor, wherein the positive plate is processed by taking a foamed nickel as the matrix, filling the slurry to the plate via a plate automatic production line, baking and cutting the plate. The foamed nickel matrix is initially used in the positive plate type product. The prescription of the positive plate is modified according to the effect of each material so that the capacity of the positive plate and the high-power charge and discharge performance are increased. The invention solves the key problems of long-distance cruising energy storage of each device, big current starting and running.

Description

Technical field [0001] The invention belongs to the field of batteries or capacitors, and particularly relates to a method for preparing positive plates of batteries or capacitors. Background technique [0002] With the gradual advancement of the country's new energy construction, new energy research has entered a rapid development track, especially the research of supercapacitors has attracted the attention of all countries. For battery or capacitor technology, the density of the positive plate formed by the active material has a greater impact on the discharge performance and internal resistance of the battery or capacitor. Although the plate density is too large, the capacity can be increased, but because the amount of electrolyte absorbed is small, the internal resistance is correspondingly increased, and the discharge voltage platform is low, resulting in a decrease in power density; while a plate density that is too small can increase the amount of electrolyte, but Since t...

AI Technical Summary

Problems solved by technology

Although the plate density is too high, the capacity can be increased, but due to the small amount of electrolyte it absorbs, the internal resistance increases accordingly, and the discharge voltage platform is low, resulting in a decrease in power density; while the plate density is too small, although the amount of electrolyte can be increased, but the Due to the reduction of the filling amount of the active material of the plate, the specific capacity of the product cannot meet the design requirements, so it is extremely important to choose the appropriate filling density of the plate and the matrix form of the positive plate
