Problems solved by technology

[0002] At present, the grids of all lead-acid batteries use lead alloys, but lead alloys have high resistance, are prone to hydrolysis reactions during charging, have certain self-discharge during storage, have poor creep resistance, and poor deep cycle performance, etc. shortcoming
In addition, due to the relatively high metal density of the currently used lead alloy, 20%-30% of the total mass of the battery is concentrated on the grid, which is not conducive to the improvement of the specific capacity of the battery mass

Abstract

The invention discloses a novel lead-acid storage battery grid. A base body of the battery grid is made of conductive polymeric materials with a lead plating layer prepared on the surface thereof. The novel lead-acid storage battery grid has the advantages that the battery is greatly reduced in weight, output power is improved, and mass specific capacity of the battery is improved; internal resistance of the battery is reduced, conductivity is excellent, flow conductivity of a current collector is improved, distribution of electric current in polar plates is improved, so that utilization rate of electrode active materials is improved; mechanical strength is good, low-temperature performance of the battery is improved, and charge and discharge performance is better; passivation of a negative electrode can be effectively inhibited, so that the assembled battery is good in performance and long in service life; consumption of lead metal is greatly reduced, and environmental pollution and damage to human bodies are greatly reduced. In addition, an original production line is slightly modified, so that cost of investment is low.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage batteries, and in particular relates to battery pole plate technology. Background technique [0002] At present, the grids of all lead-acid batteries use lead alloys, but lead alloys have high resistance, are prone to hydrolysis reactions during charging, have certain self-discharge during storage, have poor creep resistance, and poor deep cycle performance, etc. shortcoming. In addition, due to the relatively high metal density of the currently used lead alloy, 20%-30% of the total mass of the battery is concentrated on the grid, which is not conducive to the improvement of the specific capacity of the battery. Analysis of the structure and composition of the battery shows that the low specific energy of the battery is mainly due to the large amount of inactive material lead (mainly lead-based alloy grid material), so the use of new lightweight grids is becoming more and more important...
