Problems solved by technology

The main reasons for the low specific energy, one is that the reaction efficiency of the active material is less than 50% and the mass is only 40%, and the other is HSO 4 - The ions are restricted by the thickness and material of the plate, and the battery grid and other non-flowing materials account for nearly 40%. The relationship between the active material, the quality of the battery grid, and the electrolyte density is extremely unreasonable. The source of the structural design is to solve the specific mass, specific volume, α, γ coefficient ratio, and the specific energy of the lead-acid battery is difficult to break through

Abstract

The invention discloses a storage battery grid. The storage battery grid comprises a lug or at least one lug hole for installing the lug, wherein the storage battery grid is integrally a polygonal honeycomb structure; the storage battery grid is processed from graphite metal eutectic ceramic, wherein the graphite metal eutectic ceramic comprises conductive agent, ceramic composite material and medium material; the graphite metal eutectic ceramic comprises the following in part by weight: 5-20 parts of conductive agent, 55-70 parts of ceramic composite material, and 5-15 parts of medium material. The storage battery grid is used to substitute a calcium lead alloy storage battery grid in a lead-acid storage battery, and simultaneously substitute a lead metal bus bar, so that the dosage (saved about 50-70%) of heavy metal lead in the lead-acid storage battery is reduced, and lead pollution in the production process of the lead-acid storage battery is relieved. The mass of the storage battery grid is 20% of that of the calcium lead alloy storage battery grid, so that the mass ratio of the polar plate reaction substance to the storage battery grid for carrying and conducting is greatly improved.

Description

technical field [0001] The invention relates to the battery field, in particular to a storage battery grid. Background technique [0002] At present, in the field of lead-acid batteries, the lead-calcium alloy battery grids and metal busbars used contain a large amount of lead, which causes heavy metal lead pollution in the casting, forming, and welding stages. [0003] In addition, the theoretical specific energy of the lead-based active material is 170w.h / kg, which is actually only 1 / 5 of the theoretical specific energy. The main reasons for the low specific energy, one is that the reaction efficiency of the active material is less than 50% and the mass is only 40%, and the other is HSO 4 - The ions are restricted by the thickness and material of the plate, and the battery grid and other non-flowing materials account for nearly 40%. The relationship between the active material, the quality of the battery grid, and the electrolyte density is extremely unreasonable. The s...
