Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, in particular to a punched mesh type negative plate for an energy storage battery. Background Art

[0002] The battery was invented by Plant in 1859 and has a history of over 100 years. Since its invention, lead-acid batteries have always held an absolute advantage among chemical power sources. This is due to their low price, easy availability of raw materials, sufficient reliability in use, suitability for high current discharge, and wide range of ambient temperature.

[0003] The negative electrode plate of the current battery is generally a structure with lead paste coated on the body. Due to the large difference in density between carbon and lead, directly mixing carbon material into the negative electrode lead paste will result in problems such as difficulty in uniform dispersion of carbon material and poor bonding between the lead paste and the plate. The uneven mixing of carbon material and lead powder will affect the stability of the negative electrode paste, and may result in the negative electrode paste not being able to be applied to some parts of the metal substrate when the negative electrode paste is applied to the metal substrate, thereby affecting the final performance of the negative electrode plate. In view of this, we propose a punched mesh energy storage battery negative plate to solve the problems in the above background technology. Utility Model Content

[0026] In this embodiment, both sides of the substrate 1 are fixedly connected with a connecting layer 1 6, the two connecting layers 1 6 are fixedly connected with a conductive layer 2 7, the two conductive layers 2 7 are fixedly connected with a connecting layer 2 8, the two connecting layers 2 8 are fixedly connected with a conductive layer 3 9, the two conductive layers 3 9 are fixedly connected with a connecting layer 3 10, and the two connecting layers 3 10 are fixedly connected with an adsorption layer 11, which can achieve the purpose of increasing the firmness between the conductive layer 1 5, the conductive layer 2 7, the conductive layer 3 9 and the adsorption layer 11, thereby preventing the paste from falling off.

[0027] In this embodiment, the specific structure of the multiple meshes 4 is hexagonal, which can increase the pore size as much as possible, which is conducive to the adhesion of the active material layer on the surface of the substrate 1, increasing the pore size, and increasing the surface area of ​​the substrate 1, thereby facilitating the adhesion of the paste on the surface of the substrate 1.

[0028] In this embodiment, the specific material of the substrate 1 is one of lead, calcium, tin, aluminum, silver, antimony, copper, nickel, and magnesium.

[0032] Working principle: When in use, the multiple meshes 4 on the substrate 1 are all hexagonal honeycomb structures, and the reinforcement ribs on the substrate 1 can not only improve the structural strength of the substrate 1, but also increase the pore size as much as possible, thereby increasing the surface area of ​​the substrate 1, thereby facilitating the adhesion of the paste on the surface of the substrate 1 and achieving the effect of preventing the paste from falling off the substrate 1;
