Ultra-thin lead-acid battery plate cluster module

Abstract

The invention discloses an ultra-thin lead-acid battery plate cluster module. The module comprises a starting AGM partition, a finishing AGM partition, a plurality of negative electrode plate grids, afirst AGM partition, positive electrode plate grids, a second AGM partition, a positive electrode fluid paste and a negative electrode paste. The 3D printing method is employed to prepare the lead-acid battery to omit various mechanical devices, obviously improve the efficiency, improve the workshop environment of each manufacturer, have no waste water and waste discharge, and achieve the purposes of environmental protection and energy conservation.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to an ultra-thin lead-acid battery plate cluster module. Background technique [0002] Lead storage battery is a battery system invented by Plant in 1859. It has a history of more than 100 years and is the most widely used chemical power source in the world. Although new batteries such as nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries have been introduced and applied in recent years, lead-acid batteries still rely on high-current discharge performance, stable voltage characteristics, wide temperature range, and large single-cell capacity. A series of advantages such as high safety, abundant and renewable raw materials, and low price occupy a firm position in most traditional fields and some emerging application fields. However, lead-acid batteries have the disadvantages of low energy density and slow charging and discharging. [000...

AI Technical Summary

Problems solved by technology

[0004] Since the current lead-acid battery is forced to thicken the positive and negative plates and solidify the active material in order to ensure the strength of the plates to avoid breakage and the attached lead paste to fall off, and the thickening of the plates will also increase the amount of sulfuric acid injected into the medium. This in turn leads to the thickening of the glass fiber separator and the separator. The thickening of the separator will lead to an increase in the distance between the opposite plates, and the poor activity of the two-pole coating material will cause the conductivity of the plate material to be insufficient.

These are the reasons for the low energy density and slow charging and discharging of lead-acid batteries.

[0005] From the above analysis, it can be seen that the current lead-acid battery processing technology is to process the plate first, dry and solidify it and then assemble it into a battery. It is inevitable that the staff will come into contact with the lead-acid battery during work. Due to the existence of various heavy metal dust, Will be inhaled by the staff, causing occupational diseases
