Novel high-power lead-acid storage battery structure

Abstract

The invention discloses a novel high-power lead-acid storage battery structure which comprises a battery shell, a battery cover and a busbar, the battery cover is buckled at the top end of the battery shell, the busbar is arranged in the battery shell, the battery cover is further provided with a safety valve and a battery pole, an inner cavity of the battery shell is divided into a plurality of partition plates which are vertically arranged, and the partition plates are arranged in the inner cavity of the battery shell. The battery is divided into a plurality of battery grooves in which polar plates are placed, the groove widths of the battery grooves are gradually reduced from top to bottom, and the adopted busbars and butt welding points are arranged in the middle, so that the overall height of a butt welding piece can be reduced under the condition that the length of a conductive path is not increased, the internal space of the battery is fully utilized, and the volumetric specific energy of the battery is improved; the battery jar is designed to be wide at the top and narrow at the bottom, so that the pole group can be conveniently mounted during high-assembly-pressure shell mounting; meanwhile, the pole plate adopts a thick-top and thin-bottom design, so that the uniform assembly pressure is ensured; meanwhile, the design of thick top and thin bottom better conforms to the distribution rule of current in the battery, and the utilization rate of the current is higher when the battery is charged and discharged.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a novel high-power lead-acid battery structure. Background technique [0002] Due to the consideration of battery life, traditional high-power energy storage lead-acid batteries are usually designed with thicker grids, fewer plates, large volume, low specific energy, and limited high-power performance. With the upgrading of customer needs and the rise of lithium-ion energy storage batteries, traditional high-power lead-acid batteries no longer have sufficient market competitiveness. Lead-acid batteries urgently need a technological innovation to improve the high-power discharge performance and specific energy of batteries to keep pace with progress of the past. [0003] Pure lead battery is a new type of lead-acid battery. On the basis of traditional valve-regulated closed lead-acid battery, pure lead battery uses high-purity electrolytic lead to produce grid and lead paste. T...
