A lead-acid battery

Abstract

The present invention relates to a lead-acid storage battery, comprising a housing and a pole group, the pole group is installed in the pole group installation groove of the housing, the pole group includes at least 2 single pole groups, the pole group The first single pole group includes a positive plate and a negative plate, the second single pole group includes a positive plate and a negative plate, the positive tabs on the positive plate of the first single pole group are connected through a positive bus bar, and the second single pole group includes a positive plate and a negative plate. The negative tabs on the negative plate of a single pole group are connected through the negative bus bar, the positive bus bar of the first single pole group is connected with the negative bus bar of the second single pole group through the bus bridge connecting piece, and the positive bus bar Or the thickness of the negative electrode busbar gradually increases toward the direction of the cross-bridge connector. The design of the bus bar in the lead-acid storage battery provided by the invention can greatly reduce the amount of lead used in the bus bar and improve production efficiency.

Description

technical field [0001] The present invention relates to lead-acid batteries. Background technique [0002] In view of the proven high performance, low cost, easy recycling and reliable safety of lead-acid batteries, it has been widely used around the world. Lead-acid batteries are an electrode mainly made of lead and active substances. Into, the electrolyte is a battery of sulfuric acid solution. In China, most enterprises have used casting welding machines to weld lead-acid battery pole groups to replace manual welding. When the pole group is welded by a cast welding machine, the structural design of the pole group busbar has a very important influence on the casting and welding quality and production efficiency. However, the busbar structure used in traditional lead-acid cast-welded batteries has a rectangular cross-section and a flat top surface of the busbar, so more lead is used. At present, the price of lead is expensive, how to reduce the use of lead has become the...

Problems solved by technology

The bus bar structure used in traditional lead-acid cast-welded batteries has a rectangular cross-section and a flat top surface of the bus bar, so more lead is used.

At present, the price of lead is expensive, how to reduce the use of lead has become the focus of attention

At the same time, the design of the traditional busbar structure makes the electrode group have a large amount of lead liquid and slow cooling when casting and welding, which not only consumes a lot of lead, but also affects production efficiency.
