Lead-calcium polar plate for storage battery, and collecting bar welding rod

Abstract

The invention relates to a lead-calcium polar plate for a storage battery, and a collecting bar welding rod. The collecting bar welding rod is characterized by being prepared from the components in percentage by weight: 3.5-4.5 percent of antimony, 0.1-0.4 percent of tin, 0.02-0.08 percent of arsenic and the balance being lead. With the adoption of the collecting bar welding rod, the phenomena of faulty welding and false welding are not easy to occur, the welding quality is good, and the service life of the storage battery is relatively long.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a lead-calcium pole plate of a battery and a bus bar welding electrode. Background technique [0002] Batteries are widely used in the fields of lighting, automobiles, electric vehicles, motorcycles, etc. It mainly includes battery tanks, battery covers and multiple pole groups in the battery tanks. The pole groups include multiple overlapping plates. The positive and negative plates and the separator for separating the positive and negative plates, the top of the positive and negative plates are provided with lugs, and the lugs of the same polarity are connected by bus bar welding, and the grid alloy forming the positive and negative plates has There are many kinds. The grids of ordinary open battery plates are generally cast with lead-antimony alloys, and the grids of maintenance-free battery plates are generally cast with low-antimony alloys or lead-calcium alloys. ...

[0002] Batteries are widely used in the fields of lighting, automobiles, electric vehicles, motorcycles, etc. It mainly includes battery tanks, battery covers and multiple pole groups in the battery tanks. The pole groups include multiple overlapping plates. The positive and negative plates and the separator for separating the positive and negative plates, the top of the positive and negative plates are provided with lugs, and the lugs of the same polarity are connected by bus bar welding, and the grid alloy forming the positive and negative plates has There are many kinds. The grids of ordinary open battery plates are generally cast with lead-antimony alloys, and the grids of maintenance-free battery plates are generally cast with low-antimony alloys or lead-calcium alloys. The positive and negative plates formed of lead-calcium alloy grids and Busbar welding usually uses lead-tin welding rods for welding. When using such electrodes for welding, the lead-tin alloy is easy to stick to the surface of other alloys, that is, during the welding process, the welding rod is easy to stick to the busbar, and the operation rhythm is easily interrupted. In addition, there are many battery specifications, and the thickness and width of the lugs vary greatly, which is more prone to false welding and false welding, and the welding quality is worrying, which affects the service life of the battery
