Abstract

The invention relates to the technical field of battery connecting materials, and discloses a battery connecting material and a processing technology thereof. The processing technology comprises the following steps of raw material selection, primary compounding, polishing treatment, annealing treatment, calendering, secondary annealing treatment and secondary compounding. According to the batteryconnecting material processing technology, the principle of plastic deformation of metal and atomic diffusion among the metal is fully utilized, a pure nickel strip, a stainless steel strip and a purecopper strip are calendered and compounded through certain positive pressure and mechanical occlusion to obtain a composite strip, then the composite strip and a pure copper strip are calendered andcompounded to obtain a finished strip, the finished strip can be used as the battery connecting material, the finished strip has excellent conductivity required by the battery connecting material while ensuring good welding performance and strength, and the finished strip can give full play to the use efficiency of a battery.

Description

technical field [0001] The invention relates to the technical field of battery connection materials, in particular to a battery connection material and a processing technology thereof. Background technique [0002] At present, electric tools are more and more widely used, and electric tools need batteries with sufficient power to provide energy to realize the application of electric tools. In order to ensure that the power tool does not have insufficient power supply, open circuit, heat, etc. during use, it is necessary to connect multiple batteries in the power tool stably. At present, the welding effect is good and the widely used materials are NB109 copper alloy, NB109 copper The alloy has good electrical conductivity, excellent welding performance, and strong shock resistance. It is a connecting material with good comprehensive performance; but at the same time, copper alloy also has some obvious shortcomings as a battery connecting material: 1. Copper alloy has good wel...
