Battery connecting piece with elastic arm fuse function

Abstract

The invention discloses a battery connecting piece with an elastic arm fuse function in the technical field of new energy. The battery connecting piece with an elastic arm fuse function comprises a parallel welding battery core and an overlap welding battery core, wherein the intermediate part of the top of the parallel welding battery core is electrically connected with a first battery core electrical connection piece; the top of the parallel welding battery core is soldered with a parallel welding conductive piece; the front side of the top of the parallel welding conductive piece is electrically connected with four parallel welding bumps; the bottoms of the parallel welding bumps are soldered with the first battery core electrical connection piece; the front side of the top of the overlap welding conductive piece is electrically connected with two overlap welding bumps; the bottom of the overlap welding bumps are welded with the second battery core electrical connection piece; and the top of the each overlap welding bump is electrically connected with an overlap welding electric strike bar. Through combination of the parallel welding conductive piece at the top of the parallel welding battery core and the overlap welding conductive piece at the top of the overlap welding battery core, the battery connecting piece with an elastic arm fuse function improves the safety of the conductive piece while improving the soldering robustness.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a battery connecting sheet with an elastic arm fuse function. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batterie...
