Abstract

A spot-welding-free safe capacity expanding device for cylindrical lithium batteries comprises a battery case, and is characterized in that a battery module formed by combining an anode busbar, a cathode busbar and a cylindrical lithium core together is arranged in the battery case, and a battery cap is mounted on the outside of the battery case (12). Holes are formed in the surface of the anode busbar, an anode bus cap is arranged on the surface of the anode busbar, an anode current-guiding clip spring is mounted in the anode bus cap, the anode busbar is provided with bent edges, the surface of the cathode busbar is provided with holes and grasping components, the cathode busbar is provided with bent edges, and the cylindrical lithium core is mounted between the cathode busbar and the anode busbar. The grasping components are four hooks which are matched with a cathode cap of the cylindrical lithium core, a magnet is arranged at the position of each grasping component on the outer side of the cathode busbar, and the magnets are disc-shaped.

Description

technical field [0001] The capacity expansion device relates to a series-parallel capacity expansion device for cylindrical lithium batteries, in particular to a large-capacity, long-life cylindrical lithium battery free of spot welding and a safe capacity expansion device for cylindrical lithium batteries. Background technique [0002] The battery is an energy conversion and storage device. Relatively speaking, lithium batteries have high energy density, small size, no maintenance, and environmental friendliness, and are favored by all walks of life. They are gradually moving from the application of mobile phones and laptops to electric bicycles and electric vehicles. With the advancement of technology and the development of the new energy industry, the industrial development of large-capacity lithium-ion battery technology is very rapid and has become the mainstream of the market. However, technical barriers and costs have always plagued the development of the industry. ...
