Explosion-proof lithium ion battery with low internal resistance and supercapacitor

Abstract

The invention relates to an explosion-proof lithium ion battery with low internal resistance and a supercapacitor. The lithium ion battery and the supercapacitor comprises a housing, individual cells, a heat sink, a plastic insulation sleeve, a top cover and an electrode leading-out screw mechanism. The heat sink is arranged between two adjacent individual cells. A plurality of the individual cells and the heat sink are assembled together to form a cell main body which is arranged in the housing. The plastic insulation sleeve is installed on the upper end of the cell main body. The top cover is arranged on the plastic insulation sleeve at one end of the housing. The electrode leading-out screw mechanism is connected to an electrode leading-out wire through the plastic insulation sleeve and the top cover. One side of the housing is provided with an interface. The explosion-proof lithium ion battery provided by the invention has advantages of simple and reasonable structure, strong shock resistance, low internal resistance loss, long service life, good security and the like.

AI Technical Summary

Problems solved by technology

Most of the structures of ion batteries and supercapacitors currently used in the market are soft-packed polymer lithium-ion batteries and supercapacitors. Lithium-ion batteries and supercapacitors with this structure have certain shortcomings and deficiencies, which are specifically manifested in: ①, Since most of the batteries and supercapacitors were assembled by soldering in the past, the batteries and supercapacitors with this assembly method have weak shock resistance and large internal resistance loss.

② After the pouch battery and supercapacitor are assembled, due to the pouch structure, the ability to resist impact, extrusion and other destructive factors is weak
