Abstract

The invention relates to the field of lithium ion batteries, and discloses an adapter plate and a lithium ion battery pack with the adapter plate; the adapter plate comprises an insulating substrate; a first tab through hole and a second tab through hole are respectively formed in the insulating substrate; the adapter plate further comprises a first metal component, a second metal component and a third metal component fixed on the surface of the insulating substrate; the first metal component comprises a first metal pipe and a first metal plate extending at the right side of the first metal pipe; the second metal component comprises a second metal pipe, a second metal plate and a third metal plate, wherein the second metal plate and the third metal plate respectively extend at the left and right sides of the second metal pipe; the third metal component comprises a third metal pipe and a fourth metal plate extending at the right side of the third metal pipe; the first metal plate and the second metal plate are just aligned and parallel to each other and respectively positioned at the front and back of the first tab through hole; and the third metal plate and the fourth metal plate are just aligned and parallel to each other and respectively positioned at the front and back of the second tab through hole. The cycle performance of the battery pack is easily increased.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to an adapter plate and a lithium ion battery pack with the adapter plate. Background technique [0002] Lithium-ion batteries are widely used as new energy due to their environmental protection and energy-saving characteristics. At present, the adapter plate used for series connection of lithium-ion battery packs used in vehicle models is made by the method of attaching copper foil to fiberboard, and there are battery packs assembled in series. When the battery passes a large current, the internal resistance of the battery is high, the heat is large, and the overall discharge performance is poor. Contents of the invention [0003] The first object of the embodiments of the present invention is to provide an adapter plate and a lithium-ion battery pack with the adapter plate, which is conducive to improving the cycle performance of the series-connected lithium-ion battery pac...
