Abstract

The invention discloses a high-capacity lithium ion battery which comprises a battery shell, a cover plate arranged on the battery shell, a battery cell group arranged in the shell and a pole connected with the battery cell group, the pole extends out of the cover plate, and the high-capacity lithium ion battery is characterized in that the battery pack comprises a plurality of battery cell units, and a plurality of supporting frames; the supporting frames are used for fixing and pressing the battery cell units; wherein the battery cell units and the supporting frame are arranged at intervals; the battery cell unit is connected with the pole, and the pole is placed in the groove of the supporting frame. According to the high-capacity lithium ion battery disclosed by the invention, the internal temperature of the high-capacity battery is effectively controlled and the safety of the high-capacity battery is improved through the parallel connection and compression of the battery cell units, the fixation of the supporting frames, the addition of a fire-fighting cooling medium or a heat pipe in the hollow pole of the lithium ion battery and the design of tubular pressure relief ports which can be connected in series.

Description

technical field [0001] The present application relates to the field of batteries, in particular to a high-capacity lithium-ion battery. Background technique [0002] At present, the maximum capacity of the lithium battery on the market is 400Ah, while the maximum capacity of the cylindrical battery is no more than 100Ah. Under the background of "carbon peak" and "carbon neutrality", the energy storage industry is expected to make great progress, but it is affected by Influenced by battery capacity, lithium batteries need to be connected in series and parallel with multiple batteries in energy storage applications, resulting in a large number of connection parts, complicated and cumbersome connection steps, and a very large amount of battery management system, wires, and battery boxes. stay high. Contents of the invention [0003] In order to solve the above technical problems, the technical scheme adopted by the application is as follows: [0004] The present application...
