Abstract

The invention discloses a high-capacity battery. The battery comprises a shell, a battery pack arranged in the shell and a heat exchange device arranged outside the shell; the heat exchange device comprises a semiconductor module arranged on the outer side of an upper cover plate of the shell and two same heat dissipation assemblies arranged in the shell, and the condensation ends of the heat dissipation assemblies extend out of the upper cover plate of the shell to be connected to the semiconductor module; and each heat dissipation assembly comprises a conducting bar connected to the positive electrode / negative electrode of the battery pack, a hollow pole column which is connected to the conducting bar and provided with an outer wall groove, and a heat conduction fire extinguishing pipe arranged in the outer wall groove. The reliability, the safety and the service life of the high-capacity lithium ion battery are improved.

Description

technical field [0001] The present application relates to the field of batteries, in particular to a high-capacity lithium-ion battery and an assembly method thereof. Background technique [0002] At present, my country is basically blank in the research and development of large-capacity energy storage batteries, which is mainly limited by factors such as production equipment, safety technology, high scrap rate, and mass production costs. The level of energy storage costs is the key to the development of energy storage systems. In existing lithium battery applications, the use of ultra-large capacity batteries is often involved. At present, the mainstream large-capacity single square lithium battery on the market is 300Ah, and the single cylindrical battery with the largest capacity is not more than 100Ah. Due to the influence of the capacity of the single battery, lithium batteries need to connect multiple single batteries in parallel in energy storage applications. To ach...
