Embodiment 1

[0079] see Figure 1-Figure 4In this embodiment, a stacked large-capacity lithium battery includes a pole 3 and 20 cell bodies 1, and a heat conduction assembly and a cooling / heating assembly are arranged on the pole 3, and the refrigeration / heating assembly passes through the heat conduction assembly Cooling or heating a plurality of cell bodies 1 . There are two poles, namely the positive pole and the negative pole, and each cell body 1 is provided with two tabs 2, which are the positive tab and the negative tab respectively, and the positive poles of the 20 cell bodies 1 The ears are connected in parallel through the positive poles, and the negative pole lugs of the 20 cell bodies 1 are connected in parallel through the negative poles.

[0080] In this embodiment, a protruding conduit 101 is provided on the shell of the cell body 1, and the conduit 101 is arranged on the side of the cell body 1, and the position of the conduit 101 does not conflict with the position of the...

Embodiment 2

[0085] This embodiment is a laminated large-capacity lithium battery, which includes a pole 3 and 30 cell bodies 1, and a heat conduction assembly and a cooling / heating assembly are arranged on the pole 3. Each cell body 1 is used for cooling or heating. There are two poles, namely the positive pole and the negative pole. On each cell body 1, there are two tabs 2, which are the positive tab and the negative tab respectively. The positive poles of the 30 cell bodies 1 The ears are connected in parallel through the positive poles, and the negative pole lugs of the 30 cell bodies 1 are connected in parallel through the negative poles.

[0086] see Figure 5 8 installation grooves 301 are arranged on the positive pole and the negative pole, the eight installation grooves 301 are arranged side by side along the length direction of the positive pole and the negative pole, and the eight installation grooves 301 are arranged on the same side of the positive pole and the negative pole...

Abstract

The invention provides a laminated high-capacity lithium battery, and belongs to the technical field of energy storage batteries. The laminated high-capacity lithium battery comprises a pole and a plurality of battery cell bodies; the plurality of battery cell bodies are connected in parallel through the pole, the pole is provided with a heat conduction assembly and a refrigeration / heating assembly, and the refrigeration / heating assembly refrigerates or heats the plurality of battery cell bodies through the heat conduction assembly. According to the laminated high-capacity lithium battery disclosed by the invention, the refrigeration and heating functions required by the high-capacity lithium battery during working are realized.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries and relates to the technology of large-capacity lithium batteries, in particular to a stacked large-capacity lithium battery. Background technique [0002] At present, the largest capacity square lithium battery on the market is 400Ah. Under the background of "carbon peak" and "carbon neutrality", the energy storage battery industry is developing well. At the same time, the requirements for energy storage battery capacity are getting higher and higher. There are more and more large-capacity energy storage batteries on the market. The larger the capacity of the energy storage battery, the more heat generated inside the battery, which makes it difficult for large-capacity lithium batteries to dissipate heat. Batteries used in large environments need to be heated in order to ensure normal startup and operation of the batteries. Therefore, simultaneous heat dissipation and cooling for...
