[0016] Hereinafter, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Referring to Figure 1-2 , an energy storage compatible battery includes a battery module 1. The battery module 1 includes a plurality of single battery cells 3. At least one binding strap 2 is disposed around the outside of the plurality of single battery cells 3. The battery module 1 is assembled by fixing the binding strap 2 on the outside.

[0018] At least one external battery cell 4 is provided on one side of the plurality of single battery cells 3. A foam 6 is provided between the external battery cell 4 and the single battery cells 3. The foam 6 can play a role in fire prevention and heat insulation. At the same time, the foam 6 can absorb glue to fix the external battery cell 4, and the installation is convenient and fast.

[0019] A first end plate 5 is provided on one side of the external battery cell 4. The external battery cell 4, the plurality of single battery cells 3 and the first end plate 5 are all fixed inside the binding strap 2. The binding strap 2 is preferably a metal structure with high strength and good heat conduction performance, which is convenient for heat dissipation and fixing.

[0020] By setting the external battery cell 4 and the foam 6, different sizes of battery modules 1 can be adapted by adding the external battery cell 4. It is possible to add the external battery cell 4 to reach the preset number of battery cells before installation. Different sizes of battery modules 1 can be conveniently produced according to different requirements, without the need to adjust the number of battery cells and then assemble them into the required battery modules 1. The production and installation are convenient and the process is relatively simple.

[0021] An insulating plate 7 is provided on one side of multiple single-cell batteries 3. The insulating component can perform insulation treatment on one side of the battery cell, prevent the occurrence of electric leakage, improve the safety of the battery cell, and the insulating plate 7 is arranged opposite to the external battery cell 4, thereby effectively improving the stability of the battery module 1.

[0022] A second end plate 8 is provided on one side of the insulating plate 7. The second end plate 8 is arranged opposite to the first end plate 5. The first end plate 5 and the second end plate 8 have the same size, and both can provide a tightening force to the single-cell battery 3 from both ends of the battery module 1, improving the temperature performance of the battery module 1.

[0023] Both the insulating plate 7 and the second end plate 8 are located inside the binding band 2. The insulating plate 7 and the second end plate 8 have the same size, so it is not easy to cause the insulating sheet to be knocked and damaged, thereby effectively improving the stability and safety of the battery module 1.

[0024] A collecting plate 9 is provided on the top cover of multiple single-cell batteries 3. The collecting plate 9 is made of a metal structure with high conductivity, preferably aluminum metal material. The collecting plate 9 plays a role in conducting current. It connects the positive and negative electrodes between the single-cell batteries 3, guides the current from the single-cell batteries 3 to the entire battery module 1, and ensures the current balance between the single-cell batteries 3.

[0025] Multiple single-cell batteries 3 are bonded and fixed to each other through a thermally conductive structural adhesive. The thermally conductive structural adhesive can play a role in heat dissipation while bonding and fixing the single-cell batteries 3. The sizes of the single-cell batteries 3 and the external battery cells 4 are the same, making it more convenient and fast to install the external battery cells 4.
