BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Typically, a device powered by rechargeable batteries includes multiple battery modules to achieve a desired output voltage and/or current. Therefore, the battery modules are combined in series and/or parallel to achieve the desired output voltage and/or desired output current. The battery module includes an array of battery cells stacked together. Conventionally, to hold the array of cells, a plurality of components are used in a mounting assembly, as a result the battery module becomes bulky. Also, there is no provision to provide uniform gap between each adjacent cell. Therefore, during charging and discharging, there is a high tendency of heat generation in the battery cell which results in bulging of the battery cell and thus, the generation of residual stress in the cell.
