In this article, research has been done regarding the behaviour of the pouch cell under the action of mechanical abuse, in order to improve pouch battery cells design. Four types of indentations were performed on pouch cell respectively, three-point bending, lateral bending, indentation with hemispherical head and pinch indentation. Contemporary electric vehicles are a solution in terms of environmental pollution, that is why the large vehicle manufacturers also have different models of electric vehicles. Also, a major problem for electric vehicles customers is the autonomy of a vehicle. That forces major electric vehicle manufacturers to invest in in-depth research into storing electricity in energy cells. Li-ion cells seem to be a viable solution at present, and that is why the paper presented a pouch-type cell subjected to specific mechanical stresses. Also, the internal short circuit can be observed in all four tests performed, and its effects are destructive in the case of lithium-ion pouch cells.
