Cylindrical cells, 18650 or 21700, are nowadays widely used in commercial, industrial and even in automotive application. Although these cells are standardized and widely used, their design and characteristics differ significantly. Post mortem analyses have shown that difficulties in the operation of devices are caused by the fact that the appropriate cell has not been selected for this application. Evaluation of electrochemical and mechanical properties is therefore obligatory.
