The production of lithium-ion battery cells consists of three main process steps: electrode manufacturing, cell assembly, and cell finishing.
Electrode production and cell finishing are largely independent of the type of cell, and in cell assembly, a distinction must be made between soft pack batteries, cylindrical batteries, and prismatic batteries.
Regardless of the battery type, the smallest cell of any lithium-ion battery consists of two electrodes and a separator that separates the electrodes from each other. The ionic conductive electrolyte fills the pores of the electrodes and the remaining space inside the battery
