Cylindrical lithium ion battery

Cylindrical lithium batteries cell are the most commonly used battery type today. This design allows for better process and technology automation. Cylindrical lithium-ion cells can be produced much faster than prismatic cells. In cylindrical cells, the electrodes are tightly wound and encased in a metal casing, minimizing the possibility of mechanical vibration due to mechanical vibration. The resulting cracking of the electrode material, thermal cycling due to charging and discharging, and mechanical expansion of the internal current conductor due to thermal cycling.
