Illustration from Scientific Research

A schematic illustration with an in-scale comparison of the size of a typical 21700-type cylindrical cell electrode, a single-layer pouch cell electrode and disk-shaped electrodes for commercially available three-electrode cells (EL-Cell) and 2032 coin cells. For the 21700-type cylindrical cell electrode, the area of only one of the two coated sides is reported, for a better comparison with the other single-side coated electrodes.
