18650, 21700, 30700, 4680 and other Li-ions – what''s the difference?
Increasing cell size results in a better ratio of energy-storing versus non-energy storage materials. Using even larger formats such as the 22700, 25700, and 30700 formats is expected to result in a capacity gain per high-energy cell of 1.8 Ah, 3.1 Ah, and 5.8 Ah, respectively, compared to the 18650 (Figure 3) .
