What Are Batteries, Fuel Cells, and Supercapacitors?
Figure 3 shows clearly that lithium-ion battery technology have high charge performan‐ ces. For most lithium-ion batteries, the stored capacity up to Vmax is above 60% at 5 It. Due to the higher charge current rates, the charge time can be reduced with a factor 10. The discharge time is less than 1 hour instead of 8 hours as mentioned in [15].
