 Lithium-ion batteries are able to store about 80% of the capacity at current rate 2I and LT, sub in GT, T and LT, T.T and LT-sub-sub-GT, with high power cells accepting over 90% of capacity. The efficiency varies between 86% and 98%, with the best values obtained by Poch battery cells ahead of cylindrical and prismatic battery design concepts.
