NCR18650GA has specific energy more than 250 Wh/kg and energy density about 700Wh/L. The cell specs help us to build a highly most efficient and extremely balanced battery pack.
NCR20700B is so far the most cost-effective cell created by the Japanese, offering an average of 30% more performance as opposed to its NCR18650GA counterpart while sacrificing just under a 10% increase in size! The internal resistance of this cell is less than 20mΩ. The bigger cells (20,3mm in diameter and 70,3mm long) enabled CMIUTA Electric Company to optimize volumetric energy density into a new pack.
NCR20700A is capable of a continuous discharge of 30 amps with a staggering peak potential of 45 amps, in certain conditions.
These all cells incorporate several electrochemical elements that contribute to their safety. LiNi0.8Co0.15Al0.05O2 is a highly thermally stable cathode material used in lithium-ion batteries. Doping the lithium nickel cobalt oxide with aluminum both stabilizes it’s thermal and charge transfer resistance.
