CMIUTA Electric Company designs and assembles battery packs for large unmanned aerial vehicles, drones, or any kind of flying robots, using top-grade cylindrical lithium-ion cells with NCA (LiNiCoAlO2) chemistry, manufactured by Panasonic at former Sanyo Higashiura factory in Hyogo, Japan.
NCR18650GA has specific energy more than 250 Wh/kg and energy density about 700Wh/L. NCR20700B is 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 NCR20700B is less than 20mΩ. The bigger cells (20,3mm in diameter and 70,3mm long) enabled CMEC 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. Battery packs engineered with this cells will help for example, in a fast take-off of the VTOLs type unmanned aircraft, or electric missile.
These all cells incorporate several mechanical elements that contribute to their safety in the CMEC battery packs. LiNi0.8Co0.15Al0.05O2 is a highly thermally stable cathode material used lithium-ion batteries. Doping the lithium nickel cobalt oxide with aluminium both stabilizes it’s thermal and charge transfer resistance.
