UNIQUE LITHIUM BATTERY TECHNOLOGY DEVELOPED FOR MILITARY AND COMMERICAL GRADE UAVs Ultra High Energy Compact Battery Solutions UNMANNED AIR SYSTEM / DRONE REALIZATION OF CUSTOMIZED CELLS FOR UAV & OTHER DRONE APPLICATIONS Kokam has successfully designed and manufactured mission-critical battery solutions which are extensively applied to some of the most advanced UAV systems in the field. Kokam’s cells are renowned for their reliability and class-leading energy density. High power output makes Kokam’s cells ideal for both the main propulsion energy source and as backup. Their gravimetric energy density of 260 Wh/Kg greatly exceeds the competition, lowering the overall weight and cross section of the vehicle and allowing extended range and flight time. STRATEGIC ADVANTAGES INCLUDE: - EXTENDED FLYING TIME - VERY HIGH ENERGY DENSITY(~260kWh/kg) FOR MAXIMUM POWER TO WEIGHT RATIO - INHERENTLY SAFE WITH EXCEPTIONAL CYCLE LIFE UAV / DRONE Delair-Tech FT SISTEMAS FT SISTEMAS ULTRA HIGH ENERGY NMC Kokam’s UAV cells are designed for exceptional energy density and safety. Advancements in the Cathode and Anode materials using a high concentration of nickel and C/Si coated graphite respectively. This development, along with Kokam’s unique coating technology enable the creation of the UHE NMC Cell. Category Ultra High Energy NMC Model SLPB080085270 SLPB065070180 SLPB080085270 Capacity Ah 12 27 Weight g 173 385 Energy Density Wh/kg 260 260 Max Charge (A) 12 27 Max Discharge (A) 24 54 Peak Discharge (A) 48 108 W*L*T (mm) 82*183*6.4 97*272*7.6 Current Dimension WELL-VERIFIED AND MARKET LEADING PERFORMANCES IN THE MOST EXTREME WEATHER CONDITIONS In aviation, the reliable performance of batteries is imperative, being able to withstand frequent changes in temperature or other environmental conditions as well as being light-weight. Kokam products meet these requirements and are tested to be fully functional over a wide range of temperature, humidity and pressure.
