35 LITHIUM POLYMER BATTERY : THE RIGHT CHOICE FOR YOUR BUSINESS Kokam works to solve the limitations associated with conventional lithium-ion technologies, including cycle and calender life, safety, recharge time, power delivery and ability to operate in extreme temperatures. The technology s performance features surpass other existing battery capabilities in the market place today. Pouch type has more surface area compared to Prismatic type (High Capacity Cell), providing better heat transfer leading to cooler, longer-life, and higher performance. Prismatic 3.5 x Dissipation Surface Pouch x of heat dissipation 19.1cm/Ah : 11.6 cm/ah x of dissipation surface 650 mm/6.5t : 216 mm/22.5t - Exceptionally High Power Performance - High Energy Density ( ~ 265 Wh/kg) - High Gravimetric and Volumetric Power Density. - Excellent Power-to-Energy Balance - Longer Cycle and Calendar Life - Low Impedance and Heat Generation - Light Weight - No Memory Effect - High Charge / Discharge Energy Efficiency - Low Self-Discharge Rates NMC Cell Cell Specification Capacity (Ah) Voltage Range (V) Cycle life 1C/1C Max Continuous Charge/Discharge LTO Cell Cell Specification Capacity (Ah) Voltage Range (V) Cycle life 1C/1C Max Continuous Charge/Discharge NANO Cell Cell Specification Capacity (Ah) Voltage Range (V) 53Ah 75Ah Remark ~ 4.2 2C/4C ~ 4.2 Over 8,000 cycles 65Ah ~ 2.8 Over 20,000 cycles 46Ah 46 4C/8C 4C/8C 70Ah % DOD End of Life 60% Remaining Capacity Remark 80% DOD Remark 0.2C Cost Life span Cost Life span Cost Life span Energy Performance Energy Performance Energy Performance Power Safety Power Safety Power Safety AIR COOLED BATTERY PACK HIGH POWER NMC Advantages High C-rate up to 12 C-rate discharging performance High C-rate up to 4 C-rate charging performance Improved performance without safety or cycle life trade off LITHIUM TITANATE (LTO) Advantages Operating temperature: -30 ~ 60 degc. High specific power: 4 C-rate continuous and 8 C-rate peak charge & discharge operation High round trip efficiency (RTE): >95%. Long cycle life: 20,000 80% DoD, 1C charge & discharge operating conditions. Extremely Safe: A thermal runaway event is significantly less likely to occur in LTO cells. LTO cells can also be re-operated after an event of an over-discharge, unlike conventional graphite based Li-Ion cells. This feature enables the user to operate the battery cells under extreme environmental and usage conditions. Advantages of the LTO cells: Anode side of ordinary Li-Ion cells are made up of graphite, the anode side of the LTO cell is composed of Lithium Titanate, which has stronger chemical structure than graphite. NMC + LFP+LTO (NANO) Advantages Specially designed for defense & aerospace application This hybrid type cell has incorporated the advantages of NMC, LFP and LTO cells into one cell. It is extremely safe and reliable battery solution for extremely volatile and dynamic operational conditions. The high power, energy and safety features allow the NANO cells to be flexibly applied in various applications. LIQUID COOLED BATTERY PACK Max Continuous Charge/Discharge 3C/8C 3C/8C
