Kokam

A key factor in maintaining optimum performance of the cells lies in the temperature control capability. The large surface area and the thin cross-section of Kokam’s ionized aluminum pouch allow much more efficient thermal transfer than cylindrical or thick, plastic coated prismatic cells do. Furthermore, Kokam cells create less heat than standard NMC cells, allowing for more vigorous operations.

The heat dissipation is definitely correlated with safety. Kokam’s approach to safety is very serious and has therefore received various certifications: CE, UL, UN and DNV. Kokam’s efforts to achieve superior reliability and safety has been officially approved through these certifications and various defense qualification tests.

The exceptional cycle life and high discharge rate capabilities of Kokam’s lithium ion battery manufacturing technology are attributable to unique cell manufacturing techniques, such as the Z-folding design, illustrated below. The parallel pairs of electrodes within the cells offer unmatched low internal resistance, which results in less energy loss when charging or discharging in high temperatures.

• Kokam HP: 0.4~0.5mΩ
• The Z-folded stacking and special coating method significantly reduces internal resistance while increasing efficiency, power, and cycle life.

Due to the low internal resistance and optimized design for minimizing energy loss, Kokam’s lithium ion cells have achieved high discharge performance. With their extraordinary discharging characteristics, Kokam’s cells show reliable performance even at a high discharge rate. They are an excellent choice for building up a high-efficiency battery system with their proven performance in various C-rate conditions, resulting in reduction of the total operation cost.
