ADVANTAGES

SURFACE AND HEAT DISSIPATION

The image below shows the additional surface area and much shorter distance that heat must travel to exit the Kokam pouch cells, as compared to a similar capacity cylindrical cell. The battery cell is the basis of an Energy Storage System. A key factor in maintaining optimum performance is to keep the cell temperature within the designed range. The large surface area and thin cross section of Kokam’s ionized aluminum pouch construction allow much more efficient thermal transfer than cylindrical or thick, plastic coated prismatic cells do.

LOW INTERNAL RESISTANCE

The Kokam lithium ion battery manufacturing technology’s exceptional cycle life and high discharge rate capability are attributable to unique cell construction techniques, such as the Z-folding design, illustrated below. The parallel pairs of electrodes for the cells offer unmatched low internal resistance, which results in less energy loss in high temperature heat as the cells charge and discharge.

 

- Kokam UHP: 0.3~0.4mΩ / Kokam batteries feature noticeably low internal resistance.
- Z-folded stacking and special coating method significantly reduce internal resistance while increasing efficiency, power, and cycle life.

Z-FOLDING TECHNOLOGY

Reduce the Surface side reaction
Decrease internal resistance and keep the material performance

Tab
- Each side of pouch opens under high pressure for safe gas ven

Separator
- Increase the physical strength, Less shrinkage or break down at high temp
- Increase insulation function between cathode and anode

Electrode
- More effective heat dissipation
- No Deformation Core and Good Dimensional Stability

HIGH EFFICIENCY

Due to the low internal resistance and optimal design for minimizing the loss, Kokam’s lithium ion
batteries have achieved high efficiency rates (>95% @ 0.5C-rate discharge/charge).
The high efficiency of Kokam cells reduces the total operating cost in a battery system.
