Kokam Li-ion / Polymer Cell
The Best Partner for your Battery Solution
World Highest Performance Li-ion / Polymer Battery
More Than 16 Years of Battery Technology Experience
Pioneer of Lithium Polymer Battery Technology
Starting from 1998, Kokam has developed and manufactured more than 80 different kinds of Superior Lithium Polymer Battery (SLPB) beginning in 1998. The Superior Lithium Polymer Battery (SLPB) has been proven to deliver superior performance and quality to our customers. Due to the patented cell design, the energy density of the High Energy type SLPB’s is extremely high, while the high power type SLPB’s.
The superior characteristics of Kokam’s Lithium polymer battery are built using Kokam’s distinct manufacturing technology. Marked by the patented Z-folding manufacturing technique and using the most advanced form of Lithium Polymer and thin film laminations, Kokam’s manufacturing technology not only results in a use of and time-efficient manufacturing process, but also enhances the overall performance and quality of the SLPB. During more than 16 years of Lithium polymer battery manufacturing experience, Kokam has brought a variety of cells to the market and range in size from 3.2Ah to 240 Ah.
Advantages of Kokam Lithium Polymer Battery
Features
Kokam set about to solve the limitations associated with conventional lithium-ion technologies, including cycle and calendar life, safety, recharge time, power delivery, and ability to operate in extreme temperatures.The performance of Kokam Lithium polymer battery surpasses the other existing batteries in the market today.
- Heat Dissipation
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 very large surface area and thin cross-section of Kokam’s polymerized aluminum pouch construction allows much more efficient thermal transfer than cylindrical or thick, plastic coated prismatic cells do.
The heat dissipation is also correlated with safety. Kokam’s approach to safety is very serious and has therefore received various certifications such as CE, UL, UN, S-Mark, SBA and KBIA. Kokam’s effort to achieve reliability and safety has been recognized through its certifications in various defense qualification tests.
- Low Internal Resistance
The Kokam Lithium Polymer battery manufacturing technology’s exceptional cycle life and high discharge rate capability are attributable to unique cell construction techniques, such as the Z-fold design, illustrated in above. The cell’s parallel pairs of electrodes offer unmatched low internal resistance, which results in less energy loss in high temperature heat as the cell charges and discharges.
- Kokam UHP: 0.3~0.35mΩ
50% lower Internal Resistance compared to other battery manufacturers
– Z-fold stacking and special coating method significantly reduces internal resistance and increases efficiency, power, and cycle life.
- Increased cycle life
- Heat dissipation
• UHP Cell creates less heat than standard NMC cells, allowing for more vigorous operations
- High Efficiency
Due to the low internal resistance and optimal design for minimizing the loss, Kokam’s Lithium polymer battery has achieved extremely high efficiency rates (>96.5%) @ 0.5C-rate discharge/charge). The high efficiency of Kokam’s cells reduces the total operating cost in a battery system.
• Round Trip Efficiency of NMC cells

- High round trip efficiency (RTE): >95%.
- Long cycle life: 20,000 cycles @ 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 operational conditions.
- The advantages of the LTO cells: Originates from the Anode side of the battery cell. Whereas the Anode side of ordinary Li-Ion cells is made up of Graphite, the Anode side of the LTO cell is composed of LTO.
