Low Temperature Shaped Battery

Low Temperature Shaped Battery characteristics

Grepow low temperature shaped battery operating environment in the low-temperature range -40℃ to 50℃. The low-temperature shaped battery is a kind of special battery specially developed by Grepow, to overcome low-temperature defects inherent in the performance of chemical power supply. Grepow low temperature shaped battery adopts innovative design concept, advanced formulation system and materials, rigorous process manufacturing process and method, and overcomes many technical bottlenecks to develop low-temperature lithium battery series.

Why Choose Grepow Low Temperature Shaped Battery?

Grepow low temperature shaped battery can effectively improve the discharge performance of the battery in low temperature environment, reduce the internal resistance of the battery, and achieve the effect of high rate discharge. Therefore, its battery life is longer and its power is stronger. Under low temperature, the capacity of Grepow's low temperature shaped battery still over 80% by 0.2C discharge at -30 °C. This is also one of the core technologies of Grepow, which has the following advantages:

High performance of discharge at low-temperature, the lowest one is able to discharge over 60% efficiency @0.2C at -40℃, and discharge over 80% efficiency @0.2C at 30℃.

Wide operating temperature range, -40 ° C to 50 ° C.

Excellent low temperature cycle performance, charge and discharge by 0.2C at -30 °C , the capacity is maintained above 85% after 300 cycles.

Compared with traditional Li-Polymer batteries, it has broken through the discharge temperature limits of -20℃ to 60℃.

High safety performance, passed UL/CE/UN certification.

Flexible size, battery can be designed according to customer's size.

Able to generate a high current and retain a high capacity at -40℃.

Extendedlowest discharge temperature to -40℃ while retaining its excellent performance.

Can be widely used in cold climates and military products.

With the ability to mass production, the cell consistency is good.
