PKNERGY Wide Temperature Battery
As energy demand increases, we’ve found that traditional lithium batteries struggle to meet the needs of environments with large day-to-night temperature differences, such as deserts. PKNERGY has overcome the battery temperature limit through its innovative aluminum-based cathode patent, developing a wide-temperature range LFP cell that operates from -70°C to 80°C.
Working temperature range-50~80°C
Max discharge rate:7C
-10°C charge and discharge cycle life>800 cycles
Flexible & Wide Applications
PKNERGY wide temperature battery technology can be applied to lithium polymer batteries, cylindrical batteries, and prismatic batteries, giving highly adaptable batteries to products in different usage scenarios. If you have any questions or ideas, contact PKNERGY and make it happen!
Aluminum-Based Anode Battery Cells
PKNERGY’s unique aluminum-based anode battery cells replace the traditional graphite anodes and electrolyte used in lithium-ion batteries, enabling the wide-temperature batteries to maintain 70% discharge capacity even in extreme cold weather at -70°C. In high-temperature environments, the batteries perform exceptionally well, with a discharge capacity retention of 99% at 80°C—far surpassing the performance of existing lithium battery solutions.
Wide temperature battery VS. lithium battery
| Comparison Dimension | Wide temperature battery | Standard Lithium Battery | Advantage |
|---|---|---|---|
| Operating Temperature Range | Charging: -30°C to 60°C Discharging: -50°C to 80°C |
Charging: 0°C to 45°C Discharging: -20°C to 60°C |
Stable operation in extreme cold and high-temperature environments, ideal for demanding conditions. |
| Low-Temperature Charging/Discharging Performance | Supports 400mA charging at -20°C Supports 1000mA discharging at -40°C |
Significant performance drop or non-functional below -10°C | Efficient performance in extreme cold, ensuring reliable operation in low-temperature regions. |
| Fast Discharge Capability | Supports 14.0A fast discharge | Typically supports less than 10A fast discharge | Meets high power demand for devices like power tools and high-performance equipment. |
| Cycle Life | Low temperature (-10°C): 800 cycles Room temperature (25°C): 1000 cycles |
Typically less than 500 cycles under deep discharge | Longer lifespan under extreme conditions, reducing replacement frequency and saving costs. |
| Internal Resistance | Less than 30mΩ | Higher internal resistance, leading to performance drop due to heat | More stable and efficient operation, suitable for long-term high-load usage. |
| Application Scenarios | Outdoor equipment in extreme cold or heat Industrial equipment Military and aerospace New energy storage systems |
Limited to devices operating in normal temperatures | Broader application range, covering more demanding scenarios. |
