BHL0870117-13Ah Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. Stable High-Power Output Down to -40℃ Ultra-Wide Temperature Range
Operating temperature: charging 0℃~40℃, discharging -40℃~55℃.
The cell retains ≥95% capacity at 55℃ and delivers full rated capacity at room temperature, while maintaining 95% capacity at 0℃. It reserves over 80% discharge capacity under -40℃ extreme cold conditions with a low-temperature cut-off voltage of 2.3V. No external heating module is required, enabling direct operation of high-power equipment in cold northern regions, cold storage and high-altitude open-air environments. It eliminates integral heating structures and effectively reduces equipment thickness and manufacturing costs.
2. 13Ah Large Capacity & 5C/65A High Rate with 8mm Ultra-Thin Lightweight Design
Featuring an ultra-high energy density of 318Wh/kg, the 13Ah large single-cell capacity significantly extends equipment operating endurance. Adopting an 8mm ultra-thin silver aluminum-plastic pouch structure, it breaks the dimensional limitations of cylindrical cells and can be embedded into the inner cavity of slim high-power devices. The low internal resistance design supports 65A continuous high-current output with stable instantaneous load performance. The peak temperature during charge and discharge is well controlled (≤70℃ during discharge), preventing accelerated cell aging under long-term high-power start-stop operation.
3. Stable Cycle Performance & Low Self-Discharge for Low-Maintenance Long-Term Storage
It maintains more than 80% rated capacity after 600 standard charge-discharge cycles and retains sufficient residual capacity after 30-day full-charge static storage at room temperature with ultra-low self-discharge rate. For long-term storage, a state of charge of 10%~35% is recommended. Stored in dry environments at -20℃~45℃, it only requires simple annual supplementary charging, making it ideal for unattended field high-power energy storage and long-term sealed emergency equipment.
4. Full-Range Strict Safety Verification with Zero Thermal Runaway
The cell has passed comprehensive rigorous tests including overcharge, deep overdischarge, external short circuit, 135℃ thermal shock, high-low temperature alternating cycle, three-axis swept vibration and six-direction drop, with zero fire, liquid leakage or explosion throughout all tests. The high-toughness composite aluminum-plastic film, matched with dedicated protection circuits, provides triple protection against overcharge, overdischarge and overcurrent, fully meeting the safety standards for industrial and cold-region high-power special equipment.
5. Standardized Ultra-Thin Pouch for Efficient PACK Assembly
With unified ultra-thin dimensional specifications, cells from the same batch feature voltage difference ≤20mV, internal resistance difference ≤6mΩ and internal PACK temperature deviation ≤5℃. Only resistance welding and laser welding are permitted, while tin welding is prohibited. Flexible series-parallel configuration requires no customized metal shell molds, enabling rapid mass production for both small-batch and large-batch slim high-capacity energy storage devices.
Ⅱ. Industry Application Scenarios
Cold-Region Large-Capacity Vehicle Parking Energy Storage
Serving as low-temperature backup power for RVs and engineering vehicles. The 13Ah large capacity ensures long-duration power supply, while 5C high-rate current supports vehicle-mounted high-power electrical appliances. The ultra-thin structure saves interior space and delivers stable discharge during static parking in sub-zero environments.
Polar / Plateau High-Power Monitoring Base Stations
Applicable to field high-power meteorological collection equipment and energy storage modules for long-distance oil and gas pipeline inspection. It maintains stable output under extreme day-night temperature differences, and low self-discharge reduces manual inspection and maintenance frequency.
