BHL0670117-10Ah Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. Stable Full-Range Discharge 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% capacity under -40℃ extreme cold conditions with a low-temperature cut-off voltage of 2.75V. No external heating module is required, enabling direct high-power operation of outdoor equipment in cold northern regions, cold storage and high-altitude areas. It effectively reduces structural costs and overall thickness of end devices.
2. 10Ah Ultra-Large Capacity & Ultra-Thin Flexible Pouch Structure
The high-capacity pouch design greatly improves equipment endurance within the same installation space. Adopting flexible aluminum-plastic film packaging, the cell features a lightweight slim profile without the dimensional limitations of rigid cylindrical steel shells, perfectly fitting narrow equipment cavities. It achieves excellent temperature control during high-power discharge, with surface temperature lower than 60℃ during charging and ≤70℃ during discharging. It resists aging under frequent start-stop operation, satisfying both long-duration runtime and instantaneous high-power output requirements.。
3. Stable Cycle Performance & Low Self-Discharge for Maintenance-Free Long-Term Storage
It maintains more than 80% rated capacity after 500 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 supplementary charging once a year, making it ideal for unattended field equipment and long-term sealed emergency devices.
4. Comprehensive Strict Safety Tests with Zero Thermal Runaway
The cell has passed full abuse tests including overcharge, deep overdischarge, external short circuit, 135℃ thermal shock, high-low temperature alternation, three-axis swept vibration and six-direction drop, with no fire, liquid leakage or explosion occurring throughout all tests. The deformable flexible composite film, combined with dedicated protection circuits, provides triple safeguards against overcharge, overdischarge and overcurrent, complying with safety standards for industrial and special field equipment.
5. Standardized Pouch Design for High Compatibility PACK Assembly
Featuring a fixed ultra-thin specification, the flexible aluminum-plastic pouch adapts to diverse equipment structures. Cells from the same batch deliver 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 molds, significantly improving mass production efficiency for small-batch lightweight devices.
Ⅱ. Industry Application Scenarios
Cold-Region High-Power Individual Equipment
Suitable for winter rescue high-power lighting, cold-resistant wearable power modules and field emergency starting power supplies. The ultra-thin pouch structure fits closely to equipment profiles, delivering stable high-power output at -40℃ and extending endurance for outdoor field missions.
Ultra-Thin Monitoring Instruments for Cold Storage & Plateaus
Ideal for pipeline inspection recorders, portable cold storage detectors and high-altitude meteorological collection terminals. Low self-discharge reduces manual maintenance frequency, ensuring stable operation under drastic day-night temperature differences.
Vehicle-Mounted Ultra-Thin Low-Temperature Energy Storage
Applied to large-capacity RV parking power supplies and backup power modules for engineering equipment. It provides stable high-power output for vehicles parked in extreme cold conditions, while the slim lightweight design saves internal vehicle space.
