BHL0870117-13Ah Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. Stable High-Power Output Across -40℃ Ultra-Wide Temperature Range
Operating temperature: charging 0℃~40℃, discharging -40℃~55℃.
The cell maintains ≥95% capacity at 55℃ and full rated capacity at room temperature, while retaining 95% capacity at 0℃ and over 80% capacity at -40℃ extreme cold, with a low-temperature discharge cut-off voltage of 2.3V. No external heating module is required, enabling direct and stable operation of high-power equipment in cold northern regions, cold storage facilities and high-altitude open-air scenarios. It eliminates additional 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-capacity design greatly extends equipment operating endurance. Adopting an 8mm ultra-thin silver aluminum-plastic pouch structure, it breaks the dimensional limitations of conventional cylindrical cells and fits perfectly into the compact cavities of slim high-power devices. The low internal resistance design supports continuous 65A high-current output with stable instantaneous load performance. The peak temperature during discharge is controlled within 70℃, effectively preventing accelerated aging under long-term high-power start-stop operation.
3. Reliable Cycle Performance & Low Self-Discharge for Low-Maintenance Long-Term Storage
The cell retains over 80% of its rated capacity after 600 standard charge-discharge cycles and maintains sufficient residual capacity after 30-day full-charge static storage at room temperature with ultra-low self-discharge. For long-term storage, a state of charge of 10%~35% is recommended. When stored in dry environments at -20℃~45℃, it only requires simple supplementary charging annually, making it ideal for unattended high-power field 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. No fire, liquid leakage or explosion occurs during all tests. The high-toughness composite aluminum-plastic film, paired with professional protection circuits, provides triple protection against overcharge, overdischarge and overcurrent, fully complying with safety standards for industrial and cold-region high-power special equipment.
5. Standardized Ultra-Thin Pouch Structure for Efficient PACK Assembly
With unified ultra-thin dimensional specifications, cells from the same batch achieve 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, supporting 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
Serves as low-temperature backup power for RVs and engineering vehicles. The 13Ah large capacity delivers long-lasting power supply, while 5C high-rate current supports vehicle-mounted high-power electrical appliances.
