BHL18650-2200-UHT Ultra-High Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. Extreme High-Temperature Resistance, Stable Discharge Up to 150℃
Operating temperature limits: charging 0℃~40℃, discharging 0℃~150℃.
The cell retains ≥95% capacity at 55℃ and maintains no less than 90% rated capacity under 150℃ extreme high-temperature conditions, with a high-temperature discharge cut-off voltage of 2.75V. Adopting a specialized high-temperature electrolyte system, it requires no additional heat dissipation structures. It is perfectly adaptable to downhole equipment, metallurgical devices, high-temperature inspection instruments and outdoor sun-exposed equipment, effectively reducing overall thermal design costs.
2. Long Cycle Life & Low Self-Discharge for Maintenance-Free Long-Term Storage
The cell maintains over 80% rated capacity after 1500 charge-discharge cycles under standard working conditions and retains sufficient residual capacity after 30-day full-charge static storage at room temperature with ultra-low self-discharge performance. A 10%~35% state of charge is recommended for long-term storage, requiring only regular supplementary charging in dry environments. It is ideal for unattended monitoring devices in high-temperature areas, lowering frequent maintenance and cell replacement costs.
3. Full-Range Safety Certification with Zero Thermal Runaway Under High Temperatures
The cell has passed comprehensive safety tests including overcharge, overdischarge, external short circuit, 135℃ thermal shock, high-low temperature alternation, three-axis vibration and six-direction drop, with zero fire or explosion throughout all tests. The integrated steel shell resists high-temperature extrusion. The cell surface temperature is controlled below 60℃ during charging and ≤70℃ during discharge. Equipped with professional protection circuits, it provides triple protection against overcharge, overdischarge and overcurrent, meeting high safety standards for high-temperature industrial equipment.
4. Superior Weather Resistance & Anti-Aging Performance for Complex High-Temperature Conditions
After continuous 10~55Hz three-axis vibration, high-low temperature damp-heat cycling and 1-meter six-direction drop tests, the cell shows no deformation or damage and retains over 95% capacity. The customized purple high-temperature aging-resistant sleeve features UV resistance, moisture proofing and anti-corrosion properties. Cells in the same pack deliver voltage difference ≤20mV, internal resistance difference ≤6mΩ and internal pack temperature deviation ≤5℃, avoiding local overheating and capacity attenuation in high-temperature environments.
5. Standard Universal Specification for Efficient Bulk PACK Assembly
Adopting universal standard 18650 dimensions, the cell is safely packaged with 100 pieces per inner box and 200 pieces per outer box with shockproof and anti-collision protection for transportation. Only resistance welding and laser welding are permitted, while tin welding is prohibited. It supports flexible series-parallel configuration, and fuses can be installed in series loops for enhanced safety. The battery pack can be designed with waterproof, anti-static and leak-proof structures; slight liquid leakage will not erode the protection circuit board. No customized molds are required, ensuring high-efficiency mass production.
