Detailed Description
26700 50E is a high capacity safety cell of LFP lithium iron phosphate system, with core advantages of 5000mAh ultra-large capacity and high safety of lithium iron phosphate, 3.2V stable voltage, 15.0mΩ internal resistance, 2.5A charging and 10A discharging, focusing on long endurance, suitable for scenarios such as portable energy storage and large/small equipment. High energy density lithium iron phosphate cathode material is adopted, matched with special electrolyte to improve capacity and cycle life. The production adopts fully automatic production line, with strict control of cell quality, 100% full inspection and cycle & safety tests to ensure product stability. Its core competitiveness is the balance between ultra-large capacity and high safety, capacity retention rate over 80% after 1000 cycles, ≤99.0g lightweight suitable for 26700 specification equipment. The application covers energy storage, large portable power supplies, small electric equipment, etc., supporting customized solutions, providing complete technical support.
Safety & Long-Life Series (LFP)
Key Features: Intrinsically safe lithium iron phosphate + optimized SEI film process.
Performance: Ultra-long cycle life of 1,000 cycles (retention rate >80%); no fire or explosion risk during overcharging or over-discharging.
Cutting-Edge Fast-Charging Cold-Resistant Series (Na)
Core Features: Sodium-ion (Prussian Blue/Poly-anion) + Dedicated fast-charging electrolyte.
Performance: Ultra-fast charging (e.g., 19.5A charging), no risk of thermal runaway, excellent low-temperature performance.
