Our cells incorporate multiple safety features, including proprietary electrode coatings to prevent dendrite formation, built-in CID (Current Interrupt Device) for overpressure protection, and ceramic separators that withstand high temperatures. Each cell undergoes rigorous testing including nail penetration and overcharge tests.
All cells meet international standards including UN38.3, IEC62619, and UL1642. Our manufacturing process is ISO9001 certified, with complete traceability from raw materials to finished products. Each batch undergoes comprehensive testing including cycle life, internal resistance, and thermal stability assessments.
Under standard conditions (25°C, 80% DoD):
LiFePO4 cells: 3,000-5,000 cycles with ≥80% capacity retention
NMC cells: 1,500-2,000 cycles with ≥80% capacity retention
Actual lifespan depends on operating temperature, discharge rates, and maintenance practices.
