Cylindrical Battery Cell

18650/21700

High security. Space-grade safety ensured by multi-level protection, automated manufacturing, comprehensive testing, 24/7 monitoring & big data warning.

Long lifespan. Max 2000-cycle life via modified cathode/anode/electrolyte to slow capacity fade.

High specific energy. Volume energy density >300Wh/kg with advanced materials (high-voltage, cobalt-free, solid-state) and minimalist structure.

Smart combination. High consistency from automated sorting/grouping, avoiding barrel effect to boost pack discharge capacity.

Intelligent management. 24/7 protection via BMS (health monitoring, internal short detection, 90% fire risk reduction) and lifecycle online warning.
