2. Why Cylindrical Cells？
Cylindrical lithium-ion cells remain a competitive mainstream format thanks to robust mechanical structure, mature automated manufacturing, outstanding cell consistency and inherent cooling channels after packaging.
Enhanced Structural Safety
Cylindrical lithium-ion cells adopt spiral winding construction. The round shape evenly distributes internal pressure, and rigid metal casing accommodates built-in PTC and CID safety devices to prevent deformation and overheating.
Consistent Performance & Scalable Production
Standard sizes including 18650, 21700 and 4680 etc enable fully automated manufacturing. Superior cell consistency optimises the reliability of battery modules and packs.
Efficient Thermal Management for High-Rate Operation
Natural gaps between cells form cooling channels after assembly, effectively mitigating hot spots under high-rate charging and discharging conditions.
Flexible Modular Integration
Adjustable series-parallel configurations support custom battery pack designs for electric vehicles, e-bikes, power tools and stationary energy storage systems.
Controllable Thermal Propagation Risk
Individual cells carry moderate capacity. Energy released during failure is limited, making thermal runaway easier to contain than large-format prismatic cells.
