Cylindrical Li-ion Battery
Cylindrical lithium-ion batteries (such as 18650, 21700) use a wound structure and steel case packaging. They feature mature manufacturing processes, good consistency, high mechanical strength, and relatively good heat dissipation, with built-in safety vents. They are widely used in power tools, electric vehicles, and energy storage systems.
