SJR-18650 Cylindrical Cell Semi-automatic Winding Machine

Semi-Automatic Cylindrical Cell Winding for Battery R&D and Pilot Production

The 18650/21700 Cylindrical Cell Semi-Automatic Winding Machine is designed for precision winding of cylindrical lithium-ion battery cores used in laboratory development, pilot-scale manufacturing, and process optimisation. In operation, the cathode and anode electrodes are manually introduced into the winding section with the separator, after which the machine performs controlled winding, automatic tape termination, needle change, and unloading of the finished jelly roll. This semi-automatic approach gives researchers strong process control while improving repeatability compared with manual winding.

Applications and Research Value

This system is well suited to lithium-ion battery research groups working on cylindrical cell prototyping, electrode formulation studies, separator optimisation, and small-batch pre-production. It integrates naturally with related ScienceGears categories such as electrode coating and slitting equipment, tab welding systems, electrolyte filling tools, vacuum sealing equipment, and battery cyclers or test stations. For researchers in Australia and New Zealand, ScienceGears adds value through local technical guidance, fit-for-purpose equipment selection, and support across the broader battery research workflow.
