Leakage: max 0.01 vol%/h
Transition cabin: 390 mm

Choosing a Lab or Pilot Line

Xiamen Tmax Battery Equipments (TMAX) builds lab and pilot lines for coin, pouch and cylindrical battery cells: lithium-ion, sodium-ion and solid-state.

A pouch cell line covers three stages: raw material preparation, electrode preparation and cell assembly, from the vacuum mixer and coating machine to electrolyte filling, vacuum sealing and formation. Equipment configurations are customized to research requirements and budget.

Electrode Stage: Mixing, Coating, Calendering, Slitting

The 30 L planetary vacuum mixer prepares slurry with viscosity up to 1,200,000 cP at 15-30 L effective volume. The three-roller transfer coating machine with a comma blade applies a 40-200 μm layer up to 280 mm wide at ±3 μm accuracy and dries it in a 1 m oven.

The hydraulic roller press with 200 mm rollers applies up to 40 t at ±1.5 μm rolling accuracy. The slitting machine cuts electrodes 10-680 mm wide at up to 50 m/min.

Cell Assembly: Stacking, Filling, Sealing, Glove Box

The 200-type automatic stacking machine runs at 1.4-1.5 s per sheet with ±0.3 mm alignment for cells 5-30 mm thick, and a winding machine covers 18650 and 21700 cells. The four-station machine fills 50-1000 g of electrolyte into pouch cells under vacuum and seals them at 6 PPM or more.

The TMAX-FS200 performs the second vacuum sealing with heads up to 250 °C. Assembly takes place in a glove box with water and oxygen below 1 ppm.

About the Manufacturer

Xiamen Tmax Battery Equipments Limited was set up as a manufacturer in 1995 in Xiamen, Fujian, China, and supplies lithium battery equipment and technology. It has around 200,000 square feet of manufacturing facilities and 245 staff.

In October 2026 the TMAX engineering team installed and commissioned a pouch cell pilot line at the Universidad Nacional de La Plata in Argentina; the line produced cells meeting the agreed acceptance criteria.
