EC-500-18 Extrusion Semi-automatic Battery Coating Machine

The EC-500-18 Extrusion Semi-automatic Battery Coating Machine is designed for precision coating of lithium-ion battery and supercapacitor electrodes in pilot-scale and pre-production environments. Based on the supplied specification, the system supports continuous or intermittent extrusion coating, with an effective coating width of up to 500 mm and a total oven length of 18.6 m. Its process architecture is well suited to researchers and manufacturers seeking improved coating uniformity, scalable process development, and more representative electrode fabrication than small laboratory coaters.

Working principle and coating mechanism

Extrusion coating, often implemented through a slot-die style head in battery manufacturing, meters slurry under controlled flow and deposits it uniformly onto a moving current collector. In semi-automatic production systems, this enables tighter control of coat weight, wet thickness, edge definition, and repeatability than manual casting methods. Continuous and intermittent coating modes are particularly valuable for battery electrode patterning, tab-region control, and pilot-line optimisation. Industrial battery coating platforms in this category commonly integrate unwinding, coating, drying, traction, winding, and electronic control subsystems to maintain tension stability and drying consistency through the line.

Key specifications and features

• Power supply: 380 V, 50 Hz, 3-phase
• Installed power: 150 kW
• Suitable foil thickness: Al foil 10–30 µm; Cu foil 6–30 µm
• Coating roller width: 700 mm
• Effective coating width: 500 mm and below
• Coating mode: continuous / intermittent extrusion coating
• Coating speed: up to 8 m/min, depending on slurry behaviour and process settings
• Air source: 0.6 MPa

These specifications make the TOB-EC-500-18 suitable for electrode slurry systems where drying profile, line speed, and coating uniformity must be balanced for cathode and anode process development.

Typical applications

• Lithium-ion battery cathode and anode coating

• Supercapacitor electrode fabrication

• Pilot-scale battery process development

• Electrode scale-up from laboratory to pre-production

• Process optimisation for slurry rheology, loading, and drying behaviour

Compatibility and workflow integration

This coating machine is suitable for coated aluminium and copper current collectors used in battery research and pilot manufacturing. It can be integrated conceptually with upstream slurry mixing and downstream calendaring, slitting, punching, and cell assembly workflows. For a complete R&D or pilot-line setup, researchers often pair electrode coaters with battery cyclers, potentiostats, glove boxes, vacuum mixers, roller presses, and thickness measurement tools. TOB’s broader product range also includes lab and production-scale battery coating machines, transfer coaters, slot-die coaters, and roll-to-roll systems, which helps users align equipment selection with throughput and coating method requirements.
