4. Key Features

Precision Coating

Designed to help achieve uniform electrode slurry distribution and consistent coating quality for laboratory research and process development.

Flexible Coating Configuration

Depending on the selected model, the machine can use slot-die extrusion coating for controlled slurry delivery or doctor blade coating for adjustable wet-film thickness.

Adjustable Coating Parameters

Coating parameters such as coating gap, speed, and slurry delivery can be adjusted according to the machine configuration and experimental requirements.

Laboratory-Scale Design

Suitable for small-batch electrode preparation, material evaluation, and experimental process optimization without requiring a full-scale production line.

Versatile Substrate Compatibility

Designed for use with common battery current collector foils, including aluminum and copper, subject to substrate thickness and machine specifications.

Optional Heating Function

A heating platform or drying module may be available depending on the selected configuration, helping facilitate solvent evaporation and electrode preparation.

5. Working Principle

Slot-Die Extrusion Coating: Battery slurry is delivered through a precision slot-die head and deposited onto the moving substrate. This method is suitable for controlled slurry delivery and repeatable coating processes.

Doctor Blade Coating: Battery slurry is spread across the substrate by a blade with an adjustable coating gap. The wet-film thickness is influenced by the blade gap, slurry properties, coating speed, and other process conditions.

The appropriate coating method depends on the electrode formulation, target coating thickness, substrate, and research objectives.
