Product Details

The Mini Roll-to-Roll Laboratory Coating Machine is professional electrode coating equipment dedicated to lithium battery cathode and anode coating processing. It adopts mature three-roll transfer design composed of metering doctor blade, coating roll and rubber roll, and supports two flexible coating modes: continuous coating and intermittent coating.

Beyond lithium battery electrode slurries, the Mini Roll-to-Roll Laboratory Coating Machine also fits various other slurries and substrate materials perfectly, making it a core device for laboratory process exploration and pilot sample production lines.

Product Features

The Mini Roll-to-Roll Laboratory Coating Machine adopts the same three-roll transfer coating structure as large-scale industrial production lines. All pilot test data obtained from this machine can be directly transferred to mass manufacturing, effectively bridging the technical gap between laboratory R&D and formal production.
The Mini Roll-to-Roll Laboratory Coating Machine realizes seamless switching between continuous coating and intermittent coating processes, which can fully cover all lithium battery positive and negative electrode research scenarios without purchasing extra independent coating equipment.
The coating thickness precision of the Mini Roll-to-Roll Laboratory Coating Machine reaches ≤±5μm. Matched with a high-stability tension control system, it can adapt to ultra-thin copper foil and aluminum foil substrates, ensuring outstanding coating uniformity and highly repeatable experimental data.
The Mini Roll-to-Roll Laboratory Coating Machine has strong compatibility, supporting diverse substrates including plastic films, metal foils and non-woven fabrics, as well as slurries with different viscosity levels. Functional modules such as lamination, heating and corona treatment can be customized to match sample prototyping demands of multiple industries.
The Mini Roll-to-Roll Laboratory Coating Machine adopts a space-saving compact benchtop layout, powered by universal single-phase 220V electricity. It is equipped with a user-friendly touch screen control panel, which can be put into trial use rapidly without any extra auxiliary supporting equipment.
