Slot Die Coating Machine for Solid-State Battery R&D in Glove Box Operation

Slot Die Coating Machine for Solid-State Battery R&D in Glove Box Operation

Product Overview

The TOB-LVJY-200 single-sided coating slot die coating machine is a compact, high-precision coating system specifically designed for laboratory-scale coating processes and advanced material research. A key advantage of this equipment is its compact structure, enabling operation inside a glove box, making it particularly suitable for solid-state battery research and air-sensitive material processing.

The system integrates a slot die coating head and precision syringe pump feeding system, allowing closed and stable slurry delivery. Through non-contact slot die extrusion coating, the machine ensures high coating accuracy, excellent uniformity, and strong process repeatability.

In addition to lithium-ion battery electrode coating, the equipment is also suitable for applications such as FCCL, optical films, high-end adhesive tapes, and various functional films, making it ideal for laboratory research and pilot-scale process development.

Design and Coating Principle

The TOB-LVJY-200 adopts a slot die extrusion coating method, where slurry is delivered through a precision-controlled slit die and applied onto the substrate without direct mechanical contact. Compared with traditional coating methods, this approach minimizes external disturbances and ensures a stable coating thickness.

The slurry is supplied via a precision syringe pump system, enabling accurate control of flow rate and reducing fluctuations during coating. The entire slurry path operates in a relatively closed environment, which is particularly important for sensitive materials such as sulfide solid electrolytes.

The system also integrates substrate tension control and web guiding (EPC system), ensuring stable substrate transport and precise alignment during coating.

Technical Specifications

Application Scenarios

This equipment is particularly suitable for applications requiring high coating precision and controlled environments, including:

● Solid-state battery electrode coating (inside glove box)

● Lithium-ion battery cathode and anode coating

● Functional film coating (optical films, FCCL, advanced tapes)

● Laboratory-scale coating process development

● Slurry formulation and coating parameter optimization

For solid-state battery research, the ability to operate within a glove box significantly reduces exposure to moisture and oxygen, ensuring material stability and experimental accuracy.

Maintenance Guidelines

● Regularly clean the equipment using a soft cloth with alcohol to maintain surface cleanliness
● Lubricate moving parts to ensure smooth operation
● If not used for an extended period, clean and apply anti-rust oil to exposed mechanical parts
● Periodically check all fasteners (screws, nuts, pins) to prevent loosening and ensure operational safety

Safety Precautions

● Do not place hands or any body parts near moving components during operation
● Only one operator should control the machine at a time to avoid accidental injury
● Unauthorized personnel must not disassemble the equipment
● Ensure proper training before operation
