Three-Layer Electrode Vacuum Drying Oven – Coating Dryer

What Is an Electrode Vacuum Drying Oven?

An electrode vacuum drying oven is a critical piece of equipment in lithium‑ion battery electrode production. After coating, electrode sheets (anode and cathode) contain residual solvents – NMP for cathode, water for anode – that must be removed to prevent electrolyte decomposition and ensure cell safety. Our vacuum oven lowers the boiling point of these solvents, enabling efficient drying at moderate temperatures (RT‑150°C), preserving electrode integrity and accelerating throughput.

Three-Layer Electrode Drying Oven – Key Technical Features

This three-layer electrode drying oven is designed for high‑throughput battery manufacturing. Key features include:

• Three independent chambers – Each layer (330H×830W×800D mm) can operate with separate temperature, vacuum, and purge profiles – ideal for drying different electrode types simultaneously.

• High vacuum – ≤ -0.095MPa, with 24‑hour vacuum retention ≥95%.

• Precise temperature control – RT‑150°C, accuracy ±0.1°C, uniformity ≤±2.5°C (atmospheric) / ≤±3.5°C (vacuum).

• PLC + touchscreen automation – Programmable heating, vacuum, and nitrogen purge cycles.

• Multi‑layer insulation – Outer wall temperature <45°C, energy efficient.

• Safety – Over‑temperature alarm, pressure interlock, and emergency stop.

The three‑layer design increases throughput by up to 30% compared to single‑layer ovens, making it the standard for high‑volume electrode drying.

Electrode Coating Drying Equipment – Applications & Benefits

As dedicated electrode coating drying equipment, our oven is specifically engineered for post‑coating drying steps:

• Cathode electrode drying – Removes NMP solvent after coating, preventing binder migration and ensuring adhesion.

• Anode electrode drying – Removes water from water‑based slurries, avoiding hydrogen evolution during cell assembly.

• Batch or continuous integration – Shelf trays for cut sheets or roll‑to‑roll compatible fixtures.

Benefits for coating operations:

• Fast drying cycles – Typical drying time 8‑12 hours (depending on electrode thickness).

• Consistent quality – Uniform temperature and vacuum eliminate hot spots and residual solvent gradients.

• Reduced defects – Prevents pinholes, blisters, and binder enrichment at the surface.

• Scalable – Process parameters developed in lab ovens transfer directly to this production unit.
