Automatic Vacuum Oven For Lithium Battery

Product Overview

The TOB-SBVO-03AP Automatic Vacuum Oven is a high-performance drying system specifically engineered for the lithium battery manufacturing process, particularly for vacuum drying of electrode sheets and battery materials.

Designed with a focus on industrial production requirements, this equipment integrates vacuum control, temperature regulation, and programmable gas exchange (nitrogen filling) into a fully automated system. Key parameters such as chamber size, vacuum degree, and temperature uniformity are optimized to meet the stringent demands of lithium battery production lines.

With a three-layer independent chamber structure and PLC-based control system, the oven ensures consistent drying results, high process stability, and safe operation under continuous production conditions.

Working Principle

The system operates through a programmable vacuum drying cycle, combining heating, vacuuming, and gas exchange:

• Materials (battery cells or electrode sheets) are placed inside the chamber
• The system performs heating under controlled vacuum conditions
• Periodic nitrogen or dry gas filling cycles are automatically executed
• Moisture and residual solvents are effectively removed
• The system returns to vacuum holding after completion

This automated cycle ensures uniform drying while minimizing oxidation and contamination risks.

Technical Specifications

Core Features

• Integrated PLC control enables automatic execution of heating, vacuuming, and gas exchange cycles without manual intervention.

◉ Three-Layer Independent Control System

Each chamber layer can be independently programmed for:

• Total baking time
• Vacuum time
• Heating time
• Gas filling time
This allows flexible process control for different materials.

◉ High Vacuum Performance

Maintains stable vacuum conditions with:

• Vacuum degree up to -0.1 MPa
• Pressure holding ≥95% over 24 hours

• Uniform Temperature Distribution

• External circulating hot air system ensures:
• Temperature uniformity ≤ ±3.5℃
• Stable thermal environment across all layers

◉ Advanced Safety Protection

• Multi-point over-temperature protection
• Over-pressure detection system
• Automatic alarm and shutdown function
• Real-time fault display on touchscreen
