What Is a Lithium Battery Drying Oven?
A lithium battery drying oven is a critical piece of equipment in lithium‑ion battery manufacturing. It removes residual moisture from electrodes, cells, and other components before electrolyte filling. Moisture can degrade electrolyte, generate harmful gases, and cause capacity fade or safety issues. Our oven uses vacuum technology to lower the boiling point of water, enabling efficient drying at lower temperatures – preserving material integrity.
Battery Vacuum Drying Oven – Key Technical Features
This battery vacuum drying oven incorporates advanced features for reliable, repeatable drying:
High vacuum level – ≤ -0.095MPa, with 24‑hour vacuum retention ≥95%.
Independent 3‑layer chambers – Each layer can operate with separate temperature and vacuum profiles.
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 purge cycles.
Nitrogen purge – Optional for inert atmosphere drying.
Data logging – Each cycle recorded for traceability.
The oven is constructed with 3.0mm 304 stainless steel chambers and multi‑layer insulation to keep outer wall temperature below 45°C.
Electrode Vacuum Drying Oven – Applications & Benefits
As an electrode vacuum drying oven, this equipment is specifically designed for drying coated electrode rolls (anode and cathode) as well as wound or stacked cells before filling. Benefits include:
Removes residual solvent from coating process (NMP for cathode, water for anode).
Prevents electrolyte decomposition – Low moisture content avoids HF formation.
Improves cycle life – Dry electrodes lead to better SEI formation and longer calendar life.
Flexible loading – Shelf trays for electrode sheets, or fixtures for jelly rolls/pouch cells.
The 3‑layer design allows simultaneous drying of different products, increasing throughput by up to 30% compared to single‑layer ovens.
