The Use of Infrared Lamps, UV LED Lighting and Excimer Irradiation in Lithium Battery Production
Infrared (IR) lamps and ultraviolet (UV) LED lighting are essential technologies in the production of lithium-ion batteries, optimizing processes such as electrode drying, and adhesive curing. The precise application of IR- and UV-radiation enhances process efficiency, energy savings, and increases product reliability.
Infrared (IR) Lamps in Lithium Battery Production
Infrared lamps are widely used as heating boosters to speed up the drying process of electrode coatings. During battery manufacturing, electrodes are coated with active materials that require thorough and gentle drying while at the same time ensuring product performance and longevity. IR lamps provide:
- Compact and Uniform Drying – Featuring a small footprint and homogeneous heating properties, infrared heating system are the perfect addition to a convection oven.
- Fast and energy efficient – Compared to traditional convection ovens, IR lamps reduce drying time and energy consumption.
- Controlled Heating – Precise temperature control prevents material degradation, improving electrode quality.
UV LED Lighting in Lithium Battery Production
UV LED lighting plays a crucial role in curing adhesives, coatings, and sealants used in battery assembly. Key benefits include:
- Rapid and Consistent Curing – UV-curable adhesives and coatings harden almost instantly when exposed to UV light, increasing production speed.
- Lower Heat Emission – Unlike traditional UV lamps, UV LEDs produce minimal heat, preventing thermal damage to sensitive battery components.
- Energy efficiency – UV LEDs can be switched on and off instantly, allowing to save energy when no curing is needed.
Excimer Irradiation in Lithium Battery Production
Excimer VUV irradiation (172 nm) is effective for cleaning, activating, and modifying all types of material surfaces ranging from metal, plastic and glass to electrodes resulting in improved adhesion wettability. Key applications of excimer irradiation in Li-ion battery manufacturing are:
- Battery terminal cleaning – Improves contact resistance by removing organic contaminations before the wire bonding process.
- Cell production – Cleans and modifies electrode and polymer separator surface for better wettability and adhesion.
- Cell to cell bonding – Activation of cell walls before bonding results in better adhesion and firm bonds.
- Cell to frame bonding – Improves bonding between cell wall and frames made of ABS and polycarbonate.
