Laser Cleaning Of Battery Casing To Remove Oxide Layer
Aug 12, 2026
Most electric vehicle battery casings are made of aluminum alloy due to its lightweight and excellent thermal conductivity. However, aluminum surfaces are prone to oxide layers, oil stains, and processing residues during manufacturing.
SDQY LASER provides laser cleaning solutions for battery casing surfaces, helping battery manufacturers achieve efficient oxide removal, improved surface quality, and environmentally friendly production.
Traditional cleaning methods
1. Chemical Cleaning: Chemical solutions can effectively remove contaminants, but they generate wastewater and chemical waste, increasing environmental pressure and treatment costs.
2. Mechanical Grinding: Grinding and abrasive cleaning require physical contact with the workpiece, which can lead to: surface scratches, material deformation, and uneven surface roughness. For precision battery manufacturing, these drawbacks affect product consistency and production efficiency.
How Laser Cleaning Removes Oxide Layers from Battery Casings
SDQY LASER laser cleaning machines utilize high-energy laser pulses to precisely target contaminants and oxide layers on the battery casing surface.
When the laser beam irradiates the oxide layer, the contaminants absorb the laser energy and rapidly expand, generating a plasma effect and shock waves. These physical effects can break down and remove unwanted oxide layers without damaging the underlying aluminum substrate.
Key Advantages of Laser Cleaning for Lithium-ion Battery Casings
* No mechanical contact – Prevents scratches and deformation of the battery casing
* No consumables required – No abrasives or chemical reagents needed
* High-precision cleaning – Removes oxide layers while protecting the substrate
* Consistent surface quality – Uniform cleaning for improved performance
* Environmentally friendly operation – No wastewater or chemical residues
