The application of laser cleaning technology in the new energy industry is gradually deepening. With its advantages of high precision, pollution-free, zero consumables, high efficiency, and ease of automation, it has become a key technology application in battery manufacturing, photovoltaic component maintenance, wind power equipment maintenance, and other areas. In 2024, China's new energy vehicle production and sales grew at an astonishing rate, maintaining its leading position globally for 10 consecutive years. Meanwhile, the installed capacity of photovoltaic and wind power also saw significant growth of 28% and 6%, respectively, highlighting the strong momentum of the green energy transition.
Application of Laser Cleaning Machines in the Entire Process of New Energy Lithium-Ion Battery Manufacturing
- Pre-coating cleaning of electrode sheets: Removing oil stains, oxide layers, and particles from the surfaces of aluminum foil and copper foil ensures uniform coating of electrode materials and prevents the risk of internal short circuits in batteries. Traditional wet cleaning methods may leave residual chemicals, while laser cleaning enables "zero-contact" processing, enhancing electrode consistency.
- Surface treatment before welding: For welding areas such as battery terminals, sealing pins, and busbars, laser cleaning can quickly remove oxide layers and contaminants, enhancing welding strength and reducing the rate of incomplete welds. For example, in the welding of power battery modules, laser cleaning can reduce the rate of welding defects to below 0.1%.
- Battery pack assembly cleaning: Cleaning oxidation layers from battery pack housings, tray welds, and sealant tracks enhances adhesive bonding strength and extends battery pack lifespan.
- Flat wire motor copper wire cleaning: Removing paint layers one by one without damaging the copper wire surface. This precise processing method ensures that the electrical conductivity of the flat copper wire remains unaffected, providing reliable assurance for motor operation.
- Battery repair: Precisely remove the encapsulation material from the surface of aged batteries for recycling.
- Laser cleaning machine maintenance and cleaning of photovoltaic modules
- Photovoltaic glass surface cleaning: Remove dust, bird droppings, organic pollutants, etc., from the surface of photovoltaic glass to improve light transmittance. Traditional cleaning relies on chemical agents or high-pressure water guns, which can damage the glass coating layer, while laser cleaning achieves micron-level precision, protecting the integrity of the coating.
- Frame and bracket treatment: Removes the oxide layer from aluminum alloy frames to prevent corrosion spread and extend bracket lifespan. Enhances subsequent coating or welding effects.
Laser cleaning machine maintenance for wind power equipment
- Blade surface cleaning: Removes dust, oil stains, and biological attachments from blade surfaces to restore aerodynamic performance. Traditional cleaning requires high-altitude work, which is inefficient and poses safety risks, while laser cleaning can be operated remotely using drones or robots.
- Gearbox and bearing degreasing: Laser cleaning can quickly remove oil stains and carbon deposits from gearbox surfaces, reducing maintenance time and improving equipment reliability.
- Tower corrosion protection treatment: Remove oxides from metal surfaces before welding to enhance the adhesion of corrosion-resistant coatings.
- Laser cleaning machine for hydrogen fuel cell surface cleaning
- Bipolar plate treatment: Remove oxide layers and impurities from stainless steel or graphite bipolar plates to improve conductivity and corrosion resistance.
- Membrane electrode assembly (MEA) cleaning: Removes residual particles from the production process to prevent damage to the proton exchange membrane.

- Removal of radioactive contaminants: Laser stripping removes radioactive deposits (such as uranium and plutonium oxides) from metal surfaces infacilities, reducing radiation exposure to personnel.
- Decommissioned equipment processing: Efficiently decomposes the contaminated layer on the surface ofwaste containers for safe recovery.
