Energy storage battery laser cleaning

What is laser battery cleaning?

Laser battery cleaning is an environmentally-friendly method that does not use chemicals or produce waste products. Additionally, its non-contact nature reduces risk of potential damage to the components and allows for future-proofing of the production process.

Why is laser cleaning important for EV batteries?

Laser cleaning is extremely useful for battery parts that require bonding preparation. Today’s EV manufacturing processes involve an increasing number of adhesives, sealants, pastes, potting components, gap fillers, and encapsulants. They are used to add thermal, structural, sealing and damping features to the battery.

How does laser cleaning work?

Busbars are used to interconnect battery cells or modules. Laser cleaning can effectively remove dirt, oils, and coatings from busbar surfaces, ensuring optimal electrical contact and reducing resistance. This cleaning process helps maintain consistent performance across the battery system and improves overall efficiency.

How does laser cleaning impact the electric vehicle battery manufacturing process?

Laser cleaning is an efficient, non-contact, and environmentally-friendly cleaning method that can significantly increase the quality and performance of most battery products. For our purposes, we will specifically discuss how laser cleaning can impact the electric vehicle battery manufacturing process.

Why should you use laser cleaning for battery cells & busbars?

For instance, laser cleaning for battery cells and busbars can help ensure strong electrical connections between cells and reliability while decreasing the risk of lithium dendrite formation- one of the primary causes of battery failure.

Can laser technology improve the quality of battery cells?

The research conducted at Fraunhofer ILT demonstrates that laser technology can be used as a digital production process to improve the quality of battery cells and significantly increase sustainability during manufacturing. “The next step is to scale up the technology from the prototype to an industrial production line,” says Matthias Trenn.
