Laser welding, cutting, and cleaning are crucial processes in battery production for electric vehicles. Precise and efficient manufacturing technologies are required to ensure the performance, safety, and longevity of batteries. Maxphotonics provides exactly these solutions with its laser technologies and beyond that develops specialized solutions to address challenges such as material processing and process security for a Chinese battery manufacturer.

Batteries are the heart of electric vehicles, serving as energy storage units that supply power for propulsion. Their performance significantly influences the range, efficiency, and longevity of vehicles. High energy density ensures a compact design with maximum storage capacity, while fast charging times and a long lifespan are essential for practical usability.

The production of these high-performance batteries requires pinpoint-accurate and cost-effective manufacturing technologies. Every connection within a battery – whether between cell connectors, electrodes, or casings – and therefore every weld seam must be extremely reliable so that energy losses are minimized, heat generation is controlled, and safety risks such as short circuits or thermal runaway are prevented.

For several years, Maxphotonics has been working with one of China’s leading battery manufacturers, which plays a key role in the global electromobility industry. What began with the supply of laser technologies has now evolved into a strategic partnership. The partner company develops and produces innovative battery systems, energy storage solutions, and industrial applications. In addition to battery manufacturing, it is also one of the largest electric vehicle manufacturers worldwide and actively drives the development of new mobility solutions. Through close collaboration with Maxphotonics, which has designed laser technology specifically for battery production, the company has been able to optimize its manufacturing processes and set new standards for quality and productivity.
