How Can We Help?
Whether you have a project in mind or just want to learn more about laser solutions for Li-ion cell processing, an IPG laser expert is ready to help.
While traditional foil drying furnaces use fossil fuels and may be up to 100 meters long, laser drying eliminates the fossil fuel consumption carbon footprint and frees up factory floor space and infrastructure. The laser drying process dries over and under the foil surface simultaneously, making it faster and more power efficient than typical convective drying methods.
Laser cutting, also known as laser slitting, is a non-contact process that has the flexibility to cut foils of any shape and is not susceptible to foil edge quality degradations due to die punching tool wear. Using the most reliable nanosecond pulsed lasers in the industry, IPG laser solutions deliver the fastest foil cutting with the highest cut quality.
Compared to alternate technologies where excess mechanical force can create metal fractures, laser welding is a fast, non-contact joining process with consistently high yields. Dual-beam laser welding technology greatly minimizes copper and aluminum welding defects at significantly higher speeds than green or blue wavelength laser alternatives.
Dual-beam lasers create hermetic cap-to-can welds at the high welding speeds that are necessary for large-format prismatic or blade batteries. IPG offers the widest selection of dual-beam laser configurations, enabling real-time dynamic power control of the core and ring beams to perfectly match cell enclosure seal requirements.
Quasi-Continuous Wave lasers minimize heat input using bursts of high peak power to create high-quality injection hole seals at high speeds and use a highly reliable, air-cooled solid state fiber laser design that greatly increases tool uptime.
At IPG, we are dedicated to maximizing productivity and quality in a wide range of E-Mobility applications with cutting-edge laser technologies and solutions including:
