BATTERY JAPAN 2026 was an incredible week in Tokyo. Thank you to everyone who visited our booth and shared your challenges with us. For those we didn’t get to meet, we’d love to continue the conversation here.
At Hyperlum by LEMON Photonics, we believe that small changes in heating can lead to big leaps in battery quality. Our QuantaHeat Laser gives you precise control over thermal fields—space, time, and intensity—so you can tackle the toughest steps in electrode production with confidence.
Here’s how Laser heating help you improve quality and yield across six key battery Anode and Cathode processes:
Pre‑baking
Before coating even begins, a stable anode base matters. Laser pre‑baking shortens dwell time while keeping electrode thickness variation below 1 μm—a small number that makes a big difference in consistency.
Coating Drying
Traditional ovens often cause cracking or binder migration. With laser drying, energy goes directly into the wet coating. The result? Cathodes dry up to eight times faster than convection drying, and anodes three times faster. Cracking is solved, and energy use drops by more than half.
Ceramic Edge Curing
Uneven edges can lead to short circuits or coating defects. Our laser system eliminates edge overheating and miscibility risks, improving coating efficiency by over 60%—so edges come out clean every time.
Tab Heating
Tabs need controlled, repeatable heat for reliable welding. Laser heating is contactless and precise, reducing thermal stress and improving weld strength without damaging sensitive materials.
Roll‑to‑Roll Drying
High‑speed lines demand stability. Laser modules fit seamlessly into continuous production, delivering uniform heat across the web while reducing floor space by up to 80% compared to conventional ovens.
Current Collector Preheating
Aluminum foil is thin and delicate. Laser preheating enhances ductility and toughness, eliminating wrinkles and breakage while cutting energy consumption by more than 50%.
Each of these steps contributes to a larger goal: building batteries that are more reliable, more efficient, and more sustainable.
If you’re exploring ways to increase line speed, reduce energy costs, or simply gain better control over your electrode processes. Whether it’s a technical discussion or a sample test, we’re here to help.
