Let’s Talk About NIR Heaters for Battery Top Sealing

When you’re sealing the top of a battery, you can’t just blast the whole cell with heat. That’s a recipe for disaster. You need something surgical. That’s why we use Near-Infrared (NIR) heaters. By pairing high-purity quartz with halogen filaments, we can hit that sealing film with a burst of energy instantly, leaving the rest of the battery alone.

The Tug-of-War: Speed vs. Lifespan

Here is the tricky part. To keep the internal chemistry safe, you have to seal that film fast. Really fast. To get that kind of speed, you need high-wattage lamps. But there’s a catch: that much intensity puts a lot of stress on the electrodes. If your voltage isn’t steady, those filaments are going to pop way sooner than they should. We’ve built our lamps to handle those little fluctuations, but you still need to make sure your power supply isn’t throwing spikes into the system.
