We make high-energy-density lithium-ion cells on a silicon-anode design — our commercial platform is SiCore, and the older SiMaxx line is winding down. Think of a standard graphite battery as drip coffee and ours as espresso: same energy, much smaller package. That density roughly doubles a drone's flight time or a light EV's range, and it's the whole product — the reason we're designed into long-endurance aircraft. For those of us keeping score, it's a genuine design edge in a fiercely competitive market, not a material monopoly, and we have to re-win it every design cycle. That's okay.
