Flint

Why it worked

The video highlights a novel and potentially disruptive technology with clear safety and environmental benefits, presented in a concise and visually engaging manner. The partnership with a well-known brand like Logitech adds credibility and broadens its appeal.

Summary

A Singaporean startup called Flint has developed a "paper battery" using zinc and magnesium dioxide, which is non-flammable, compostable, and cheaper to produce than lithium-ion batteries. They have partnered with Logitech to integrate these batteries into devices, aiming to replace traditional lithium batteries.

Original caption

Singapore-based startup Flint created a "paper battery" that integrates cellulose into the casing, cathode, electrolyte, and separator. Using zinc and manganese dioxide chemistry, the battery contains no lithium, cobalt, nickel, or PFAS, and is non-flammable even when cut or exposed to flame. Founder Carlo Charles says it delivers up to 4.2 volts and 226 watt-hours per kilogram, with 1,000 recharge cycles, rivaling lithium-ion at 1.8 times lower cost per kilowatt-hour. Flint won Logitech's 2025 Future Positive Challenge and is piloting AAA batteries in Logitech peripherals, targeting low-power household electronics rather than electric vehicles.

This new battery doesn't catch fire over a flame and it's even made of paper. A startup in Singapore called Flint created the "paper battery" and they just started production in January. It uses zinc and magnesium dioxide, the same reliable combo found in everyday alkaline batteries. But Flint weaves cellulose that makes paper into every component. There's no lithium, no cobalt, no nickel, and no forever chemicals. That means no toxic mining, no risk of explosion, which are all issues with current battery technology. What's also cool is that it can be flat and bendable, like a sheet of paper or shaped like a regular AA battery. And despite the soft chemistry, it actually delivers up to 4.2 volts, which matches lithium ion with 1,000 recharge cycles. The company says its cost per kilowatt hour is 1.8 times lower than lithium ion, and the battery is fully compostable at the end of its life. Flint has already partnered with Logitech to pilot the batteries in their devices, and the goal is to eventually replace lithium powering everyday electronics around your home. If you want to stay in the loop with the latest in AI and robotics...
