Paper power or paper promise? Comments erupt
Flint Confirms Biodegradable Paper Batteries Are Now in Production
Fans cheer, skeptics cry greenwash, and parents ask: is it safer
TLDR: Flint says its biodegradable paper batteries are now in production for real devices. Commenters are split: some celebrate the safer, non-flammable pitch and big-name pilots, while others cry greenwashing and worry about metals and kid safety, demanding independent proof before crowning paper the new power king.
Flint says its biodegradable, PFAS-free (no “forever chemicals”) paper batteries just left the lab and entered real production in Singapore, promising safer, non-flammable power for everyday gadgets. Cue the comments: Team Hype cheered this as the rare “Better Battery Bulletin,” while Team Suspicious shouted greenwashing and poked holes in the “natural metals” pitch. One skeptic called it “clickbait,” noting the chemistry still uses zinc and magnesium, and that “natural” doesn’t automatically mean better. Fans countered: rechargeable, non-toxic, water-based manufacturing, less reliance on lithium supply chains—what’s not to love?
Then came the parenting panic: “What if a kid swallows one?” asked a commenter, sparking jokes about the “swallow test” and whether paper beats coin-cell danger. Others linked to greenwashing exposé videos like this one, calling for independent studies to prove these batteries truly break down and don’t just linger in landfills dressed as eco-heroes. The crowd’s compromise: show us at CES 2026 with real devices and third-party data. Between excitement over Logitech and MIT pilots and side-eye over biodegradability claims, the vibe is classic internet: hopeful, skeptical, hilarious—paper power or paper promise, the comments are the main event.
Key Points
- •Flint has moved its cellulose-based, biodegradable, PFAS-free paper batteries into production in Singapore.
- •The company will supply select strategic partners and expand pilot programs ahead of CES 2026, where it will reveal two battery products.
- •Flint’s batteries are rechargeable, non-toxic, and designed for safer use, remaining operational when damaged and integrating with existing manufacturing.
- •The production line uses water-based methods to reduce reliance on lithium, nickel, cobalt, and lead, aiming for lower-carbon manufacturing and better end-of-life options.
- •Flint gained 2025 traction: Best of CES Sustainability Award, pilots with global tech firms, Logitech program win, MIT accelerator selection, Dassault Systèmes support, and a US$2M pre-Series A raise.
