Problem
Current battery technologies rely on toxic chemicals, are not biodegradable, and have a high carbon footprint, limiting their suitability for sustainable energy storage and creating environmental concerns.
Solution
Flintlabs offers the Flint Paper Battery, a safe and sustainable energy storage solution built from renewable cellulose material. The batteries are leak‑proof, non‑toxic, and fully compostable, delivering a lower carbon footprint than conventional chemistries. They provide up to 4.2 V of power, making them suitable for a range of applications from IoT devices to household electronics. Production began in early 2026, and the technology is designed to scale for both small‑format accessories and larger energy storage systems. Patented designs protect the entire battery architecture, including the anode, cathode, and electrolyte, ensuring consistent performance and safety.
Target Audience
Manufacturers of consumer electronics, IoT device makers, accessory brands, and providers of home energy storage seeking environmentally friendly battery solutions.
