Flint Begins Scaled Production of Paper-Based Batteries

Flint, a deep-tech startup based in Singapore, has begun manufacturing its rechargeable paper batteries—marking a key shift from research to real-world production. After years of development and lab validation, the company is now producing testable, consistent cells at meaningful volumes, ready for integration into early-stage commercial pilots.

This transition positions Flint to meet a major requirement of its partners: manufacturability. Reliable cell production, supported by quality control and repeatability, is essential before large brands can commit to scaling up battery alternatives in consumer products.

The batteries themselves are built around a cellulose-based architecture and offer key differentiators—rechargeable, PFAS-free, and non-flammable—addressing safety risks associated with lithium-based systems. Flint plans to debut two initial product formats with live demos at CES 2026, with a focus on validating both performance and sustainability claims.

For alternative battery tech, clearing the hurdle of scaled production has often been a roadblock. Flint’s leadership emphasizes that entering manufacturing marks a technical milestone and is a signal that this class of materials is ready to meet industrial standards for cost, consistency, and integration.

Localized Production with Lower Carbon and No Toxic Solvents

Flint’s new 8,000-square-foot facility in Singapore integrates pilot-scale production with R&D and process development, enabling continuous improvement while ramping output. The line is optimized for the company’s proprietary water-based manufacturing method, which avoids toxic solvents and reduces carbon emissions compared to conventional processes.

By designing production around cellulose and limiting use of critical minerals like lithium, cobalt, and nickel, Flint is reducing reliance on geopolitically sensitive supply chains. That choice supports a longer-term strategy to localize manufacturing closer to end markets—discussions are already underway with a major European contract manufacturer to expand capacity and diversify regional supply.

In addition to environmental considerations, Flint’s approach provides greater safety for workers and enables better end-of-life recovery options—areas where traditional lithium-ion and lead-acid batteries still face challenges.
