Flint's Innovative Paper Batteries Begin Production

In a groundbreaking development, Flint, a deep tech company based in Singapore, has officially commenced the production of its sustainable paper batteries. This marks a significant milestone in the energy storage sector, transitioning from laboratory research to tangible, scalable manufacturing. With a commitment to sustainability, these cellulose-based batteries are not only biodegradable but also PFAS-free, representing a revolutionary step toward greener energy solutions.

A Shift in Battery Technology

The announcement made on January 2, 2026, signals a transformative era in battery technology. Flint’s paper battery technology has evolved to a point where it can support pilot deployments and meet customer needs. According to Carlo Charles, the founder and CEO of Flint, entering production is a pivotal moment, as it enables customers to validate the quality and performance of the batteries beyond prototypes.

Flint aims to distribute two battery products that prioritize safety by being non-toxic and designed for safer use, ensuring they are non-flammable and non-explosive. The specifics of these products will be showcased during CES 2026, promising exciting real-world demonstrations.

Cutting-edge Manufacturing Techniques

The production facility in Singapore is tailored specifically for Flint’s unique cellulose-based battery architecture. Utilizing water-based manufacturing methods enhances safety while allowing for scalable output. One of the company’s core missions is to reduce dependency on traditional battery materials like lithium, nickel, cobalt, and lead—elements often criticized for their negative environmental impact.

Purpose-built Facility

Flint has expanded its operations to an impressive 8,000+ square foot manufacturing hub. This state-of-the-art facility is dedicated to refining new processes, scaling production, and conducting ongoing R&D on next-generation battery technologies. The strategic decision to initiate production in Singapore underscores Flint's aim to demonstrate the feasibility of low-carbon battery production closer to end-users, challenging the conventional centralized lithium supply chains that have dominated the industry for too long.

Recognition and Collaborative Endeavors

The momentum gained by Flint throughout 2025 has been significant, beginning with recognition at CES 2025, where the paper battery technology received the Best of CES Sustainability Award. This accolade heightened the company’s visibility and opened doors to new commercial opportunities. Flint’s technology is capturing interest from major players in tech, leading to pilot deployments with renowned companies like Logitech, Amazon Devices, and Dassault Systèmes.

Flint is not only attracting substantial partners but also secured US$2 million in a pre-Series A funding round. This financial backing supports its growth strategy as the company embraces an asset-light model while focusing on fostering innovation.

Future Aspirations and Innovations

As Flint gears up for CES 2026, they intend to publicly unveil their first two commercial paper battery products, demonstrating their applications in real-world contexts. Beyond immediate plans, Flint is also strategizing for expansion beyond Singapore, engaging with one of the largest contract manufacturers in Europe to broaden their manufacturing capabilities and diversify their supply chain.

Further, Flint continues to innovate, developing a solid-state version of its cellulose-based chemistry, aiming for higher-density rechargeable applications. This future technology targets sectors currently served by older lead-acid batteries, promising to redefine what's possible in energy storage solutions.

Collaboration Opportunities

With production in full swing, Flint is embracing collaborations with forward-thinking partners and customers. Initial efforts will prioritize pilot programs and early commercial rollouts. Interested companies looking to innovate within the energy storage space can reach out to Flint for potential collaborations or orders, moving towards a sustainable energy future together.

In conclusion, Flint is not just reinventing batteries; they are reshaping the landscape of energy storage with sustainable, user-friendly innovations. Their commitment to quality, safety, and environmental integrity positions them as a leader in the next generation of battery technology.
