Production kicks off in Singapore as Flint ramps up lower-carbon, cellulose-based batteries and expands pilots with global brands ahead of CES 2026.
SINGAPORE, Jan. 2, 2026 — Flint, the Singapore-based deep tech firm pioneering sustainable, cellulose-based, biodegradable, PFAS-free batteries, today announced that its paper battery technology has entered production, marking the shift from lab-based development to manufactured cells suitable for pilot deployments and customer projects.
With production now active in Singapore, Flint is supplying manufactured battery cells that are rechargeable, non-toxic, and designed for safer use (non-flammable, non-explosive) for customer pilots and early commercial integrations. The company is introducing two battery products to the market, with full product specifics and real-world demonstrations set to be unveiled at CES 2026.
“Redesigning batteries isn’t just about chemistry; it’s about creating something you can manufacture,” said Carlo Charles, Founder and CEO of Flint, who was listed in Forbes’ “30 under 30 Asia 2025” in Industry, Manufacturing & Energy. “Reaching production is a crucial juncture because it means our paper batteries can go beyond prototypes and into actual devices, in real quantities, with quality controls that customers can verify.”
Water-Based Manufacturing Methods in New Facilities
Flint’s production line is specifically constructed around its proprietary cellulose-based battery structure and employs water-based manufacturing methods designed for safety and scalable output. The facility is intended to cut down on dependence on traditional battery materials like lithium, nickel, cobalt, and lead, while enabling lower-carbon manufacturing and enhanced end-of-life alternatives under controlled circumstances.
To support this transition, Flint has expanded into a new facility exceeding 8,000 square feet, which functions as a hub to test new processes, scale up manufacturing, and continue R&D on next-generation battery architectures as the company increases its capacity.
“Opting to start production in Singapore was a deliberate decision,” Charles added. “It demonstrates to the world that there’s a reliable way to make batteries without relying on the long-standing centralized lithium supply chains the industry has depended on. Our technology is meant to be manufactured closer to where products are used, and Singapore provides us with the infrastructure to prove this at production scale.”
2025 Momentum: Recognition, Innovation Partners, and Capital Raise
Flint’s move into production builds on substantial global recognition and commercial progress made in 2025. The year began with Flint’s paper battery technology winning the Best of CES Sustainability Award at CES 2025, boosting global awareness of the company’s approach to safer, lower-carbon energy storage. After the award, Flint saw a rapidly growing commercial pipeline.
Throughout the year, the company further confirmed its technology and market demand by being chosen for several innovation programs and commencing pilot deployments with leading global tech companies, including:
- Logitech: Flint was named a 2025 winner of the Future Positive Technology Challenge and is currently actively testing its technology within specific Logitech device applications.
- Amazon Devices: Flint was chosen for the Climate Tech Accelerator by an MIT initiative, allowing close collaboration on decarbonization efforts across consumer devices like the Kindle and Fire TV.
- Dassault Systèmes: Flint received support via Dassault Systèmes’ 3DEXPERIENCE Lab Ecosystem, accessing advanced design, simulation, and manufacturing scaling tools.
To finance its asset-light growth model, the company also raised $2 million in 2025 in a pre-Series A round, part of which was debt, from a group of angel investors including the two co-founders.
What’s Next: CES 2026, Scale-Up, and Solid-State R&D
Flint will formally launch its first two commercial paper battery products at CES 2026, featuring live demonstrations and real-world customer integrations that showcase the technology’s performance, sustainability, and safety.
Beyond its initial production presence in Singapore, Flint is also getting ready for the next phase of scaling beyond 2026. The company is in active talks with one of the world’s largest contract manufacturers to expand its manufacturing capacity in Europe, including plans to diversify its supply chain.
Simultaneously, Flint continues developing a solid-state version of its cellulose-based chemistry, aiming at higher-density rechargeable applications. This next-generation technology is intended to address markets currently dominated by lead-acid batteries and other legacy energy storage systems.
Doors Are Open for Collaborations and Orders
With production now underway, Flint is beginning to collaborate with selected partners and customers. Initial allocations will prioritize pilot deployments and first commercial launches before broader scaling.
