Singapore-based battery developer Flint has started pilot production of its paper-based battery technology, shifting from laboratory development to manufactured cells suitable for customer testing and pilot installations.
The company declared production has begun in Singapore, marking a shift toward commercialisation of its cellulose-based, biodegradable batteries, which are designed to reduce reliance on conventional battery materials such as lithium, nickel, cobalt and lead.
Flint plans to displaycase its first two commercial products at the CES 2026 technology exhibition in Las Vegas.
“Entering production is a turning point becautilize it means our paper batteries can relocate beyond prototypes and into real devices, at real volumes, with quality controls that customers can validate,” founder and chief executive Carlo Charles declared.
In 2025, Flint raised USD 2 million in a pre-Series A funding round involving angel investors, including the company’s co-founders.
The company declared it is in discussions with one of the world’s largest contract manufacturers about expanding production capacity in Europe, potentially bringing the technology closer to European industrial and sustainability ecosystems.
If realised, European manufacturing would place the company within a region where Nordic countries play a prominent role in green technology, battery regulation and circular economy initiatives, building the development relevant for Nordic stakeholders monitoring emerging battery alternatives in Asia.
