Flint has begun pilot production of its paper battery technology in Singapore, marking a shift from laboratory-scale development to manufactured battery cells suitable for pilot installations and customer testing programmes. The move represents a key milestone for the company as it transitions its technology toward commercial deployment.
Flint is developing cellulose-based, biodegradable batteries designed to reduce reliance on conventional materials such as lithium, nickel, cobalt, and lead. According to the company, entering pilot production enables its batteries to be produced at consistent quality levels and in volumes that can be independently validated by customers. Flint plans to showcase its first two commercial paper battery products at CES 2026 in Las Vegas.
In 2025, the company raised USD2 million in a pre-Series A funding round, including some debt, backed by a group of angel investors, among them Flint’s two co-founders. Alongside its Singapore operations, Flint said it is in discussions with a major global contract manufacturer to potentially expand manufacturing capacity in Europe as it prepares for larger-scale production.
