Flint secures $2M for cellulose-based paper batteries
Flint, a deep-tech startup based in Singapore specializing in cellulose-based paper batteries, has raised $2 million in seed funding to accelerate the commercialization of its sustainable energy storage solutions. The funding round, led by a consortium of international angel investors and AI-driven venture capital firm Hatcher+, will support pilot production, intellectual property development, and expansion into global markets. Flint’s paper batteries, made from natural and compostable materials like cellulose, zinc, and manganese, offer a sustainable, safe, durable, and cost-efficient alternative to conventional batteries. Flint is targeting the $500 billion global energy storage market projected for 2030.
