New paper batteries biodegrade in six weeks, offers safer energy storage
Flint, a Singapore-based company specializing in the development of sustainable energy solutions, is making waves in the world of battery technology with its cutting-edge paper batteries. These batteries promise to deliver impressive advantages over traditional energy storage options, thanks to their flexibility, lightweight design, safety, and eco-friendly features.
Flint’s paper batteries are a type of quasi-solid battery, utilizing an innovative hydrogel ring that acts as both a separator and an electrolyte within a piece of paper. This setup differentiates it from conventional lithium-ion batteries by replacing toxic and geopolitically sensitive materials like lithium, cobalt, and nickel, with safe and sustainable alternatives such as zinc and manganese. The hydrogel-based design also contributes to the battery’s ability to biodegrade completely within six weeks when buried in soil, leaving no harmful residues behind.
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.
