Flint, a Singapore-based startup supported by Shell and OPPO Research Institute, has developed a bio-based paper battery made from cellulose fibers found in plant cell walls. This innovative battery is cost-effective, durable, sustainable, fire-resistant, rechargeable, and offers a lifespan comparable to traditional batteries. It is 1.8 times cheaper per kWh compared to lithium-ion batteries and can naturally biodegrade. WH-Power has also introduced a new energy storage technology with a quasi solid-state electrolyte for stable operation with Li anodes and cathodes, high ion conductivity, and fast-charging capability. These advancements in plant-based and solid-state battery technologies aim to improve the sustainability profile of electric vehicles and other applications, offering promising solutions for the future of energy storage.
