The Solid State Graphene Supercapacitor Battery, proudly made in South Africa, is an advanced UL 8570–certified energy storage solution designed for high-performance, long-life, and ultra-safe applications. Graphene was first isolated in 2004. Over the past 20 years, graphene has found hundreds of innovative applications, from sensors and. Energy storage, especially battery storage, is becoming the backbone of Africa's modern power systems. And increasingly, it's not a luxury add-on. The global graphene battery. With 200x the strength of steel and 98% optical transparency, graphene's been called a "wonder material. " But its real magic happens in energy storage: "Graphene enables charging speeds that feel like science fiction—researchers at MIT demonstrated 30-second phone charges back in 2021.
