➀ Researchers at the University of Liverpool have developed a novel energy storage material using sustainable carbon nanomaterial, Gii, which could lead to smaller, more efficient energy storage capabilities in IoT devices; ➁ The material combines Gii with iron oxyhydroxide (FeOOH) to create a powerful new electrode material for micro-supercapacitors; ➂ The electrode is water-based, offering a sustainable alternative to solvent-based electrodes commonly used in IoT devices.
