A team of researchers at Rice University in the US has fabricated 3D nanostructured thin-film electrodes using tantalum oxide nanotubes and “carbon-onion”-coated iron oxide nanoparticles. The thin films appear to be excellent lithium-ion batteries while being good supercapacitors too. The devices might be ideal in next-generation hybrid energy-storage applications, including wearable “smart textiles”……….
