The growing use of portable and wearable electronics has increased the need for flexible, safe, and sustainable energy-storage devices. This presentation highlights our work on advanced supercapacitor electrodes using biomass-derived nanocellulose, carbon nanomaterials, emerging two-dimensional materials, and transition-metal oxides deposited through DC/RF magnetron sputtering technology. It explores how precisely controlled sputtered coatings, binder-free electrode designs, surface engineering, and electrolyte selection influence electrochemical performance. Life-cycle assessment is also used to examine the energy, water, and material requirements of electrode production. Finally, the challenges of scalable fabrication and future perspectives of energy-storage devices will be discussed.
