"surface-area limitations restrict supercapacitors, overcome using UV-laser resin printing constructing honeycomb-like scaffold riddled with billions of microscopic cavities infused with high-capacity vanadium oxide... vastly expands internal surface area... excellent long-term durability, maintaining 82% charge capacity after 1,500 continuous cycles... open-source 3D-printed test cell helps other labs gather more reliable data... safer, cheaper, more sustainable (lithium-free) large-scale grid energy storage"
