Macro‐ and Nano‐Porous 3D‐Hierarchical Carbon Lattices for Extraordinarily High Capacitance Supercapacitors (Adv. Funct. Mater. 24/2022)

Supercapacitors In article number 2201544, Yuto Katsuyama, Richard B. Kaner, and co-workers show that 3D-printed thick supercapacitor electrodes having bimodal porosity (≈20 μm macropores and 2–3 nm nanopores) can significantly enhance the overall cell energy/power densities by eliminating the use of inactive components such as current collectors and separators.
