In article number 2301118, Guang Feng and co-workers develop a multiscale modeling method to investigate the effect of pore topology and electrode metallicity on supercapacitor performance using porous graphdiynes. The reported simulations quantitively unveil the effect of image charges on energy storage in nanopores. Based on this understanding, they predict that doped porous graphdiynes can deliver both outstanding energy and power densities.
