Abstract

Based on first-principles calculations, the potential of holey graphyne is investigated for battery applications in terms of the storage capacity, volume expansion, diffusion barrier, and metal polysulfides binding. We found substantially higher storage capacities of Li (873 mAh/g) and Na (558 mAh/g) than typical graphite anodes (372 mAh/g for Li and
