Abstract

In article number 2000283 Sang Kyu Kwak, Jaehoon Kim and co-workers show that the interlayer spacing of hard carbon decreases after the initial intercalation of a few Li+ ions at the edge of the graphene layer, whereas the interlayer spacing is expanded during the initial intercalation of a few Na+ and K+ ions into the graphene layer. The dilated interlayer spacing is beneficial for Na+ and K+-ion intercalation at relatively higher potentials than is the case with Li+-ion intercalation.
