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.
