In a recent study, Sang Kyu Kwak, Jaehoon Kim, and their team revealed fascinating findings about the intercalation behavior of lithium (Li+), sodium (Na+), and potassium (K+) ions in hard carbon. They discovered that the interlayer spacing of hard carbon decreases after the initial intercalation of a few Li+ ions at the edge of the graphene layer. In contrast, the interlayer spacing expands during the initial intercalation of a few Na+ and K+ ions into the graphene layer. This expanded interlayer spacing is beneficial for Na+ and K+ ion intercalation at relatively higher potentials compared to Li+ ion intercalation. These insights could have significant implications for the development of more efficient and higher-capacity batteries.-Scientific Journal cover design by scapiens
