From: Reversible and selective ion intercalation through the top surface of few-layer MoS2
Li intercalation of MoS2 through the top surface and edges. a–b In situ optical microscopy images of Li intercalation into MoS2 through top surface and edges, respectively. Scale bars, 5 µm. c-d In situ Raman spectra of Li intercalation into MoS2 with sealed edge and open edge, respectively. e Three cycles of in situ Raman spectra of Li intercalation MoS2 with sealed edge. The voltages were with respect to Li/Li+
