The interfaces of lithium cells were studied upon cycling within a scanning electron microscope (SEM). The LiMn2O4-cathode and the electrolyte consisted of a polymer matrix embedding a solution of LiPF6, while three types of anodes, Li, Cu and graphite, were tested and compared. For each configuration the morphology of the lithium deposit was correlated to the current density. Mossy lithium, at low current, and Li-dendrites, at high current, were observed at the Cu/electrolyte and Li/electrolyte interfaces, while no special morphology was noted at the graphite/electrolyte interface.
