We discuss metallic 1T-MoS₂ as an anode material for sodium-ion batteries (SIBs). In situ Raman is used to investigate the stability of metallic MoS₂ during the charging and discharging processes. Parallel first-principles computations are used to gain insight into the experimental observations, including the measured conductivities and the high capacity of the anode.
