Diatomite‐Templated Synthesis of Single‐Atom Cobalt‐Doped MoS2/Carbon Composites to Boost Sodium Storage

cathode demonstrates unexpected stability with the cycle number exceeded 1200. The internal sodium storage mechanism is clarified with the aid of density functional theory calculations and in situ experimental characterizations. This work not only represents a substantial leap in terms of synthesizing SACs on 2D TMDCs but also provides a crucial step toward the practical sodium-ion battery applications.
