Can single atoms revolutionize battery technology? This perspective examines the use of single atom catalysts (SACs) in lithium metal batteries (LMBs) to overcome kinetic challenges associated with reaction and diffusion barriers. The focus is on tandem reactions, including desolvation, plating, and corresponding catalysis behaviors, analyzed from the interface to the electrode interior. Single atom catalysts are key to improving processes in batteries. The author introduces and analyzes tandem reactions—desolvation and reaction, plating, and related catalysis—from interface to electrode interior. The principal mechanisms of highly efficient SACs in overcoming specific energy barriers to reinforce catalytic electrochemistry are discussed. The study heralds a new strategy for UPD-directed synthesis of bimetallic NCs, opening avenues for advanced electrocatalyst design. The ideal atomic efficiency of SACs makes them promising candidates for resolving issues related to five types of barrier-restricted processes. This offers a new paradigm for steering the selectivity of electrocatalysts in chemical reactions. High-efficiency atomic-level catalysts have a significant impact on specific energy barriers. The potential impact of future developments of this research in high‐efficiency atomic‐level catalysts in batteries is presented.
