Our work, focused on the LiCoO2 intercalation-type cathode, suggests that the most influential atomic level features for enhanced interface kinetics pertains to ET properties of the electrode material surface and IT properties of the electrolyte. Surface engineering yielding stronger coupling, 𝐻 DA , between electronic donor and acceptor states through, e.g., promotion of certain surface facets, doping, or coating outlines promising avenues for improvement. Of promise is, similarly, electrolyte design that tune the balance in the interaction of Li + with the electrolyte as well as the electrode surface providing a flat free energy landscape for Li + transfer with small 𝛽, and 𝜔 𝐿𝑖 + . This work corroborate contemporary strategies in fast charging and high power battery design, but dresses the materials guidelines in an atomistic outfit aiming to benefit the nanoscale tailoring of battery material interfaces with improved charge transfer kinetics.
