The next-generation rechargeable batteries are highly desirable; however, low-power density, low-stability, and high cost are major challenges due to multiple-electron transfer reactions. For the promotion of electrochemical reactions during charge/discharge processes, development/design of new catalysts is highly required [ 8, 9 ].
structures for various rechargeable batteries. To further enhance electrocatalytic processes, including the adsorption/desorption and activation behaviours of reactants and products in battery systems, dual versions of single-atom catalysts within SACs should also be considered for their possible synergistic e ects.
For the past few years, a growing number of studies have introduced catalysts or the concept of catalysis into battery systems for achieving better electrochemical performance or designing materials with distinctive structures and excellent properties.
In terms of catalysis used in secondary batteries, the first things we could think of are Li-S and Li-O 2 batteries. As for the LSB, (19−22) it is consisted of a cathode with sulfur (S) as the active material, electrolyte (solid-state or liquid), an anode (Li metal), and a separator (Figure 2 a).
In this part, we expect that the catalysts can speed up the reaction kinetics as much as possible, leading to a better electrochemical performance of batteries. Second, the formation of electrode–electrolyte interfaces in batteries is narrated in detail. This section shows the importance of selective catalysis for battery systems.
Although carbon and catalysts materials are efficient for high performance Li-S batteries, integrating too many carbon and catalysts into the composite S cathode for providing high electronic conductivity and enough catalytic activities will cause a decrease in the mass and volume energy densities .
