Sodium co-intercalation in graphite negative electrodes delivers high-rate kinetics, and yet its implementation is plagued by notorious reaction potential. Here, the authors develop a flexible electrolyte design strategy based on synergistically competitive coordination that tailors the co-intercalation potential to 0.4 V in dilute ether systems, providing screening guidance for more potential regulation electrolytes.
