Diluent Conformational Flexibility Enhances Interfacial Kinetics in Safe High-Voltage Potassium Batteries.
Introducing diluents into high-concentration electrolytes to promote anion decomposition is a conventional strategy for stabilizing electrode interfaces, but this approach overlooks how the conformational dynamics of the diluent itself regulate cation solvation. Here, three electrolytes based on a potassium salt, tribu...
