Ion intercalation reactions within layered or two-dimensional host materials have attracted considerable attention in the field of electrochemical energy storage. They involve the insertion of ions into the interlayer spaces of host materials causing small structural changes. This yields relatively high chemical and electrochemical reversibility and cycling stability, making layered materials promising candidates for applications in high-power energy storage devices. Currently, improving the kinetics of ion intercalation reactions is at the core of such research efforts. This includes a wide variety of approaches, including reducing crystallite sizes, carbon nanocomposite formation, expanding interlayer distances, electrode architecture design with hierarchical porosity, or facilitating ion-solvent cointercalation reactions. While any of these strategies can enhance the overall kinetics, they typically aim to overcome different limitations of the charge storage process.
