Solvent Co-Intercalation Reactions for Batteries and Beyond

Solvent co-intercalation is a process in which ions and solvents jointly intercalate into a layered electrode material during battery charging/discharging. It typically leads to rapid electrode degradation, but new findings show that it can be highly reversible, lasting several thousand cycles. Solvent co-intercalation has two important characteristics: (1) the charge transfer resistance is minimized as stripping of the solvation shell is eliminated and (2) the fact that solvents become part of the electrode reaction provides another means of designing electrode materials. The concept of solvent co-intercalation is chemically very diverse, as a single electrode material can host different types and numbers of…
