- Abstract
Dual‐ion batteries (DIBs) exhibit a distinct set of performance advantages and disadvantages due to their unique storage mechanism. However, the current cyclability/energy density tradeoffs of anion storage paired with the intrinsic required electrolyte loadings of conventional DIBs preclude their widespread adoption as an alternative to lithium‐ion batteries (LIBs). Despite this, their reduced desolvation penalty and low‐cost electrode materials may warrant their employment for low‐temperature and/or grid storage applications. To expand beyond these applications, this Perspective reviews the prospects of solid salt storage and halogen intercalation‐conversion as viable methods to increase DIB energy densities to a level on‐par with LIBs. Fundamental limitations of conventional DIBs are examined, technology spaces are proposed where they can make meaningful impact over LIBs, and potential strategies are outlined to improve cell‐level energy densities necessary for the widespread adoption of DIBs.
