Self-Reconstructing, Conductive Bismuth Organic Framework Enables Effective Alloying and High-Capacity Potassium-Ion Anodes.

Conversion-type anodes can deliver high capacities for potassium-ion batteries (PIBs), but practical deployment is hindered by severe alloying-induced volume expansion that destabilizes electrode interphases. Meanwhile, many porous host materials are electronically insulating and require substantial carbon additives, w...

Emerging Aluminum‐Ion Capacitors and Lessons from Battery Chemistry

ABSTRACT Aluminum‐ion capacitors (AICs) attract significant research interest as multivalent energy‐storage devices that aim to increase energy density beyond that of conventional monovalent‐ion supercapacitors. Owing to the trivalent charge of Al3+ and the abundance, low cost, and relative chemical stability of alumin...
