It's Not Over until the Big Ion Dances: Potassium Gets Its Groove On Academic Article uri icon

abstract

  • 2018 Elsevier Inc. In a recently published paper in Chem, Zhu, Zhang, Yan, and colleagues unlock diffusion pathways for potassium ions within a double-layered V2O5 structure and demonstrate a potassium-ion battery with unprecedented performance characteristics including an average voltage of 3.2 V, an initial capacity of 131 mAhg1, and rapid charge/discharge capabilities even at high rates. The study serves as a remarkable illustration of the utility of mining metastable phase space to identify structural motifs that allow for mitigation of the diffusion challenges plaguing larger cations.
