Unravelling the enhanced high‐temperature performance of lithium‐rich oxide cathode with methyl diphenylphosphinite as electrolyte additive 10.1002/celc.201800061 2018-03-30 Lithium‐rich oxide cathode materials with high energy density attract much attention, however, tend to suffer from serious capacity fading during cycling, especially at elevated temperature. In this work, Methyl diphenylphosphinite (MDP) is studied as electro...
An all Solid State Zinc Air Battery with a Corrosion Resistant Air Electrode 10.1002/celc.201800269 2018-03-30 We illustrate an all solid state Zn‐air battery by utilizing the ability of titanium nitride functionalized molecular catalyst to mediate oxygen reduction reaction by arresting the parasitic corrosion chemistry and the hydroxide holding capacity of Zirfon mem...
Reversible Delithiation of Disordered Rock Salt LiVO2 10.1002/celc.201800189 2018-03-30 A rigid crystal lattice, where cations occupy specific positions in the lattice, is generally regarded a critical requirement to enable Li+ diffusion in the bulk of conventional cathode materials, while disorder is generally considered as detrimental. Herein,...
