Reconstruction of Ultrafine MnS‐Induced Vacancy‐Rich Co9S6.29 Precatalysts in Mesoporous S‐Doped N‐Rich Hollow Carbon Nanotubes Enables Dynamic O‐Vacancy Cycling for High‐Performance Zn‐Air Batteries

Advanced Science, EarlyView.
We develop vacancy‐rich Co9S6.29 precatalysts formed via ultrafine MnS‐induced lattice distortion in mesoporous S‐doped N‐rich hollow carbon nanotubes (CM@SNHCTs). This CM@SNHCT precatalyst is reconstructed into catalytically‐active cathode phases that enable efficient oxygen reduction/evolution reactions (ORR/OER) through dynamic O‐vacancy formation ...

3D‐Mixer‐Assisted High‐Entropy Doping of LiNiO2 for Co‐Free Ni‐Rich Cathodes in Lithium‐Ion Batteries

Advanced Science, EarlyView.
High‐entropy doping of Co‐free Ni‐rich LiNiO2 cathodes is achieved through a scalable 3D mixing process. Multi‐element incorporation stabilizes the layered structure, alleviates Li/Ni disorder and electrode swelling, and enhances cycling stability. This approach underscores the potential of high‐entropy strategies to deliver structurally robust and ...

Lithium Nitrate Regulated Sulfone Electrolytes for Lithium Metal Batteries

Angewandte Chemie - International Edition, 2020
AbstractThe electrolytes in lithium metal batteries have to be compatible with both lithium metal anodes and high voltage cathodes, and can be regulated by manipulating the solvation structure. Herein, to enhance the electrolyte stability, lithium nitrate (LiNO3) and 1,1,2,2‐tetrafuoroethyl‐2′,2′,2′‐trifuoroethyl(HFE) are introduced into the high ...

Lithium Redistribution in Lithium-Metal Batteries

Journal of The Electrochemical Society, 2012
A model of a lithium-metal battery with a CoO2 positive electrode has been modeled in order to predict the movement of lithium in the negative electrode along the negative electrode/separator interface during cell cycling. A finite-element approach was used to incorporate an intercalation positive electrode using superposition, electrode tabbing ...
