Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes

Advanced Materials, EarlyView.
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

High Energy Density of Ball-Milled Fluorinated Carbon Nanofibers as Cathode in Primary Lithium Batteries

Nanomaterials
Sub-fluorinated carbon nanofibers (F-CNFs) can be described as a non-fluorinated core surrounded by a fluorocarbon lattice. The core ensures the electron flux in the cathode during the electrochemical discharge in the primary lithium battery, which ...

Gradient‐Modified Li‐Rich Manganese‐Based Oxides Cathodes with Breakthrough of Kinetic Limitation for High‐Performance All‐Solid‐State Lithium Metal Batteries

Advanced Materials, EarlyView.
The novel gradient‐modified LRMO has been synthesized via a one‐step mechano‐fusion process, with simultaneous S and Zr co‐doping in the near‐surface region and an amorphous coating. The synergistic co‐functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential, which enable ...

Superionic Amorphous Li2ZrCl6 and Li2HfCl6

Advanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the
