Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Mg Substitution Improves the Surface Stability of High‐Voltage Spinel Cathodes under Accelerated Aging Conditions

open access: yesAdvanced Functional Materials, EarlyView.
LiNi0.5Mn1.5O4 lithium‐ion battery cathodes exhibit poor cycling stability due to surface reconstruction and electrolyte degradation at high voltage. This work demonstrates that partial Ni substitution with Mg prevents surface reconstruction and creates a corrosion‐resistant surface layer during the early stages of cycling, hence reducing electrolyte ...
