Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.
