Electrochemically Induced Interphase by Complex Hydride Anions in Argyrodite Solid Electrolytes for Stable Lithium Metal All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
Complex hydride anion substitution in argyrodite electrolytes has attracted attention for improving interfacial stability, yet the influence of these anions at Li metal interfaces remains unclear. This work shows that electrochemically formed BH4−‐derived interphases enable stable high‐current full‐cell cycling.

CO2‐Assisted Hydrolysis of NaBH4: A Multi‐Function Platform for Enhanced Hydrogen Release, Regeneration of NaBH4, and CO2‐to‐CH4 Conversion

open access: yesAdvanced Science, EarlyView.
CO2 significantly accelerates hydrogen release from aqueous NaBH4 without metal catalysts, eliminating the need for downstream separation. Ball‐milling the hydrolytic products with Mg regenerates NaBH4 with yields exceeding 76% while simultaneously producing methane.

Ionic Elastomer Interface for Low‐Pressure and Durable All‐Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work reports an ionically conductive elastomer that enables stable all‐solid‐state batteries(ASSBs)under low external pressure. The soft elastomeric matrix, integrated with a LiG3‐based conductive phase(lithium bis(trifluoromethanesulfonyl)imide and triethylene glycol dimethyl ether), simultaneously delivers high ionic conductivity and mechanical ...
