Unveiling the Formation and Evolution of the Cathode–Electrolyte Interphase in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
By integrating electrochemical impedance spectroscopy (EIS), background‐subtracted in situ Fourier‐transform infrared (FTIR) spectroscopy, and X‐ray absorption spectroscopy (XAS), this work reveals electrolyte decomposition and the reduced species involved in forming the cathode–electrolyte interphase (CEI) in lithium–sulfur batteries (LSBs), offering ...

Interconnected Hierarchically Porous Graphene‐Based Membrane Electrode for High‐Power and Long‐Cycle Lithium–Oxygen Battery

Advanced Science, EarlyView.
Lithium–oxygen batteries face an energy‐power trade‐off due to sluggish O2 transport and pore clogging by Li2O2. Simulations show that reducing tortuosity via interconnected macropores enhances oxygen mobility. A freestanding graphene electrode having interconnected macropores with low tortuosity delivers >2500 mAh g−1, stable lean‐electrolyte cycling,

Creating Cell‐Based Hybrid Noodles for Sustainable and Nutrient‐Balanced Diets via a Serum‐Free and Animal‐Free 3D Co‐Differentiation System

Advanced Science, EarlyView.
This study develops a 3D co‐culture and co‐differentiation system for porcine muscle stem cells (pMuSCs) and mesenchymal stem cells (pMSCs) on edible starch‐based scaffolds. The system simultaneously generates myotubes and adipocytes without using serum or chemical inducers.
