Enhanced Lattice Polarization and Directed Charge Transport Toward Pt Surface Sites Accelerate the Volmer Step in Piezocatalytic H2 Evolution on Co‐Doped BiFeO3

Advanced Energy Materials, EarlyView.
We report a Pt‐decorated Co‐doped BiFeO3 (Pt/BCFO) piezocatalyst achieving an H2 evolution rate of 1896.4 µmol g−1 h−1. Co‐doping induces lattice distortion, enhancing piezoelectric polarization, while Pt sites promote water dissociation. Embedded in a poly(vinylidene fluoride) matrix, Pt/BCFO enables efficient mechanical energy harvesting and catalyst

High‐Performance Noble‐Metal‐Free Perovskite Solar Cells Enabled by MoOX/Cr/Al Multilayer Electrodes

Advanced Energy Materials, EarlyView.
Cost‐effective perovskite solar cells (PSCs) are developed using a noble‐metal‐free MoOX/Cr/Al multilayer electrode. The devices achieve a power conversion efficiency (PCE) of 25.6%, competitive with that of Au‐based devices (26.3%), and a 25.5 cm2 mini‐module shows 21.3% PCE.

Debunking Common Myths & Misconceptions About NMC Positive Electrode Materials for Li‐ion Batteries

Advanced Energy Materials, EarlyView.
LiNixMnyCozO2 (NMC) and LiNixCoyAlzO2 (NCA) remain the choice for high‐energy‐density lithium‐ion battery positive electrode materials, yet many myths persist surrounding them. Herein, four common misconceptions are tackled to better inform the lithium‐ion battery field.

Redox Complexity in Sodium Manganese Hexacyanomanganate and Its Influence on Sodium‐Ion Storage Performance

Advanced Energy Materials, EarlyView.
The role of each Mn site in the Na3‐xMn[Mn(CN)6]·zH2O compounds’ redox activity was investigated using a combined experimental–computational approach, which shows that only the low‐spin Mn‐C site undergoes redox changes (Mn1+ to Mn4+), while high‐spin Mn‐N remains unchanged. The study confirms the presence of the Mn1+ intermediate and newly reveals its

Redox‐Mediated Aluminum–Air Fuel Cells With Suppressed Hydrogen Evolution for Durable Power Generation

Advanced Energy Materials, EarlyView.
The redox‐mediated aluminum–air fuel cell (RM‐AAFC) integrates a soluble redox mediator, 7,8‐dihydroxy‐2‐phenazine sulfonic acid (DHPS), to facilitate the oxidation of aluminum and inhibit hydrogen evolution reaction (HER) through competitive reactions between DHPS reduction and HER on the Al surface.
