Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

open access: yesAdvanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh‐Q Cavities and Waveguides

open access: yesAdvanced Materials, EarlyView.
Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Conjugation Pathway of Benzobisoxazoles in Polymer Donors Mediates the Charge Management and Enables Organic Solar Cells with Record Certified Efficiency

open access: yesAdvanced Materials, EarlyView.
Herein, the conjugation pathway isomerism of the benzobisoxazole (BBO) building block is systematically compared, by which a certified efficiency of 19.1% is obtained in corresponding all‐polymer solar cells. Abstract Charge management plays a pivotal role in achieving high‐performance bulk heterojunction (BHJ) organic solar cells (OSCs). In this study,
