Highly Stabilized Ni‐Rich Cathodes Enabled by Artificially Reversing Naturally‐Formed Interface

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The application of Ni‐rich cathode materials is obstructed by interfacial and structural instability. This work proposes a facile and cost‐effective Al‐based vapor‐phase surface reaction strategy on Ni‐rich cathode to maintain its structural integrity from near‐surface to bulk.

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Thulium-doped fiber laser with longitudinally segmented active fiber

Eighth International Workshop on Specialty Optical Fibers and Their Applications (WSOF 2025)
Nowadays, one of the main challenges of thulium-doped fiber lasers is thermal management. One prospective method to significantly reduce thermal load density along the fiber is using a segmented active fiber or active fiber with a longitudinal gradient of thulium-doping concentration.
