Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

Advanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Design of discrete PI‐PR2 controllers for time‐delayed systems using dominant pole placement method

Asian Journal of Control, EarlyView.
Abstract This paper presents a new controller structure known as the proportional‐integral proportional‐double‐retarded (PI‐PR2) designed for discrete‐time systems with time delay. The dominant pole placement technique, which is frequently encountered in control systems, is used as the primary design method. The design method starts that dominant poles

Comparative Study of High Voltage Spinel∥Lithium Titanate Lithium‐ion Batteries in Ethylene Carbonate Free Electrolytes

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
FEC and sulfone‐based co‐solvents are investigated as EC‐free electrolytes for LNMO∥LTO cells. FEC‐containing electrolytes demonstrate enhanced electrochemical stability by stabilizing the CEI and SEI layers, mitigating transition metal migration. Conversely, sulfone electrolytes form thinner CEIs and thick, sulfur‐rich SEIs, which are less effective ...

Graphite Co‐Intercalation Chemistry in Sodium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Traditional intercalation chemistry in lithium‐ion batteries cannot allow sodium storage in graphite. The co‐intercalation chemistry changes the situation. It enables reversible and ultrafast sodium storage in graphite. Revisiting challenges and summarizing recent advances are of significant importance to exploit the full potential of graphite in ...

Comparative Investigation of Three Mg Doping Strategies in NMC811 Cathodes for High‐Energy Density Lithium‐Ion Batteries

Batteries &Supercaps, EarlyView.
Magnesium (Mg) doping is explored as a stabilization strategy for high‐capacity LiNi0.8Mn0.1Co0.1O2 (NMC811) cathodes. Three doping routes are compared, revealing that solid‐state lithiation delivers the best cycling stability. Operando X‐ray diffraction and electrochemical dilatometry link reduced cation mixing and lattice stabilization to improved ...
