Electrical Effects of Ionic Deficient Cubic Ferrite Spinels: A Case Study on MgFe2O4

Advanced Physics Research
Electron transport via indirect exchange interactions between octahedral sites in spinels is affected by cationic or anionic vacancies. Thus, the deviation of the electron hopping mechanism is investigated, from a constant energy barrier toward a ...

Optimización de espinelas LiCo_yMn_2-yO₄ para electrodos positivos de baterías recargables de ion-litio mediante ajuste del dopado y de la temperatura de síntesis

Boletín de la Sociedad Española de Cerámica y Vidrio, 2004
The synthesis of LiCoyMn2‑yO4 (0 < y ≤ 0.33) spinels with optimised electrochemical performances in the 4V region has been carried out. They have been obtained by an original procedure designed by us, based on the reaction at 750ºC between the ...

CuO‐CuAl2O4 Catalyst for Synthesis of 1‐Methylindole by Alcohol Amine Method

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cu‐based catalysts used for the vapor‐phase synthesis of 1‐methylindole from N‐methylaniline and ethylene glycol are prone to Cu sintering and deactivation under the reaction conditions. In this work, CuO‐CuAl2O4 catalysts were prepared by a coprecipitation method and applied to the synthesis of 1‐methylindole via alcohol amine route.

Overview of Research Progress and Development of Cathode Materials for Aqueous Na‐Ion Batteries

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aqueous sodium‐ion batteries (ASIBs) have now been viewed as the promising energy storage technique for the grid application due to their intrinsic safety and cost‐effectiveness. However, their energy density and cycling stability are still unsatisfactory accompanied by the narrow electrochemical stability window of water and parasitic side ...

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

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 ...

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

Carbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...
