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.

NiFe‐NO3 Layered Double Hydroxide as a Novel Anode for Sodium Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This study demonstrates, for the first time, the effectiveness of using LDH as an anodic material in SIB. The material is stable and show high specific capacity, the reaction mechanism has been thoroughly investigated and comprehensively described and involves a phase change reaction followed by sodium intercalation.

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 ...
