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 ...

Zn/Al‐NO3 Layered Double Hydroxide as Alternative Activator for Nitrile Rubber Vulcanization: Effect of the Accelerator‐to‐Sulfur Ratio on Curing Kinetics and Network Properties

Journal of Applied Polymer Science, EarlyView.
Zn/Al‐NO3 layered double hydroxide offers a low‐zinc alternative for sulfur vulcanization of nitrile rubber, reducing nominal zinc loading by an estimated 71%. Its potential as a vulcanization activator depends on the curing system: conventional curing preserves tensile strength despite slower kinetics, whereas efficient curing maintains comparable ...
