Favorable Desolvation and Uniform Zn Deposition of Silica Modified Zn Anode for High Performance Aqueous Zn‐Ion Batteries

Advanced Science, EarlyView.
The uniform Zn deposition and fast desolvation of Zn anode are realized by using a hydrophilic fumed nano‐silica coating with zinc alginate (Alg) as a functional binder. The interaction between the H2O in the solvation structure and ‐OH functional group of SiO2 facilitates the desolvation process. In addition to the Zn2+ guiding effect of Alg, the fast

Measurement of Noise in Supercapacitors

Metrology and Measurement Systems, 2017
AbstractA developed method and measurement setup for measurement of noise generated in a supercapacitor is presented. The requirements for noise data recording are considered and correlated with working modes of supercapacitors. An example of results of low-frequency noise measurements in commercially available supercapacitors are presented.

In Situ Converting Conformal Sacrificial Layer Into Robust Interphase Stabilizes Fluorinated Polyanionic Cathodes for Aqueous Sodium‐Ion Storage

Advanced Science, EarlyView.
A unique interfacial conversion concept is proposed to establish robust cathode electrolyte interphase for stabilizing fluorinated polyanionic cathodes in aqueous electrolytes. In a typical case, the conformal Al2O3 sacrificial layer is predeposited on high‐voltage sodium vanadium oxy‐fluorophosphates cathode, which can progressively react with trace ...
