Abstract
Cu2O is an attractive material in terms of semiconducting properties and is considered a leading candidate in all-oxide photovoltaics. Electrochemical analysis of Cu2O, including Mott-Schottky (MS) and impedance spectroscopy (IS), provides a wealth of data on charge carriers, Fermi level and interface properties. MS and IS are usually measured in aqueous solutions. However, Cu2O is easily reduced or oxidized to Cu or CuO in aqueous solutions, the layer peels off after the analysis and there is a small voltage window for the tests. In some cases, an anti-corrosive n-type barrier layer is employed on top of the bare Cu2O electrode to make the measurement possible, which could result in...

Abstract
Formation of unstable solid electrolyte interphase (SEI) layers lacking of thermal stability in non-aqueous electrolytes of rechargeable batteries is the main bottleneck for their long-life cycling, especially at elevated temperatures. Inclusion of a small dose of functional electrolyte additives into the batteries' electrolyte can be highly beneficial to surmount this issue. Of these additives, vinylene carbonate (VC) has drawn particular attention thanks to its high ability to build protective layers at anodes showing good integrity and outstanding thermal stability. In addition to its primary roles in present-day lithium-ion batteries (LIBs), VC additive has also been examined in other...
