In this work, we report granular α-Fe2O3@FeS2 nanocrystals by a one-pot hydrothermal route. The as-obtained product as an electrode material shows excellent charge transfer ability and cyclic stability.
A silicon nanoplate-decorated graphite design is developed for lithium battery anodes via a simple ball milling process. The resultant silicon-graphite electrodes show high cyclic stability with high capacity, superior rate...
A versatile thin layer spectroelectrochemical cell employing specular reflection of the incident light beam from the electrode surface is described. Its application to in-situ uv–vis and FTIR characterization of the products of electrochemical reactions and to thin layer voltammetry and coulometry as well as conventional cyclic voltammetry is demonstrated for the oxidation of tetraphenylporphinatozinc in dichloroethane/tetrabutylammonium perchlorate solution. The advantages and disadvantages of this type of cell as compared to more conventional sandwich type optically transparent thin layer electrodes are discussed.
Supercapacitors, also known as electrochemical capacitors, have attracted more and more attentions in recent decades due to their advantages of higher power density and long cycle life. For the real...
