A novel ionic liquid (IL) 1-ethyl-2,3-dimethylimidazolium tetrafluoroborate ([Emmim][BF4]) with trialkyl substitution imidazolium cation was synthesized, and its binary system blended with acetonitrile (ACN) under different concentrations were prepared and investigated as possible electrolytes for supercapacitors. The physico-chemical properties such as density, viscosity, and electrical conductivity...
Being eco-friendly, cost-effective, easy to synthesize and handle, starch-based electrolytes have tremendous advantages for electrochemical device fabrications. Starch electrolytes synthesized by crosslinking process result in stable, flexible, free-standing films which can be molded in different shapes and sizes. Rice starch–based material, prepared using glutaraldehyde as crosslinker and NaClO4...
1,1,2,2-Tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) was selected as a co-solvent of ionic liquid for fabricating the functional electrolyte of Li-S batteries. The basic properties of the electrolyte and electrochemical performances of the cell with alterative TTE contents were intensively investigated. It is found that the fluorinated ether helps to promote ion conduction in the electrolyte,...
A series of layered Li[Li0.2Mn0.54Ni0.13Co0.13]O2 cathode materials, of which manganese source was electrolytic manganese dioxide, with different contents of SO42− were successfully synthesized via ball-milling process and solid-state sintering method. The obtained materials were characterized by XRD, XPS, SEM-EDS, C-S, ICP, and HR-TEM. All the obtained materials presented well-ordered layered structure...
LiBF4 has attracted much attention due to its better thermal stability, lower sensitivity to environmental humidity, and lower charge transfer resistance provided by its solution, especially at high voltage. Herein, the effects of the concentration of LiBF4 salt on the stability and electrochemical properties of LiNi0.5Mn1.5O4 (LNMO) cathode material have been investigated by using the mixed solvents...
