Adsorbed CdO, TiO, RuO2, and IrO2 to silicon nanotube and carbon nanocage for anode of metal-ion battery: a computational study

摘要

Potential of carbon nanocage (C-52) and silicon nanotube (SiNT) as anodes in Li- and Na-ion batteries is examined. Effects of cadmium oxide, titanium oxide, ruthenium dioxide (RuO2), and iridium dioxide (IrO2) on abilities of C-52 and SiNT as anodes in Li- and Na-ion batteries are investigated. Results indicated that the metal oxides and metal dioxides can increase G(ad) of nanocages and nanotubes. Results demonstrated that Li-ion batteries have higher V-cell than Na-ion batteries. The metal oxides can improve the cell voltage of Li- and Na-ion batteries. The RuO2-SiNT and IrO2-C-52 as high-efficiency anodes in metal-ion batteries are proposed. Graphic abstract
