Unlocking Physical Properties of Charge Density and Electron Localization Function of Metal/Metalloid Substitution in Hybrid Semiconductors of Silicon–Germanium Oxide: A DFT Simulation

A hybrid alloy of [Li-ion/boron(B), aluminum(Al), gallium (Ga)] battery is figured out by a simulated anode of germanium-silicon oxide (GeOSiO) and tin-silicon oxide (SnOSiO) nanoclusters. (GeOSiO) and (SnOSiO) nanoclusters have been designed and charchterized as the electrodes for hybrid Li-ion batteries (LIBs) due to forming [LiB(GeOSiO)], [LiAl(GeOSiO)], [LiGa(GeOSiO)], [LiB(SnOSiO)], [LiAl(SnOSiO)], and [LiGa(SnOSiO)] nanoclusters. In this work, the metallliod/metal of third group elements have been studied in hybrid LiB-, LiAl-, LiGa-ion batteries through using computational approaches due to density state analysis of charge density differences (CDD), total density of state (TDOS), electron localization function (ELF). Higher Ge/Sn to Si content can increase battery capacity for energy storage compared to net Li-ion batteries and might improve the rate performances by enhancing electrical conductivity. Besides, (GeOSiO) and (SnOSiO) anode materials may advance cycling consistency by excluding electrode decline and augments the capacity owing to higher surface capacitive impacts.
