Semiconducting silicon carbide (SiC) has been developed and characterized as an anode electrode for lithium (Li), sodium (Na), potassium (K), beryllium (Be), magnesium (Mg), boron (B), aluminum (Al), and gallium (Ga) ion batteries. This is due to the formation of Si(Li2)C, Si(Na2)C, Si(K2)C, Si(Be2)C, Si(Mg2)C, Si(B2)C, Si(Al2)C, and Si(Ga2)C nanoclusters. A comprehensive study on energy savings using Si(Li2)C, Si(Na2)C, Si(K2)C, Si(Be2)C, Si(Mg2)C, Si(B2)C, Si(Al2)C, and Si(Ga2)C complexes was conducted using computational approaches, including density of state analysis, charge density differences (CDD), total density of state (TDOS), and electron localization function analysis (ELF) for hybrid clusters of Si(Li2)C, Si(Na2)C, Si(K2)C, Si(Be2)C, Si(Mg2)C, Si(B2)C, Si(Al2)C, and Si(Ga2)C. Functionalizing lithium, sodium, beryllium, and magnesium elements can enhance the negative charge distribution of carbon elements as electron acceptors in Si(Li2)C, Si(Na2)C, Si(K2)C, Si(Be2)C, Si(Mg2)C, Si(B2)C, Si(Al2)C, and Si(Ga2)C nanoclusters. Increased Si/C content can boost battery capacity through Si(Li2)C, Si(Na2)C, Si(K2)C, Si(Be2)C, Si(Mg2)C, Si(B2)C, Si(Al2)C, and Si(Ga2)C nanoclusters for energy storage processes and improve rate performance by enhancing electrical conductivity. Additionally, the SiC anode material may improve cycling consistency by reducing electrode degradation and increasing capacity due to higher surface capacitive effects.
