Fig. 3From: First Principles Study of Penta-siligraphene as High-Performance Anode Material for Li-Ion BatteriesLi adsorption sites on a penta-siligraphene surface and the atomic configuration of the most stable structures of b Li2Si2C4 and c Li4Si2C4. The yellow (largest), gray (middle sized), and purple (smallest) spheres are Si, C, and Li atoms, respectively. H, T, B1, and B2 denote the Li adsorption sitesBack to article page
