Fig. 4From: First Principles Study of Penta-siligraphene as High-Performance Anode Material for Li-Ion BatteriesThe calculated Li adsorption energies on P-Si2C4 surface (red cycles, left-hand axis) and the lattice constant change (blue squares, right-hand axis) as a function of the Li adsorption concentration (Li/(C+Si) ratio). The cohesive energy of bcc phase Li metal is also included for comparisonBack to article page
