With respect to the calculations, we are mainly interested in the changes of the electronic properties induced by adsorption of BMP-TFSI and its coadsorption with Li, both of surface properties and of characteristic properties of BMP-TFSI. Figure As expected, adsorption of Li (Figure ) leads to a charge transfer from the alkali metal atom to the topmost graphite layer, which results in a decrease of the work function and a rigid band shift of the valence band with respect to the Fermi energy (Ef), specifically of the topmost graphite layer.
