- C60/SnO2 heterostructure interface potential barrier is analyzed in conditions of the lithium ions' first charging.
The controlled supply of electrons from SnO2 through the potential barrier could influence the Li+C60
and Li+SnO2 interaction. High electric field (>105 V cm−1) of the interface barrier could impact the overall
Li ions' diffusion/drift through the interface. Enhanced SnO2 grain boundary transport of Li ions, drawn in
through the C60/SnO2 interface potential barrier, could improve Li ions diffusivity in tin oxide and charging
efficiency of the cell.
