Electronic properties of lithium-ion conductive amorphous lithium phosphorus oxynitride.

The valence band maxima of Li + conductive amorphous lithium phosphorus oxynitride (LiPON) electrolyte depend on the chemical bonding states, and isolated nonbonding oxygen raises them. In contrast, the conduction band minima of the LiPON are independent of the composition and the values are less than the work function of Li.
