Abstract

The lithium-excess layered oxide LiLi_0.2Mn_0.54Ni _0.13Co_0.13O₂ has been surface modified with Al₂O₃ films grown with atomic layer deposition (ALD) and examined as cathodes for lithium-ion batteries. Al₂O₃ was grown on powders prior to electrode fabrication, directly on the electrode, and directly on the electrode followed by a heat-treatment at 300C in air. Compared to the bare electrode, an Al₂O₃ film on an as-formed electrode improved the cycle performance significantly. Furthermore, the heat treatment of the ALD-coated electrodes result in significant increase in capacity, due to the transformation of the as-deposited Al₂O ₃ to a better Li™-conductive material. X-ray photoelectron spectroscopy (XPS) results indicate that the heat-treatment leads to an inter-diffusion of atoms between the Al₂O₃ coating and the LiLi_0.20Mn_0.54Ni_0.13Co_0.13O ₂ core.
