摘要：
A method of making an ionically conductive layer for an electrochemical device is disclosed. A film is coated on electrode material particles or post-calendered electrodes. This coating may be a lithium borate-carbonate film deposited by atomic layer deposition. One example method includes the steps of: (a) exposing a substrate including an electrode material to a lithium-containing precursor followed by an oxygen- containing precursor; and (b) exposing the substrate to a boron-containing precursor followed by the oxygen-containing precursor.
