Abstract

Provided are a lithium adsorbent prepared using an aerosol deposition method, including (a) synthesizing lithium manganese oxide powder, and (b) coating the lithium manganese oxide powder on a surface of a substrate by the aerosol deposition method, and a method of preparing the same. The lithium adsorbent is characterized in that the lithium manganese oxide powder may be directly coated on various substrates using the aerosol deposition method, thereby greatly reducing a decrease of a lithium recovery rate even after a long time has lapsed.Further, the lithium adsorbent having a large surface area prepared by the preparation method of the present invention is characterized by being easily handled, being selectively reacted with lithium ions, having a larger adsorption area, being physically and chemically stable, and being used reversibly.
