POROUS MANGANESE OXIDE-BASED LITHIUM ABSORBENT HAVING A SPINEL TYPE STRUCTURE, AND METHOD OF FABRICATING SAME

摘要

The present invention relates to a method of fabricating a porous manganese oxide-based lithium absorbent. The method of fabricating the porous manganese oxide-based lithium absorbent includes: a step of mixing a reaction material for synthesizing lithium-manganese precursors with an inorganic binder to prepare a mixture; a step of molding the mixture; a step of thermally treating the molded mixture to fabricate a porous lithium-manganese precursor molded product; and a step of acidifying the porous lithium-manganese precursor molded product to change lithium ions into hydrogen ions. Here, in the thermal treatment process, a gas may be generated to form pores in the porous lithium-manganese precursor molded product. The porous manganese oxide-based lithium absorbent according to the present invention may be easily handled and provide more absorption reaction sites than an existing molded absorbent to improve lithium absorption efficiency.
