MANUFACTURING METHOD OF LITHIUM ION ADSORPTION

摘要

The present invention relates to a manufacturing method of a lithium ion adsorbent. According to the present invention, the manufacturing method exhibits an excellent economic feasibility by synthesizing polythiophene having at least 90 percent in yields by using 2-thiophenemethanol as a precursor that is by synthesizing high-priced polythiophene from a relatively economical monomer. In addition, it is possible to provide an adsorbent which has an outstanding adsorption capacity for powdered carbon-based lithium ions, adsorbs lithium ions very efficiently, and has a large specific surface area, by activating at high temperature after treating the synthesized polythiophene with an alkali-activating agent.
