Abstract
A method of regenerating a metal oxide, includes: obtaining the metal oxide by applying a pretreatment process to a lithium ion battery; adding a metal oxide to an inorganic acid or an organic acid to create a dissolved solution; adding a reducing agent to the dissolved solution to generate a metal solution; adding a water-soluble compound to the metal solution; and heating the metal solution to initiate a solution combustion synthesis reaction to obtain a solid.
