Disclosed are systems and methods having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while simultaneously enabling environmentally and sustainably sound practices. A hybrid thermochemical cycle couples staged reforming with hydrogen production and residue chlorination. The residues of the upgrading are chlorinated, metals of interest are removed and bulk material is re-mineralized. Through the residue chlorination process, various metals including rare earths are concentrated and extracted. Energy is retained through chemical synthesis such as hydrocarbon and metal and non-metal chloride production. Produced chemicals are later exploited by redox reactions in the operation of an integrated gasification flow battery.

According to the present disclosure, a recovery efficiency of Li from a recovery object such as a used lithium ion secondary battery can be improved. The manufacture method disclosed herein includes a preparation step S11 of preparing a recovery object containing at least Li, and a chlorination heating step S12 of heating the recovery object together with a non-metal chlorine compound to produce LiCl. Since LiCl is soluble in water, Li can be easily recovered from the recovery object. That means, the technology disclosed herein makes it possible to separate Li from the recovery object immediately after the chlorination heating step S12, contributing to significant improvement of Li recovery efficiency.
