| Abstract Scope |
Lithium-ionbatteries(LIBs) have a wide range of applications due to their excellent properties, resulting in a sharp increase in the quantity of waste LIBs. The cathode materials of waste LIBs contain a large amount of metal ions such as cobalt, manganese, and nickel. If not properly treated in a timely manner, it can lead to resource waste and environmental pollution. The molten salt method provides a possibility for the recovery of valuable metal materials from the cathode of LIBs. In this paper, the feasibility of recovering metallic manganese through the molten salt method is analyzed through thermodynamic calculations. The results show that at temperatures above 600°C, Mn(IV) can spontaneously reduce to Mn(III), and Mn(III) gradually undergoes reduction when a voltage is applied, following the reduction process of Mn(IV)→ Mn(III)→ Mn(II)→ Mn. This paper provides theoretical support for the molten salt deoxidation recovery of metallic manganese from lithium manganese oxide. |
