Carbothermic method
Carbothermic reactions involve the reduction of substances, often metal oxides (), using carbon as the reducing agent. These chemical reactions are usually conducted at temperatures of several hundred degrees Celsius. Such processes are applied for production of the elemental forms of many elements. The ability of metals to participate in carbothermic reactions can be predicted from Ellingham diagrams. WebApr 15, 2024 · In that study, the carbon present in the batteries was found to trigger a carbothermic reduction of the metal oxides. However, when the temperature increases, the oxidative conditions promote the removal of graphite, and at 700 °C the carbothermic reduction is restrained.

WebThe carbothermic reduction of LNO (which has a layered structure) can produce Ni 3 O 4. Then, Ni 3 O 4 can be further reduced by C and CO into Ni and NiO. The use of carbon promotes the destruction of the oxygen framework of lithium metal oxides, where metals with high valence states have strong chemical bonds with oxygen ( Shi et al., 2024 ).
