For post-lithium batteries, carbon is still an opportunity as electrode materials, as hard carbons for anode purpose or as carbon fluorides as cathode one. Progresses in those fields will be rapid with the perfect mastery of electrochemical mechanisms and the use of characterization techniques coupled to galvanostatic cycling.
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the materials are used as both positive and negative electrodes.
