Typically, in LIBs, anodes are graphite-based materials because of the low cost and wide availability of carbon. Moreover, graphite is common in commercial LIBs because of its stability to accommodate the lithium insertion. The low thermal expansion of LIBs contributes to their stability to maintain their discharge/charge. .
The name of current commercial LIBs originated from the lithium-ion donator in the cathode, which is the major determinant of battery performance. Generally, cathodes consist of a complex lithiated compound. .
