Typically, a basic Li-ion cell (Figure 1) consists of a positive electrode (the cathode) and a negative electrode (the anode) in contact with an electrolyte containing Li-ions, which flow through a separator positioned between the two electrodes, collectively forming an integral part of the structure and function of the cell (Mosa and Aparicio, 2018).
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production.
