With the increase in energy demands, harnessing energy from renewable sources has become increasingly important for sustainable development. However, renewable energy sources are intermittent in nature as they depend on factors like weather, location, efficiency and available infrastructure. Thus, efficient energy storage systems, especially for large-scale are required to store, transfer and utilize the energy produced from renewable energy sources . Rechargeable metal-ion batteries are used extensively to store energy in the form of chemical energy which can be converted back to electrical energy whenever required. Among all the metal-ion battery, Li-ion batteries (LIBs) are leading the energy storage devices market, especially in portable devices such as smartphones and laptops . Li metal-ion batteries has even opened extraordinary possibilities in automotive sector and electric vehicles market recently. The long cycle life, high efficiencies and high energy densities are the main reason behind the success of LIBs. However, for large scale energy storage, LIBs have certain shortcomings such as its relatively low energy density, and safety issue owing its high reactivity in air. Very low abundance of Li sources is also a major concern which ultimately contributes to the high price of these batteries. These issues demand for cheap, efficient and sustainable alternatives of LIBs.
