Abstract

The powerful and rapid growth of Lithium-ion batteries in the field of secondary batteries has resulted in a shortage of lithium resources, which has led to an increase in the price of batteries. As a result of these factors, sodium-ion batteries, also known as NIBs, have developed into one of the most appropriate options for large-scale energy storage devices. These batteries have a low cost, limitless sodium reserves and a working principle that is similar to that of LIBs. Na-ion batteries, also known as NIBs, have gained a lot of attention as a potential excellent candidate for grid-scale energy storage systems due to the abundance and accessibility of Na as well as its electrochemistry that is very similar to that of the well-established LIBs technology. This review article provides a concise assessment of the most recent developments in the field of electrode materials for NIBs, including the discovery of new electrode materials and the Na storage mechanisms possessed by those materials.
