Sodium having similar chemical properties to lithium, both being alkali metals, makes it an ideal candidate for research as a new type of rechargeable Ion battery. The workings of a Sodium-Ion battery (NIB) is similar to that of the LIB, the difference being the materials used and that sodium ion tends to form a complex with the anode material unlike the lithium ions that tend intercalate between the anode material layers. Sodium and salts of Sodium are relatively cheap and abundant compared to that of lithium. For example, sodium containing precursors are widely available in the USA with a reserve of 23 billion tonnes of soda available. This would make sodium a more viable and cost effective alternative for grid energy storage. NIB’s also
