   Abstract : Batteries are expected to be masterpieces for future large-scale energy storage, but the emergence of ecological and financial concerns has forced us to think about complementary battery technologies to the today outstanding lithium-ion batteries (LIBs). Therefore, the sodium-ion battery (SIB) is a concept worth studying - especially for large-scale applications due to the abundance of sodium as an element, the overall low cost anticipated, and the similarities with LiBs, which should ease a technology change.
