Sodium-ion batteries: towards a sustainable, low-cost energy storage ...
Figure 1. Schematic diagram of a Na-ion battery. It was these early studies into layered oxides that enabled Akira Yoshino to develop the first LIB (LiCoO 2 as cathode and graphite as anode), which was subsequently commercialized by Sony in 1991.Unfortunately, by contrast the non-intercalation of sodium ions in graphite became …
