Sodium ion batteries (SIBs) are a potential alternative to diversify the energy landscape, beyond Lithium-ion batteries (LIBs), due to their similar storage mechanism and easy technology transfer. Currently, the benchmark anodes for SIBs are hard carbons (HCs), since sodium ions do not intercalate into graphite. HCs can be produced from a variety of waste precursors and therefore are more sustainable and less geopolitically compromised than natural graphite, mainly concentrated in China. The electrochemical degradation of SIBs can be attributed to the greater reactivity of HC anodes compared to graphite. A deeper operando understanding of the degradation mechanisms in SIBs, coupled with engineering of the materials and electrolyte to ensure that a better and more protective solid electrolyte interface (SEI) is formed, is needed for an accelerated scale up of this technology. In this talk I will show you some of the strategies we have developed for these aims.
