In this talk I will present our research on developing susianable anode free Na and Li batteries. I will present fundamentals of Li/Na nucleatrion on various curent collectors along with SEI characterisation in different electrolytes and full cells at coin and pouch level. In particular several characterisation techniques such as in operando optical microscopy, solid state NMR, ToF-SIMS, Hard ray XPS will be discussed. The impact of the chathode choice and SEI and full cell performance will also be discussed. In particular for Li we will discuss pairing anode Free Li with a Li2S8/carbon composite and full cell performance.
If time allows will also doscuss our reseacher on K ion batteries snd the inetrcalation into graphite with new insights provided into thickness change, SEI, intercalation mechanism and stage compounds. Characterisation methods such as in operando XRD, Rama and surafec characterisation via ToF-SIMS will be presented along with DFT calculations to back up the Raman results on intercalation compounds with geaphite.
