Currently he is a PhD student at Adama Science and Technology University under the supervision of Dr Fekadu Gashaw, Dr Mesfin Abayneh and Dr Megersa Wodajo. He received his BSc degree in Applied Physics from Hawassa University in 2015 and his MSc degree in Solid State Physics from Dilla University, in 2017. Finally, this review will summarize recent research focus and recommend future research directions for nickel-rich NCM cathodes.įikadu Takele was born in Welega, Ethiopia, in 1993. Moreover, with an extensive collection of detailed mechanisms on atomic, molecular and micrometer scales, this review work can complement the previous failure, degradation and thermal instability studies of Ni-rich NMC. Hence, this review will recapitulate the current progress in this research direction by including widely recognized research outputs and recent findings. In particular, the thermal instability of Ni-rich NCM cathode active materials is the main issue of LIBs safety hazards. This is a huge challenge to commercializing these materials widely for use in LIBs. However, the surface degradation, mechanical failure and thermal instability of these materials are the major causes of cell performance decay and rapid capacity fading. Among the existing commercial cathodes, Ni-rich NCM are the most promising candidates for next-generation LIBs because of their high energy density, relatively good rate capability, and reasonable cycling performance.
