What is Overstoichiometric Li Storage in NCM622 about?
This article discusses the development of Ni-rich cathodes for lithium-ion batteries, focusing on the self-limiting phase transition that allows for reversible overstoichiometric lithium storage. By adjusting the discharge cutoff voltage, the researchers achieved a high capacity of 393 mAh g−1 and an energy density of 1070 Wh kg−1, while also revealing that the phase transition mitigates capacity decay through structural evolution. The findings provide insights into improving the cycling stability of high-c
