Abstract

Abstract In this study, the yield of nanosheets fabricated through the exfoliation of Li(Ni0.33Co0.33Mn0.34)O2 in aqueous solution was enhanced by performing an additional chemical oxidation step. The lateral dimensions and thickness of the obtained nanosheets were estimated via atomic force microscopy, and their chemical composition was determined using thermogravimetry, chemical composition analysis, and X-ray absorption near edge structure measurements, while their local crystal structure was examined using Raman spectroscopy and X-ray absorption fine structure techniques. In addition, the electrode properties of the restacked nanosheets in aqueous KOH solution were compared with those of the layer-structured bulk material.
