Abstract

? 2022 Elsevier B.V.Submicron-sized single crystal Li1.2Mn0.54Ni0.13Co0.13O2 was prepared to enhance the structural stability and lithium ion migration rate of Li-rich cathode materials. The preparation process of single crystal particles was beneficial for materials with good layered structures and low cation mixing degrees. Due to the single crystal morphology of the materials, the particles remained intact without cracks after cycling, which reduced side reactions between the cathode material and electrolyte, thus preventing the structural phase transformation. The preparation of submicron-sized single crystal particles provides a new strategy to improve the electrochemical properties of Li-rich cathode materials.
