“…23 Among these, synthesis strategies significantly influence the microstructure, particle size distribution, crystallinity, phase purity, and eventually the electrochemical performance of Li-rich cathode materials. 24 Solid-state reaction, 25 sol−gel method, 26 co-precipitation method, 27 microwave synthesis, 28 and hydrothermal synthesis 29 reaction methods. However, the final products often contain impurity phases and large irregular particles with a wider size distribution.…”
