“…These oxalate precursors are convertible to spherical-shape NCM811 oxide microparticles, through a preliminary design of low heating rates (e.g., 0.1 and 0.8 °C/min) for calcination and lithiation. The outcome oxide cathode particles also demonstrate improved tap density (e.g., 2.4 g mL(–1) for NCM811) and good specific capacity (202 mAh g(–1) at 0.1 C) in coin cells and reasonably good cycling performance with LiF coating.…”
