NCM9271 (LiNi0.92Co0.07Mn0.01O2) cathode is an ultra-high nickel layered oxide material with single crystalline structure for lithium-ion batteries. Conventional NCM particles are polycrystalline—large agglomerates made of many tiny, nanosized "grains" held together. During charging and discharging, the volume change of these grains causes them to rub against each other, leading to microcracking along the internal grain boundaries.
