Herein, a novel hierarchical precursor of Ni_0.8Co_0.1Mn_0.1O_x@Ni_0.8Co_0.1Mn_0.1(OH)₂ is proposed for the first time, which was synthesized by densely integrating co-precipitated Ni_0.8Co_0.1Mn_0.1(OH)₂ nanoflakes onto spray-pyrolyzed Ni_0.8Co_0.1Mn_0.1O_x microspheres. The co-precipitated hydroxide layer can prevent the Ni_0.8Co_0.1Mn_0.1O_x microspheres from fragmenting during the sintering process, thus yielding uniform LiNi_0.8Co_0.1Mn_0.1O₂ spheres with a hollow interior morphology. Strikingly, the obtained spherical LiNi_0.8Co_0.1Mn_0.1O₂ cathode exhibits improved tap density and initial coulombic efficiency, as well as excellent cycling stability and superior rate capability. Discharge capacities of 169 mA h g⁻¹ after 300 cycles at 1C (180 mA g⁻¹) of between 2.8 and 4.3 V are consistently obtained, corresponding to 90.5% capacity retention. Significantly, it is strongly envisioned that this novel hierarchical structure design concept holds great promise for the architectural construction of other energy storage materials.

氧化物微球上致密集成的氢氧化物纳米薄片的新型分层前体，朝向锂离子电池的高性能层状富镍阴极†

在此，首次提出了一种新型的Ni _0.8 Co _0.1 Mn _0.1 O _x @Ni _0.8 Co _0.1 Mn _0.1（OH）_2的分层前体，它是通过将共沉淀的Ni _0.8 Co _0.1 Mn _0.1（OH）致密集成而合成的。）将_2个纳米薄片装到喷雾热解的Ni _0.8 Co _0.1 Mn _0.1 O _x微球上。共沉淀氢氧化物层可防止Ni _0.8 Co _0.1 Mn _0.1 O _x微球在烧结过程中会碎裂，从而产生具有内部内部形态的均匀的LiNi _0.8 Co _0.1 Mn _0.1 O ₂球。令人惊讶地，所获得的球形LiNi _0.8 Co _0.1 Mn _0.1 O ₂阴极表现出改善的振实密度和初始库伦效率，以及优异的循环稳定性和优异的倍率能力。在1C下进行300次循环后的放电容量为169 mA hg ^-1（180 mA g ^-1一致地获得2.8至4.3 V之间的）（相当于90.5％的容量保持率）。值得一提的是，人们强烈预见到这种新颖的分层结构设计概念对于其他储能材料的建筑结构具有广阔的前景。
