Ni-rich cathodes exhibit appealing properties, such as high capacity density, low cost, and prominent energy density. However, the inferior ionic conductivity and bulk structural degradation become bottlenecks for Ni-rich cathodes and severely limit their commercial utilization. Traditional coating and doping methods suffer fatal drawbacks in functioning as a unit and cannot radically promote material performance to meet the needs of Li-ion batteries (LIBs). Herein, we successfully devised an ingenious and facile synthetic method to establish Ni-rich oxides with a La₂Zr₂O₇ coating and Zr doping. The coating layer improves the ion diffusion kinetics and enhances Li-ion transportation while Zr doping effectively suppresses the phase transition of LiNi_0.8Co_0.1Mn_0.1O₂ cathode. Owing to the synergetic effect of Zr doping and La₂Zr₂O₇ coating, the modified material shows prominent initial discharge capacity of 184.7 mAh g⁻¹ at 5 °C and maintains 177.5 mAh g⁻¹ after 100 cycles at 1 °C. Overall, the proposed feasible electrode design method can have a far-reaching impact on further fabrication of advanced cathodes for high-performance LIBs.

富镍阴极具有吸引人的特性，例如高容量密度，低成本和突出的能量密度。然而，劣质的离子导电性和整体结构退化成为富镍阴极的瓶颈，并严重限制了它们的商业应用。传统的涂层和掺杂方法在作为一个单元使用时会遭受致命的缺点，并且不能从根本上提高材料性能以满足锂离子电池（LIB）的需求。在这里，我们成功地设计了一种巧妙而又简便的合成方法来建立具有La ₂ Zr ₂ O ₇涂层和Zr掺杂的富Ni氧化物。涂层改善了离子扩散动力学并增强了锂离子的传输，而Zr掺杂可有效抑制LiNi的相变_0.8 Co _0.1 Mn _0.1 O ₂阴极。由于Zr掺杂和La ₂ Zr ₂ O ₇涂层的协同作用，改性材料在5°C下显示出显着的初始放电容量184.7 mAh g ^-1，在1°C下经过100次循环后仍保持177.5 mAh g ^-1。总体而言，所提出的可行的电极设计方法可能对高性能LIB的高级阴极的进一步制造产生深远的影响。
