? 2022 Elsevier B.V.Li-rich layered cathode materials based on Li1.2Mn0.54Ni0.13Co0.13O2(LMNCO) have received increasing attention due to their high capacity densities. Nevertheless, these materials are still limited by their unsatisfactory cycle performances. In this work, the sol-gel method was used to construct heterostructured LiCo0.99Al0.01O2-Li1.2Mn0.54Ni0.13Co0.13O2 (LCAO-LMNCO) cathode material to overcome the capacity fading of LMNCO and charging voltage limitation of LiCo0.99Al0.01O2 (LCAO). The as-obtained heterostructured LCAO-LMNCO cathode material showed 273.90 mAh/g capacity at charge-discharge voltages of 2.0–4.6 V. The capacity retention was 72.10% after 100 cycles at 1 C, superior to LCAO or LMNCO.
