ZrO2 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode has enhanced electrochemical performance and stability compared with thepristine. The discharge capacity of both samples have no significant difference. However, the 1.77 wt% ZrO2 coatedLiNi0.8Co0.1Mn0.1O2 material delivers enhanced charge-discharge cycling (capacity retention of 97.1 % after 100 cycles at 0.5C) while the capacity retention of pristine is 94.8 % under the same condition. Based on these, we can infer that the ZrO2coated LiNi0.8Co0.1Mn0.1O2 material shows great cyclability, originated from suppressing undesirable side reaction and decreaseeffectively electrolyte decomposition reaction. Therefore, the ZrO2 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode can beconsidered as an effective strategy for long-life Li-ion batteries.
