In order to enhance the electrochemical energy storage properties of LiNi_0.8Co_0.15Al_0.05O₂ (NCA) cathode material, polyvinylpyrrolidone (PVP) was added in to modify the NCA morphology during the NCA preparation process and thus enhanced its electrochemical performance. A two-step co-precipitation method was used to prepare NCA precursors. With continuous stirring, solution A (0.2 mol·L^-1 CoSO₄) was slowly added into solution C (0.3 mol·L^-1 H₂C₂O₄ and PVP, the mass ratio of the PVP to all metal oxides was 1.64%(w/w)) to form a suspension. After that, solution B (0.32 mol·L^-1 NiSO₄, 0.053 mol·L^-1 CoSO₄ and 0.01 mol·L^-1 Al₂(SO₄)₃) was added into the suspension drop by drop, and then the solution was stirred for 2 hours and filtered. The obtained solid object was washed and dried in vacuum at 80℃ for 12 hours. The obtained sample was marked as MC₂O₄·2H₂O-PVA. The obtained sample mentioned above was mixed thoroughly with LiOH·H₂O at a molar ratio of 1:1.02. Then, the mixture was operated as the following steps:calcined at 500℃ for 5 h in air atmosphere, and then cooled to ambient temperature to grind for half an hour, after that sintered at 800℃ for 12 h in O₂ atmosphere. The obtained sample was named as NCA-PVP. The morphology and structure of the obtained samples were characterized by X-ray diffraction and scanning electron microscopy. The electrochemical performances were characterized by electrochemical workstation and cell tester with assembling into button battery. The results showed that the NCA material modified by PVP had a more complete rod-like structure, a better layered structure and a better electrochemical energy storage property due to the PVP space and electrostatic effects. The initial discharge specific capacity and charge-discharge efficiency of the sample at 0.1C has increased from 143.36 mAh·g^-1 and 78.25% to 170.24 mAh·g^-1 and 89.20%, respectively. The capacity retention rate was 94.28% after 50 cycles at 0.2C.
