Abstract

A dataset in this report is regarding a research article "Crucial Role of Thioacetamide for ZrO₂ Coating on the Fragile Surface of Ni-rich Layered Cathode in Lithium Ion Batteries" [1]. Thioacetamide (TA) is introduced to form a homogeneous ZrO₂-coating in a facile method through washing with Zr(SO₄)₂ aqueous solution. The presence of the data in this paper indicated the role of TA for surface modification of LiNi_0.82Co_0.09Mn_0.09O₂ (NCM82) materials by ZrO₂, leading to improve the electrochemical performance of NCM82 Ni-rich cathode materials. These data were proceeded measurement electrochemical properties of cathode electrode on a battery cycler, the surface characteristics of the cathode materials were investigated by SEM, EDS mapping, TEM and XPS. X-ray diffraction (XRD, Rigaku, SmartLab) was used to evaluate the influence of the coating layer on the microstructure of active materials.

Keywords: Ni-rich layered cathode; Thioacetamide (TA) hioacetamide (TA); ZrO2 Coating; pH of the coating solution.
