Abstract

LiNi_0.8Co_0.15Al_0.05O₂ batteries have been confirmed to be used in the new generation of electric vehicles. Hence, improving the capacity of LiNi_0.8Co_0.15Al_0.05O₂ batteries is of great significance to increase the endurance of electric vehicles. In this study, we propose a new strategy for modifying commercial LiNi_0.8Co_0.15Al_0.05O₂ by nitroxide radicals, which is generated by N-Methylpyrrolidone pyrolysis promoted by Super P carbon black (Super P). Nitroxide radicals on the surface of active materials are characterized by electron spin resonance. The nitroxide radicals modification contributes to the extra capacity, which increases the specific capacity to 267 mAh g⁻¹ at 0.1 C. This paper provides a new way to enhance specific capacity by introducing free radicals on the surface of LiNi_0.8Co_0.15Al_0.05O₂ electrode.
