The Li-CO2 battery with the concept of turning waste into treasure has aroused great scientific research enthusiasm recently, but unfortunately it is a long shot for the large-scale applications of Li-CO2 battery due to its huge overpotential and poor cycling life at current stage. Herein, NiO nanosheets engineered by O vacancy growing vertically on C clothes (NiO-Vo@CC) was developed as viable catalyst for both CO2 reduction reaction (CO2RR) and CO2 evolution reaction (CO2ER) in Li- CO2 system. The O vacancy decorated by surplus electron will not only work as electron donor (Lewis base) surface to activated the electron-deficient C atom in CO2 but also narrow the band gap of NiO, therefore optimized CO2 conversion kinetic can be obtained by using defective NiO-Vo@CC electrode. The use of defect engineering to achieve performance improvement in aprotic Li-CO2 battery is still in its infancy at current stage and thus the authors’ research initially corroborates that modulation of the surface property via defect engineering can serve as valid strategy to design high performance electrodes for Li-CO2 battery.
