摘要：

Li-CO2/O2 battery presents a promising solution to combine CO2 utilization and electrochemical energy storage. Herein, Pt nanoparticles (NPs) of 2.5 nm in mean size loaded uniformly on carbon nanotubes (Pt/CNT) were synthesized and served as cathodic catalysts. The Li-CO2/O2 battery with Pt/CNT catalyst were investigated in mixture gas of CO2 and O2 with O2 content varying from 0% to 20%. It has revealed that the Li-CO2/O2 (2% O2) battery, i.e., operating with 2% O2 content, displays a minimum overpotential of 0.31 V and a cycling stability of ...
