Abstract:

Due to the ability of capturing and converting carbon dioxide into energy storage materials, Li-CO2 battery can not only reduce carbon dioxide emission, but also serve as an innovative energy storage device, so it has attracted extensive attentions from researchers. In this review, the working mechanism, development history and existing problems of Li-CO2 battery were briefly introduced. Based on the summary of the current research works and the performance comparison of various batteries, different types of catalysts were systematically classified and briefly summarized, the design concept and research status of the cathode catalysts were reviewed, the problems and challenges for these catalysts were proposed, and the future research directions of cathode catalysts for Li-CO2 batteries were also presented. It was indicated that high-performance cathode catalysts is the key factor to promote the electrochemical reaction kinetics, and reduce the charge platform and overpotential of Li-CO2 battery.

Key words: Li-CO2 batteries, air electrode, catalyst, nanomaterials, electrochemistry
