Recent advancement in designing catalysts for rechargeable Li–CO2 batteries

Abstract

Rechargeable Li–CO2 batteries have attracted tremendous attention, owing to their properties of productive CO2 fixation, and energy storage and conversion. However, insulating and thermodynamically stable discharge products (e.g. Li2CO3) lead to sluggish CO2 reduction/evolution kinetics, low energy density, high overpotential and limited cycling life of the batteries, which restrict the development and application of practical Li–CO2 batteries. To resolve these issues, it is essential to explore efficient cathodic catalysts that can either prevent Li2C2O4 disproportionation reactions to generate Li2CO3 or enhance the CO2 evolution reaction. In this review, the primary focus is on the designing of cathodic catalysts, which include precious metal-based materials, carbon-based materials, transition metal-based materials and soluble catalysts. Updated research achievements in the field of cathodic catalysts are summarized. Furthermore, based on a comprehensive overview of the state of research progress, some innovative perspectives and critical scientific challenges are also put forward for the practical application of Li–CO2 batteries.
