Abstract

Li-ion batteries are the dominant commercial rechargeable batteries nowadays, which are used in electronic devices and electrified transportation widely. However, undesirable energy density of Li-ion batteries prohibits them from meeting requirements of new generation electronic devices. Therefore, it is important to find more alternative electronic energy storage systems with higher capacity. Fortunately, Li-CO2 batteries, featured high capacity and ability to convert CO2, have become a promising candidate to replace Li-ion batteries. In addition, Li-O2 batteries also attract people’s attention due to their high energy density and low cost. However, Li-CO2 batteries and Li-O2 batteries both face challenges of terrible cycle performance and poor reversibility. These problems are caused by the accumulation of their stable discharged product. Therefore, we design a series of transition metal oxides electrocatalysts to improve electrochemical performance. Furthermore, we performed different technologies to investigate reaction mechanism of these electrocatalysts
