Abstract

The capture and electrochemical conversion of CO₂ in molten LiCl-Li₂CO₃ salt is proposed. By using an inert platinum anode and a tungsten cathode, the CO₃^2- could be easily converted into carbon and oxygen gas, as well as O^2-. The released O^2- was responsible for the further capture of CO₂. Also, CO₂ could be effectively absorbed in such chloride melts with a low content of oxygen ion dissolved. In addition, the produced carbon displayed good performance as a negative electrode material for Li-ion batteries, suggesting that the process is an environmentally friendly way to convert CO₂ into energy-storage materials.
