Candle soot carbon cathode for rechargeable Li-CO2-Mars battery chemistry for Mars exploration: A feasibility study

A binder free approach is adopted to prepare a porous carbon cathode, made of candle soot carbon for rechargeable Li-CO2-Mars Battery Chemistry. This work demonstrates for the first time a working prototype of Li-CO2 battery technology operated at simulated Martian gases atmosphere to explore the feasibility of this technology in the Mars mission particularly with respect to surface landers and rovers.
