Proof-of-concept study develops battery that would use Martian atmosphere as fuel during discharge

Mars presents a highly complex natural environment, characterized by a variety of gas components—95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon, 0.13% oxygen, and 0.08% carbon monoxide—as well as extreme temperature fluctuations, with day-to-night temperature differences of about 60 °C.
