AB  - In this review, we examine the feasibility, core challenges, and breakthrough pathways of using molten salt electrolysis to convert CO2 into oxygen and carbon under the extreme environmental conditions of Mars. The technology uses high-temperature molten salt as the electrolyte, enabling cathodic reduction of CO2 (or CO32?) to solid carbon and anodic oxidation to oxygen. The Martian environment, characterized by low temperature, low atmospheric pressure, and low gravity, poses challenges such as thermal management, insufficient reaction kinetics, and abnormal bubble behavior at electrode interfaces. We discuss research in electrode design, electrolyte engineering, reaction device design, and system integration, providing a theoretical basis and technical path for feasible in situ resource utilization on Mars.
