Abstract
Electrochemistry is versatile, less subject to external influences, and has great potential for the exploration of the unpredictable space environment. This work analyzes the available resources in space and discusses the application scenarios and challenges of electrochemical methods in four areas: metallurgical processing of mineral resources, water resources utilization, the carbon cycle in daily extraterrestrial life, and electrical energy storage. By examining these pivotal areas, this work elucidates the unique advantages and limitations of electrochemical technologies in space exploration. Furthermore, the paper explores the innovative application scenarios of electrochemistry in space, presenting fresh insights into how these technologies can be adapted and optimized for extraterrestrial environments. This comprehensive analysis not only provides a strategic direction for the breakthrough and advancement of electrochemical applications in space but also serves as an invaluable reference for the development of human extraterrestrial exploration and resource harvesting programs, guiding future research endeavors and technological innovations in this fascinating frontier.
