This invention provides a fully open, long-endurance Mars battery and its fabrication method. The Mars battery comprises a vertical serpentine cell, an insertable anode current collector, a mesh cathode current collector, and a dustproof and breathable membrane. The fabrication scheme is as follows: preparation and assembly of the serpentine tubular solid electrolyte, preparation and coating of a gas diffusion and gas reaction dual-functional layer, preparation and filling of a Na / K-containing liquid alloy, integration of the rod-shaped anode and mesh cathode current collectors, and encapsulation with the dustproof and breathable membrane.
