1. A dynamic isotope battery, comprising:
a metallic canal;
a housing, defining a chamber for accommodating a heat source and provided with a non-return valve, two opposite ends of the housing being communicated with two ends of the metallic canal respectively to form a closed circulation loop;
a fuel cartridge fixedly disposed within the housing;
a radioactive source contained in the fuel cartridge;
a liquid metal provided in the circulation loop;
a piezoelectric transduction component disposed on an inner surface of the metallic canal;
a heat dissipation structure, provided at an outer surface of the metallic canal and spaced apart from the piezoelectric transduction component along an axial direction of the metallic canal; and
an electromagnetic pump, provided at the metallic canal for driving circular flow of the liquid metal.
