Stirling thermal battery based on thermochemical energy storage and electric ship

The invention relates to the technical field of electric ships, and provides a Stirling thermal battery based on thermochemical energy storage and an electric ship, and the Stirling thermal battery based on thermochemical energy storage comprises a gas storage tank, a reactor, a throttling element and a Stirling engine; reactants are contained in the reactor, an outlet of the gas storage tank is communicated with an inlet of the reactor, so that reaction gas is introduced into the reactor, and the reaction gas is used for being subjected to a thermal chemical reaction with the reactants; an exhaust port of the reactor is used for exhausting hot air which exchanges heat with the hot side of the Stirling engine; and the throttling element is arranged at an exhaust port of the reactor. A user can regulate and control the heat conduction rate of the Stirling engine according to the actual heat absorption requirement of the Stirling engine, and the power supply capacity of the Stirling engine to all elements in th
