Abstract: The present disclosure discloses a primary lithium battery comprising a reactive solid cathode, a liquid electrolyte, a separator, and a lithium anode. The liquid electrolyte is ionic conductive and is configured to undergo a series coupling reaction after solid phase reaction of the reactive solid cathode and the lithium anode. The liquid electrolyte comprises a solvent and an electrolyte salt, and a concentration of the electrolyte salt in the liquid electrolyte is 0.1-3 mol/L. The solvent comprises a sulfite ester type compound and an organic solvent, and a concentration of the sulfite ester type compound in the organic solvent is 5 wt % to 90 wt %.
