The invention relates to the technical field of secondary batteries, in particular to calcium salt electrolyte and electrolyte as well as a preparation method and application thereof. The calcium salt electrolyte is obtained by completely reacting an organic solvent, metal calcium and a salt containing cations capable of being reduced by the metal calcium in the same container under the protection of inert gas, and the calcium salt electrolyte is obtained by removing the organic solvent in the prepared calcium salt electrolyte. Or reducing the solubility of the calcium salt in the organic solvent, and separating out the calcium salt solute. The preparation method has the advantages of cheap and easily available raw materials, short time, high efficiency, thorough reaction, high purity and easy separation and recovery of by-products. Moreover, the prepared calcium salt electrolyte and electrolyte are high in purity, and the problem that the calcium salt electrolyte and electrolyte required by the calcium ion b
