The present invention provides a magnesium ion battery and a preparation method therefor. The magnesium ion battery comprises a battery negative electrode, an electrolyte solution, a separator, and abattery positive electrode. The battery positive electrode comprises a positive electrode current collector and a positive electrode active material layer. The positive electrode active material layercomprises a positive electrode active material, and the positive electrode active material layer comprises a positive electrode active material capable of freely and reversely deintercalating magnesium ions. The electrolyte solution comprises electrolyte and a solvent. The electrolyte is a magnesium salt. The battery negative electrode comprises one or more of a metal, a metal alloy or a metal composition conductive material. The present invention provides a magnesium ion battery in which lithium is replace by magnesium, thereby resolving the problem of shortage of lithium resource reserves;the volume and the weight o
