Ether/ester composite electrolyte, lithium-carbon fluoride/manganese oxide composite electrode material, preparation method and battery

The invention claims to protect an ether/ester composite electrolyte, a lithium-carbon fluoride/manganese oxide composite electrode material, a preparation method and a battery, the ether/ester composite electrolyte comprises lithium perchlorate (LiClO4) lithium salt and an electrolyte solvent, the electrolyte solvent adopts propylene carbonate (PC), ethylene glycol dimethyl ether (DME) and tetrahydrofuran (THF), the electrolyte can be used in the field of primary batteries, and the lithium-carbon fluoride/manganese oxide composite electrode material can be applied to the field of secondary batteries. Particularly, the defects of voltage lag, high cost and the like of a lithium-carbon fluoride (Li-CFx) battery are overcome. The positive electrode adopts the carbon fluoride and manganese dioxide (MnO2) composite material, so that the characteristic of high specific energy of the carbon fluoride material is reserved, the advantage of good rate capability of the manganese dioxide is also considered, and the over
