NOVELTY - A high-safety primary lithium-manganese battery comprises positive electrode sheet, negative electrode sheet, ceramic separator, electrolyte comprising lithium salt and organic solvent, and battery shell. The positive electrode sheet, ceramic separator, pre-lithiated negative electrode sheet and ceramic separator are repeatedly laminated in order to form dry battery core. The primary lithium-manganese battery is made by placing dry battery core into battery shell and injecting electrolyte, aging, sealing and aging. The negative electrode sheet is electrochemically pre-doped with lithium to convert fully-charged secondary lithium battery negative electrode sheet or zero-charged lithium/carbon half-cell positive electrode sheet into pre-lithiated negative electrode sheet. The positive and negative sides of positive electrode sheet are provided with positive electrode reserved lugs and pre-lithiated negative electrode sheet is provided with negative electrode reserved lugs on both sides. USE - High-safety primary lithium-manganese battery. ADVANTAGE - The high-safety primary lithium-manganese battery has no problems of fire, deflagration, or explosion after impact, extrusion and puncture tests. DETAILED DESCRIPTION - A high-safety primary lithium-manganese battery comprises positive electrode sheet, negative electrode sheet, ceramic separator, electrolyte and battery shell. The positive electrode sheet, ceramic separator, pre-lithiated negative electrode sheet and ceramic separator are repeatedly laminated in order to form dry battery core. The primary lithium-manganese battery is made by placing dry battery core into the battery shell and injecting electrolyte, aging, sealing and aging. The negative electrode sheet is electrochemically pre-doped with lithium to convert the fully-charged secondary lithium battery negative electrode sheet or zero-charged lithium/carbon half-cell positive electrode sheet into pre-lithiated negative electrode sheet. The positive and negative sides of the positive electrode sheet are provided with positive electrode reserved lugs and pre-lithiated negative electrode sheet is provided with negative electrode reserved lugs on both sides. The dry battery core comprises positive electrode tab and negative electrode tab, when several of positive electrode sheet are stacked, the positive electrode reserved lugs are aligned with each other and formed into the multiple positive electrode tab, the multiple positive electrode tab and flat metal foil current collector are welded to form positive electrode tabs. When several of pre-lithiated negative electrode sheets are stacked, the negative electrode reserved lugs are aligned with each other and formed into the multiple negative electrode tabs, the multiple negative electrode tabs and flat metal foil current collector are welded to form negative electrode tabs. The ceramic separator is nano-microporous ceramic separator having high mechanical strength, high porosity and high wettability.
