NOVELTY - High-capacity lithium secondary battery comprises a cathode is a lithium metal, and a positive electrode is a carbon fluoride material. The electrolyte is a solution formed by dissolving the lithium salt in the 1-methylimidazole solution at the side of the positive electrode, and the electrolyte at the opposite side is a solid electrolyte between the side electrolyte and the negative electrode. USE - The high capacity lithium secondary battery is useful in electronic products, medical appliances, national defense military industry, and other important fields. ADVANTAGE - The high capacity lithium secondary battery has high capacity.
