Disclosed is a lithium battery. The lithium battery comprises an anode plate, a cathode current-collection base, an isolation film between the anode plate and the cathode current-collection base and an electrolyte; the anode plate comprises an anode current collector, an anode membrane attached to the anode current collector and containing an anode active material and an anode lug welded on the anode current collector; the cathode current-collection base comprises a cathode current collector and a cathode lug welded on the cathode current collector; the cathode current-collection base is a current-collection base made of a metal foil or a metal mesh with a thickness of 6-25 μm, with a thickness of 6-60 μm and having a plane or concave-convex structure; the electrolyte comprises a lithium salt and a solvent; and the lithium salt is lithium hexafluorophosphate and the concentration of the lithium salt in the electrolyte is 1.5-7 mol/L. The lithium battery of the present invention has the characteristics of high power, high energy capacity and low self-discharge rate. Meanwhile, also disclosed are a preparation method and use for the lithium battery. |
