Lithium battery and the preparation method thereof
The present invention discloses a lithium battery, which comprises of a positive electrode plate, a negative electrode current collector substrate, a separator and electrolyte between the positive electrode plate and the negative electrode current collector substrate. The positive electrode plate comprises a positive electrode collector, a positive electrode active material-containing positive electrode layer attached to the positive electrode collector and positive electrode tab welded to the positive electrode collector. The negative electrode current collector substrate comprises a negative electrode current collector and negative electrode tab welded to the negative electrode current collector. The negative electrode current collector substrate is a current collector substrate with 6˜60 μm thickness having a planar or concavo-convex structure which is made from metal foil material or metal mesh with 6˜25 μm thickness. The electrolyte contains lithium salt and solvent, wherein the lithium salt is lithium hexafluorophosphate and its concentration in the electrolyte is between 1.5˜7 mol/L. The lithium battery of the present invention has characteristics of high power, high energy and low self-discharge rate. Meanwhile, the present invention also discloses a preparation method of the lithium battery and use thereof.
