The invention provides a
metal lithium battery. The
metal lithium battery comprises a
battery cell, a positive
electrode tab and a negative
electrode tab, wherein the
battery cell comprises a positive pole plate, a negative pole plate and a separator membrane, the positive pole plate comprises a
positive current collector and a positive active material layer, the positive active material layer is arranged on a surface of the
positive current collector, the material of the negative pole plate is a
metal lithium thin film, the separator membrane is arranged between the positive pole plate and the negative pole plate, the positive pole plate, the separator membrane and the negative pole plate are sequentially laminated, wound or laminated and wound to form the
battery cell, the positive pole plate, the separator membrane and the negative pole plate which are sequentially laminated or wound are in
close contact without a gap, the positive
electrode tab is arranged at one side of the battery
cell and is electrically connected to the
positive current collector of the positive pole plate, the negative electrode tab is arranged at one side of the battery
cell, is formed integratedly with the negative pole plate and protrudes out of the negative pole plate, the metal
lithium battery also comprises an electronic insulation
coating layer, the electronic insulation
coating layer covers one side, at the negative electrode tab, of the positive pole plate, so that the side, at the negative electrode tab, of the positive pole plate, is in electric insulation.
