The invention relates to a soft
current collector and a
lithium-
ion battery made of a soft
current collector, which is characterized in that the manufacturing method is as follows: first, the positive
electrode is prepared: the positive
electrode slurry is coated on the aluminum layer with a thickness of 0.1-10.0 μm, and the thickness of the plastic is 5.0~30.0μm aluminized plastic, the
coating thickness is 0.08~0.20mm, after
drying in a vacuum oven at 80~120oC, the positive
electrode sheet is obtained; the negative electrode is prepared and the negative electrode
slurry is coated on the
copper layer with a thickness of 0.2~8.0μm , On the
copper-plated plastic with a plastic thickness of 5.0~30.0μm, the
coating thickness is 0.06~0.15mm, and the negative electrode sheet is obtained after
drying in a vacuum oven at 80~120oC; the positive electrode sheet, PP or PE separator, and the negative electrode are sequentially The pole pieces are stacked and packed with aluminum-
plastic film, and an appropriate amount of
electrolyte solution 1MLiPF6+EC:DMC (1:1) is injected into the glove box; the aluminum-
plastic film is hot-pressed and packaged to obtain a flexible
lithium-
ion battery. It effectively improves the
mass energy density of the
battery cell. The cost of the battery
monomer is reduced; it has the advantages of low price, because the shape of the
lithium-
ion battery prepared by it can be arbitrary, ultra-thin, and the
mass energy density is high.
