Embodiment 1
[0125] LiNi will be used as the positive electrode active material 0.8 Co 0.15 Al 0.05 O 2 , polyvinylidene fluoride as a binder, and carbon black as a conductive material were mixed in a weight ratio of 92:4:4, respectively, and then, dispersed in N-methylpyrrolidone to prepare a positive electrode active material slurry.
[0126] The positive electrode active material slurry was coated on Al foil to a thickness of 15 μm, dried at 100° C., and pressed to manufacture a positive electrode.
[0127] Graphite as an anode active material, polyvinylidene fluoride as a binder, and Ketjen black as a conductive material were mixed in a weight ratio of 98:1:1, and then, dispersed in N-methylpyrrolidone to A negative electrode active material slurry was prepared.
[0128] The negative electrode active material slurry was coated on Cu foil to a thickness of 10 μm, dried at 100° C., and pressed to manufacture a negative electrode.
[0129] The fabricated positive and negative electro...
