Definitions
- the carbon-based active material may include at least one selected from the group consisting of artificial graphite, natural graphite, hard carbon, soft carbon, carbon black, graphene, and fibrous carbon.
- the capacity per weight of the second negative active material may be greater than the capacity per weight of the first negative active material, and in this case, insufficient capacity or negative electrode loading due to inclination of side portions of the first negative active material layer. Deficiency can be compensated for at a more desirable level.
- the conductive material may be included in an amount of 1 to 30% by weight based on the total weight of the positive electrode active material layer.
- the solvent may include an organic solvent such as NMP (N-methyl-2-pyrrolidone), and may be used in an amount that provides a desired viscosity when the cathode active material and optionally a binder and a conductive material are included.
- NMP N-methyl-2-pyrrolidone
- the solid content including the positive electrode active material and, optionally, the binder and the conductive material may be included such that the concentration is 50 wt% to 95 wt%, preferably 70 wt% to 90 wt%.
