anode; cathode; And an electrolyte interposed between the positive electrode and the negative electrode. The positive electrode includes a positive electrode active material represented by the following Chemical Formula 1, The electrolyte is a lithium salt; And a non-aqueous solvent containing ethylene carbonate (EC). A lithium battery having an EC content of 5 to 15 parts by volume per 100 parts by volume of the non-aqueous solvent is presented: <Formula 1> Li x Ni y M 1-y O 2-z A z In Formula 1, the definitions of x, y, z, M, and A refer to the detailed description of the invention. |
