| 摘要 |
The present invention relates to a high-voltage lithium secondary battery having improved life characteristics. Specifically, the high-voltage lithium secondary battery having improved life characteristics comprises: an anode comprising lithium nickel manganese complex oxide (LNMO) wherein lithium ions can be inserted thereinto and removed therefrom as an anode active material; a cathode comprising a carbon-based material wherein lithium ions can be inserted thereinto and removed therefrom and titanium oxide coated on the surface of the carbon-based material as a cathode active material; a separation film disposed between the anode and the cathode; and a non-aqueous electrolyte containing lithium salt. |
