| titleOfInvention | Anode active material for lithium secondary battery and lithium secondary battery comprising same |
| abstract | The present invention relates to a negative electrode active material for a lithium secondary battery and a lithium secondary battery comprising the same. The present invention provides a negative electrode active material for a lithium secondary battery including a metal oxide-carbon composite material modified with a metal oxide, wherein the metal oxide is reduced to metal by insertion of lithium ions during initial charging, and a lithium secondary battery including the same. . According to the present invention, a metal oxide is assembled into a cell together with carbon in an oxide state, and then reduced to a metal by insertion of lithium ions during initial charging, and high capacity and excellent repeated charge / discharge due to the interaction of the reduced metal and carbon Has characteristics. At this time, in reducing the metal oxide, the heat treatment process (reduction process) by high temperature is excluded, and even in the case of a metal having a low melting point, the metal oxide is reduced to nanometer (nm) size to be easily combined with carbon, and the use of metal is limited. Instead, the manufacturing process is shortened. In addition, the initial capacity is high, and the capacity decrease due to repeated charging and discharging is small, and thus the capacity is high even after several charge and discharge cycles. |
