Manufacturing method of anode active material for secondary battery and manufacturing method of the secondary battery |
abstract |
The present invention is a composite of TiO 2-x -TiO 1-x N x (0<x<1) composite coating layer surrounding silicon nanoparticles and having a core-shell structure, and the TiO 2-x - TiO 1-x N x composite coating layer is TiO 2-x (0<x<1) with oxygen deficiency structure and TiO 1-x N x with rock-salt structure (0<x<1) It relates to an anode active material for a secondary battery comprising a, a method for manufacturing the same, and a method for manufacturing a secondary battery using the same. According to the present invention, TiO 2-x in order to solve the problem of low electrical conductivity of silicon, volume expansion and structural change of silicon occurring during repeated charging and discharging, which is a problem caused by silicon while including silicon having a high theoretical capacity. -TiO 1-x N x (0<x<1) High ion/electron conductivity and stable lifespan characteristics can be obtained by applying a coating layer. |
