| abstract |
The present invention relates to an anode active material having excellent output characteristics and little gas generation, and an electrode containing the anode active material. The negative electrode active material comprises MO-LTO composite particles (metal oxide (MO)-lithium titanium oxide (LTO) composite particles), wherein the composite particles have the form of secondary particles in which primary particles are aggregated, the The primary particles have a core-shell structure in which the core is at least partially or completely covered by a shell, the core being a primary particle of lithium titanium oxide (LTO), the shell comprising a metal oxide. |
