摘要： The present disclosure relates to a negative electrode active material having excellent output characteristics and causing little gas generation, and an electrode including the negative electrode active material. The negative electrode active material includes metal oxide-lithium titanium oxide (MO-LTO) composite particles which have a shape of secondary particles formed by aggregation of primary particles, wherein the primary particles have a core-shell structure including a core and a shell totally or at least partially covering the surface of the core, the core includes primary particles of lithium titanium oxide (LTO), and the shell includes a metal oxide.
