Abstract
A negative electrode and a secondary battery including the negative electrode, the negative electrode includes a negative electrode active material layer containing negative electrode active material particles and an additive. The additive is present in an amount of 1.8 parts by weight to 3.2 parts by weight based on 100 parts by weight of the negative electrode active material particles. The additive includes at least one selected from the group consisting of Li1+m1Alm1Ti2−m1(PO4)3, wherein 0<m1≤1, Li1+m2Alm2Ge2−m2(PO4)3, wherein 0<m2≤1, Li3m3La2/3−m3TiO3, wherein 0.2≤m3≤0.05, and Li3m4La2/3−m4ZrO3, wherein 0.2≤m4≤0.05 (LATP, LAGP, LLTO, and LLZO, respectively).
