Abstract
According to one embodiment, a negative electrode active material includes particles and a carbon material. The particles is represented by LiATiBO, where A is at least one element selected from the group consisting of Na, K, Mg, Ca, Ba, and Sr; B is a metal element other than Ti; and a, b, c, and d respectively satisfy 0≤a≤5, 0≤b≤6, 0≤c≤0.6, and 0≤d≤3. The carbon material covers at least a part of surfaces of the particles.
