description A secondary battery includes a positive electrode; a negative electrode in which (A) the negative electrode includes a negative electrode active material layer containing a negative electrode active material and a negative electrode conductive agent, (B) the negative electrode active material contains a plurality of primary negative electrode active material particles and a plurality of secondary negative electrode active material particles, (C) the negative electrode active material contains a lithium titanium composite oxide, (D) a proportion of the number of the plurality of primary negative electrode active material particles to a sum of the number of the plurality of primary negative electrode active material particles and the number of the secondary negative electrode active material particles is 95% or more, (E) a median diameter D50 of the plurality of primary negative electrode active material particles is 0.1 µm or more and 1 µm or less, (F) the negative electrode conductive agent contains a plurality of flaky carbon materials, (G) an average aspect ratio of the plurality of flaky carbon materials is 6 or more and 8.5 or less, and (H) a proportion of a weight of the negative electrode conductive agent with respect to a weight of the negative electrode active material layer is 2.5% by weight or less; and an electrolytic solution.
