  "textContent": "A non-aqueous electrolyte secondary cell comprising a negative electrode () having a negative electrode collector () and a negative electrode active material layer () provided on the negative electrode collector (). The negative electrode active material layer () contains graphite particles A and graphite particles B as negative electrode active materials. The graphite particles A have an internal void rate of 5% or less. The graphite particles B have an internal void rate of 8 to 20%. When the negative electrode active material layer is halved in the thickness direction, a region on the half closer to the outer surface contains more graphite particles A than a region on the half closer to the negative electrode collector.",
