Non-aqueous electrolyte secondary cell |
| abstract |
A non-aqueous electrolyte secondary cell comprising a negative electrode (12) having a negative electrode collector (40) and a negative electrode active material layer (42) provided on the negative electrode collector (40). The negative electrode active material layer (42) 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 42 is halved in the thickness direction, a region 42b on the half closer to the outer surface contains more graphite particles A than a region 42a on the half closer to the negative electrode collector. |
