PROBLEM TO BE SOLVED: To provide a solid electrolyte lithium secondary battery with high cycle characteristics. SOLUTION: A solid electrolyte lithium secondary battery uses a lithium- containing transition metal oxide in a positive electrode 1, a carbon material capable of storing/releasing lithium in a negative electrode 2, and a polymer solid electrolyte or a gel electrolyte as the electrolyte, and the negative electrode 2 is made of at least one mixture of graphite base carbon having a spacing of planes d002 of 3.4 Å or less and a crystallite size in the direction of (c) axis Lc of 300 Å or more, and a non-graphite base carbon having a spacing of planes d002 of 3.4 Å or more and a crystallite size in the direction of (c) axis Lc of 50 Å or less. |
