  "textContent": "A lithium secondary battery having a positive electrode, a separator, a negative electrode facing the positive electrode with the separator interposed therebetween, and an electrolyte, in which metallic lithium deposits on the negative electrode during charge. The electrolyte includes: an oxalate salt containing an oxalate complex as an anion, and a lithium ion as a cation; and a dicarboxylic acid diester compound. The dicarboxylic acid diester compound is contained in an amount of 0.1 mass% or more and less than 10 mass% in the electrolyte.",
