NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

Disclosed is a nonaqueous electrolyte secondary battery wherein the nonaqueous electrolyte solution contains a nonaqueous solvent, a solute dissolved in the nonaqueous solvent and a hydrogenated terphenyl. The solute contains an alkali salt containing boron and another alkali salt containing no boron. The negative electrode contains a negative electrode active material composed of a randomly oriented carbon compound (A), and the randomly oriented carbon compound (A) contains a graphite carbon material (B) and a carbon material (C) which is different from the graphite carbon material (B).
