NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND USE OF SAME

摘要

A nonaqueous electrolyte secondary battery provided by the present invention comprises a positive electrode and a negative electrode. The positive electrode has a positive electrode active material layer that contains a positive electrode active material as a main component, and the negative electrode has a negative electrode active material layer that contains a negative electrode active material as a main component. The ratio of the linseed oil absorption (B) (mL/100 g) of the negative electrode active material relative to the DBP oil absorption (A) (mL/100 g) of the positive electrode active material, namely B/A is from 1.27 to 1.79.
