Beschreibung
Zusammenfassung:	A secondary battery is disclosed, which is provided with: a positive electrode collector; a negative electrode collector; a positive electrode electrolyte solution part that contains a positive electrode electrolyte solution and that is disposed between the positive electrode collector and the negative electrode collector such as to contact the positive electrode collector; and a negative electrode electrolyte solution part that contains a negative electrode electrolyte solution and that is disposed between the positive electrode collector and the negative electrode collector such as to contact the negative electrode collector. The positive electrode electrolyte solution contains an electrolyte salt and a nonaqueous solvent containing a first solvent, and the negative electrode electrolyte solution contains an electrolyte salt and a nonaqueous solvent containing a second solvent. The second solvent has a reduction potential that is lower than the potential of the negative electrode. 本发明公开一种二次电池，其具备：正极集电体；负极集电
