Claims7
A battery comprising:
- a positive electrode;
- a negative electrode containing graphite;
- and
- an electrolyte solution containing 2,2′-bipyridyl,
- wherein a molar ratio M1/M2 is less than 4.02×10−5,
- where M1 is a molar amount of the 2,2′-bipyridyl contained in the electrolyte solution and M2 is a molar amount of the graphite contained in the negative electrode.
