Abstract:
A secondary battery includes: a cathode; an anode; and a nonaqueous electrolytic solution. The anode includes an anode active material containing an electrode compound, the electrode compound inserting and extracting an electrode reactant at a potential (a potential to lithium) of 1 V to 3 V both inclusive, and a metal salt containing one or both of a carboxylic acid compound and a sulfonic acid compound.
