  • Patent number: 9722284
    Abstract: A nonaqueous secondary battery includes an ion supply unit which supplies ions identical to ions in an electrolyte into the electrolyte at a reaction potential higher than the uncharged potential of a positive electrode. The ion supply unit includes an ion supply source which elutes the ions into the electrolyte by being in contact with the electrolyte in a state of being electrically connected to the positive electrode, and a first covering portion which covers at least a part of the ion supply source. Then, the first covering portion maintains the ion supply source and the positive electrode in an electrically disconnected state by being interposed between the ion supply source and the positive electrode, and is dissolved or disappears at the reaction potential.
