Abstract
The problem of the present invention is to provide a sodium ion battery system capable of intending higher capacity. The present invention solves the above-mentioned problem by providing a sodium ion battery system comprising a sodium ion battery and a charge control unit, wherein the anode active material is an active material having an Na2Ti6O13 crystal phase, and the above-mentioned charge control unit controls electric current and electric potential of the above-mentioned anode active material so as to cause a second Na insertion reaction on the lower electric potential side in addition to a first Na insertion reaction in the above-mentioned Na2Ti6O13 crystal phase.
