A secondary battery charged and discharged even after dissolution. The active material in the cathode body and/or the anode body is a liquid, or the active material undergoes phase transition into a liquid is provided. The secondary battery ( 1 ) includes: a cathode collector ( 2 ), a cathode body ( 3 ), a solid electrolyte ( 4 ), an anode body ( 5 ), and an anode collector ( 6 ). The cathode body and the anode body are sealed by the solid electrolyte, the cathode collector, and/or the anode collector. The cathode body and the anode body preferably contain an active material that undergoes phase transition from a solid to a liquid, or to a phase containing a liquid, due to charge and discharge. The cathode body or the anode body preferably contains a liquid active material. A polymeric layer may be inserted between the cathode body and/or the anode body and the solid electrolyte. |
