Abstract
A liquid activated air battery includes: an electrode assembly that includes an air electrode and a metal anode; a battery container that is capable of holding the electrode assembly and electrolytic solution; a supply tank for the electrolytic solution to be supplied to the battery container; a drainage tank for the electrolytic solution discharged from the battery container; and pumps as an electrolytic solution flow mechanism that runs the electrolytic solution from the supply tank to the drainage tank through the battery container. The composition of the electrolytic solution supplied to the battery container is kept constant, and stable power output is ensured.
Claims15
A liquid activated air battery, comprising:
- an electrode assembly that comprises an air electrode and a metal anode;
- a battery container configured to hold the electrode assembly and an electrolytic solution;
- a supply tank configured to supply the electrolytic solution to the battery container;
- a drainage tank for the electrolytic solution that is discharged from the battery container;
- and
- an electrolytic solution flow mechanism that runs the electrolytic solution from the supply tank to the drainage tank through the battery container in one direction, wherein the supply tank and the drainage tank are expandable and shrinkable.

- a drainage tank for the electrolytic solution that is discharged from the battery container;
- and
- an electrolytic solution flow mechanism that runs the electrolytic solution from the supply tank to the drainage tank through the battery container in one direction, the electrolytic solution flow mechanism comprising a depressurizing means that suctions the electrolytic solution from the battery container to the supply tank;
- and
- a determination means that determines whether the liquid activated air battery has transited to a long-term halting state, wherein if the determination means determines that the liquid activated air battery has transited to the long-term halting state, the depressurizing means operates to dry an inside of the battery container.
