Abstract

An air battery includes: a cell frame of an insulating material having a bottomed frame shape in which an electrolytic solution and an anode are stored; a cathode that is disposed opposite the anode across the electrolytic solution stored in the cell frame; and a current collecting member that is electrically connected to the anode, wherein the anode and the current collecting member are electrically connected to each other via a plurality of electrically conducting members that penetrate a bottom of the cell frame.
The changes to the abstract are shown below:
An air battery includes: a cell frame of an insulating material having a bottomed frame shape in which an electrolytic solution and an anode are stored; a cathode that is disposed opposite the anode across the electrolytic solution stored in the cell frame; and a current collecting member that is electrically connected to the anode, wherein the anode and the current collecting member are electrically connected to each other via a plurality of electrically conducting members that penetrate a bottom of the cell frame.

First claim

1 . An air battery, comprising:
a cell frame of an insulating material having a bottomed frame shape, in which an electrolytic solution and an anode are stored; a cathode that is disposed opposite the anode across the electrolytic solution stored in the cell frame; and a current collecting member that is electrically connected to the anode, wherein the anode and the current collecting member are connected to each other via a plurality of electrically conducting members that penetrate a bottom of the cell frame, and the current collecting member serves as a spacer to form a ventilation space between adjacent air batteries.

2 . (canceled)

3 . The air battery according to claim 1 ,
wherein the plurality of electrically conducting members are integrally formed with the cell frame.

4 . The air battery according to claim 1 , further comprising:
a sealer disposed between the cell frame and the current collecting member.

5 . The air battery according to claim 1 , further comprising:
wherein the anode and each of the plurality of electrically conducting members are connected to each other by an electrically conductive double-sided tape.

6 . The air battery according to claim 1 further comprising:
a metal foil disposed between the anode and the plurality of electrically conducting members.

7 . The air battery according to claim 1 further comprising:
a metal foil disposed between the current collecting member and the plurality of electrically conducting members.

8 . The air battery according to claim 1 wherein the current collecting member is integrated with the plurality of electrically conducting members so as to have functions of both of the current collecting member and the plurality of electrically conducting members.

9 . The air battery according to claim 1 wherein both of the plurality of electrically conducting members and through holes in the bottom of the cell frame where the plurality of electrically conducting members penetrate have a long continuous shape.

10 . The air battery according to claim 1 wherein both of the plurality of electrically conducting members and through holes in the bottom of the cell frame where the plurality of electrically conducting members penetrate have a short intermittent shape.

11 . (canceled)

12 . A battery pack, comprising:
a stacked plurality of an air battery including:
a cell frame of an insulating material having a bottomed frame shape, in which
an electrolyte solution and anode are stored; a cathode that is disposed opposite the anode across the electrolytic solution stored in the cell frame; and a current collecting member that is electrically connected to the anode, wherein the anode and the current collecting member are connected to each other via plurality of electrically conducting members that penetrate a bottom of the cell frame and the anode, and the current collecting member serves as a spacer to form a ventilation space between adjacent air batteries.
