Abstract

Provided is a tape-shaped electrode that can effectively perform discharging and recharging even if the size thereof is increased. The tape-shaped electrode includes a plurality of conductive plates, and insulating coupling members that separably couple the plurality of conductive plates arranged in one direction in an insulating state.

First claim

The invention claimed is:

1. A metal-air battery comprising:
an electrolyte solution tank that accommodates an electrolyte solution;
a plurality of electrode rollers that are provided in the electrolyte solution in the electrolyte solution tank;
the tape-shaped electrode which comes into electrical contact with the plurality of electrode rollers and is stretched by the plurality of electrode rollers in the electrolyte solution; and
an air electrode that is provided in the electrolyte solution tank to face the tape-shaped electrode between the plurality of electrode rollers.

2. The metal-air battery according to claim 1 ,
wherein three or more electrode rollers are provided in the electrolyte solution tank in one line, and
wherein the air electrodes are provided in all portions between the electrode rollers.
