A seawater battery has been provided which includes an anode and a cathode, the anode being a flexible sheet of anode material and the cathode being a flexible foil of cathode material. An insulative flexible film joins one side of the cathode foil to one side of the anode sheet so as to form a flexible bilaminar composite. A device is operatively associated with the bilaminar composite for providing it positive buoyancy in seawater, and a ballast device is connected to a bottom edge of the bilaminar composite. An electrical lead is connected to the anode sheet and an electrical lead is connected to the cathode foil at a common edge of the bilaminar composite and in close proximity to one another. The bilaminar composite is flexed to a compacted condition, and a device is provided for releaseably retaining the bilaminar composite in the compacted flexed condition. With this arrangement the battery can be placed in seawater and when the retaining device is released the bilaminar composite will unflex and electrical current will be produced across the electrical leads.
