Abstract

A battery includes a can having a rectangular or triangular cross section, the can having a closed end and an open end, a cathode in the can, an anode in the can, a separator between the cathode and the anode, and a seal assembly attached to the open end of the can.

Claims (27)

1. A battery, comprising:

a can having a longitudinal axis, a length that is parallel to the longitudinal axis, and a cross section relative to the longitudinal axis that is rectangular for substantially the entire length of the can, the can having a closed end and an open end;

a cathode in the can;

a conductive hot melt material between the cathode and the can;

an anode in the can;

a separator between the cathode and the anode; and

a seal assembly attached to the open end of the can,

wherein the seal assembly comprises a seal and a current collector attached to the seal.

2. A battery, comprising:

a can having a longitudinal axis, a length that is parallel to the longitudinal axis, and a cross section relative to the longitudinal axis that is rectangular for substantially the entire length of the can, the can having a closed end and an open end;

a cathode in the can;

an anode in the can;

a separator between the cathode and the anode;

a seal assembly attached to the open end of the can; and

a non-conductive melt between the cathode and the seal assembly.

3. A method of making a metal-air battery, the method comprising:

placing a cathode tube in a can having a longitudinal axis, a length that is parallel to the longitudinal axis, a cross section relative to the longitudinal axis that is rectangular for substantially the entire length of the can, and an air access opening, the can having a closed end and an open end;

placing an anode in the can;

placing a seal assembly across the open end of the can;

sealing a portion of the can over the seal assembly; and

placing a conductive melt in the can.

4. A method of making a metal-air battery, the method comprising:

placing a cathode tube in a can having a longitudinal axis, a length that is parallel to the longitudinal axis, a cross section relative to the longitudinal axis that is rectangular for substantially the entire length of the can, and an air access opening, the can having a closed end and an open end;

placing an anode in the can;

placing a seal assembly across the open end of the can;

sealing a portion of the can over the seal assembly; and

placing a non-conductive melt between the cathode and the seal assembly.
