Abstract
A method of making a cathode assembly for a metal-air battery includes extruding a composition having a catalyst, a fibrillatable material, and a lubricant, to form an extrudate; calendering the extrudate; connecting the extrudate to a current collector; and heating the extrudate to remove at least a portion of the lubricant to make the cathode assembly. The method can further include laminating a separator to the cathode assembly.

A method of making a cathode assembly, the method comprising:
- extruding a composition comprising a catalyst, a fibrillatable material, and a lubricant, to form an extrudate;
- calendering the extrudate;
- laminating the extrudate to a current collector;
- and
- heating the extrudate to remove at least a portion of the lubricant.
A method of making a cathode for a metal-air battery, the method comprising:
- extruding a composition comprising a catalyst, a fibrillatable material, and a lubricant, to form an extrudate;
- calendering the extrudate between rollers;
- and
- pressing the extrudate to a current collector between rollers.
A method of making a metal-air battery, the method comprising:
- making a cathode assembly by:
- extruding a composition comprising a catalyst, a fibrillatable material, and a lubricant to form an extrudate;
- calendering the extrudate;
- connecting the extrudate to a current collector;
- and
- heating the extrudate to remove at least a portion of the lubricant to make the cathode assembly;
- placing the cathode assembly in a housing comprising air access openings such that air entering the housing contacts the cathode assembly;
- placing a separator adjacent to the cathode assembly;
- and
- placing an anode adjacent to the separator.
