Abstract
A method of making an electrode by providing a mixture of first particles of silver or silver oxide and second particles of an inorganic porogen, molding the mixture, cohering the mixture to form a green body, demolding the green body, heating the green body to form a monolith, to convert any silver oxide to silver, and to fuse the first particles together, and submerging the monolith in a liquid that removes the second particles.
Claims13
An electrode made by a method comprising:
- providing a mixture comprising:
- first particles comprising silver or silver oxide;
- second particles comprising an inorganic porogen;
- and
- aqueous potassium hydroxide;
- molding the mixture;
- cohering the mixture to form a green body;
- wherein molding and cohering the mixture includes incorporating a current collector into the green body;
- demolding the green body;
- heating the green body to form a monolith, to convert any silver oxide to silver, and to fuse the first particles together;
- and
- submerging the monolith in a liquid that removes the second particles.
A method comprising:
- providing a mixture comprising:
- first particles comprising silver oxide;
- and
- second particles comprising an inorganic porogen;
- molding the mixture;
- cohering the mixture to form a green body;
- demolding the green body;
- heating the green body to form a monolith, to convert the silver oxide to silver, and to fuse the first particles together;
- and
- submerging the monolith in a liquid that removes the second particles.
A method comprising:
- providing a mixture comprising:
- first particles comprising metallic silver;
- wherein the first particles have a particle size of less than 50 microns;
- and
- second particles comprising an inorganic porogen;
- molding the mixture;
- cohering the mixture to form a green body;
- demolding the green body;
- heating the green body to form a monolith and to fuse the first particles together;
- and
- submerging the monolith in a liquid that removes the second particles.
