Abstract: An apparatus having a flow cell having a first port and a second port allowing for flow of an aqueous salt solution in a flow direction from the first port to the second port or from the second port to the first port; a first electrode positioned to be in contact with the aqueous salt solution; a second electrode positioned to be in contact with the aqueous salt solution and in an electrode direction from the first electrode that is orthogonal to the flow direction; and a magnetic field generator that generates a magnetic field in a magnetic direction that is orthogonal to the flow direction and orthogonal to the electrode direction. The electrodes may be charge-storage electrodes.

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.
