Abstract
An apparatus to remove ions from water. The apparatus may include a stack having a first electrode including a first current collector, a spacer on top of the first electrode, and a second electrode on top of the spacer. The stack may have a tray to hold and position the stack within a housing of the apparatus and thus may improve the manufacturability of the apparatus.
Claims22
An apparatus to remove ions, the apparatus comprising:
- multiple stacks, each stack comprising:
- a first electrode,
- a second electrode, and
- a spacer, in between the first and second electrodes, allowing water to flow in between the first and second electrodes;
- wherein at least one of the stacks comprises a tray configured to hold and position the at least one stack within a housing of the apparatus and the tray comprises:
- a positioning alignment feature that is movable with the tray relative to the housing, the positioning alignment feature configured to position, on the tray, one or more selected from:
- the first electrode, the second electrode, the spacer or a charge barrier, by physical contact with the one or more selected from:
- the first electrode, the second electrode, the spacer or a charge barrier;
- and
- a rim extending substantially perpendicularly to a surface of the tray, the surface facing a surface of the first electrode, the second electrode, or both the first electrode and the second electrode.

A method of producing an apparatus to remove ions from water, the method comprising:
- manufacturing a plurality of stacks by, for each stack:
- providing a first electrode,
- providing a spacer against the first electrode, and
- providing a second electrode against the spacer,
- wherein the spacer allows water to flow in between the first and second electrodes, at least one of the stacks is made using a tray holding the at least one stack, and the tray comprises a surface facing a surface of the first electrode, the second electrode, or both the first electrode and the second electrode, and a rim extending substantially perpendicularly to the surface of the tray;
- and
- positioning the plurality of stacks including the tray having the at least one stack, within a housing of the apparatus.
