An electrode for use in a device configured to remove ions from a solution. The electrode includes an intercalation material including a binary transition metal Prussian blue analogue compound, a ternary transition metal Prussian blue analogue compound, or a combination thereof. The binary compound may have a general formula: ABC[Fe(CN)], where A=Li, Na, or K; B=Mn, Fe, Ni, Cu, or Zn; C=Mn, Fe, Ni, Cu, or Zn; 0≤x≤1; 0≤y≤1; and 0≤z≤1. The ternary compound may have the general formula: ABCD[Fe(CN)], where A=Li, Na, or K; B=Mn, Fe, Ni, Cu, or Zn; C=Mn, Fe, Ni, Cu, or Zn; D=Mn, Fe, Ni, Cu, or Zn; 0≤x≤1; 0≤y≤1; 0≤z≤1; 0≤w≤1.

Water softening intercalation materials

An electrochemical deionization system that maintains an operating temperature range of a solution stream (e.g., seawater or brackish water) flowing through the cells of the electrochemical deionization system. Maintaining the operating temperature range is targeted at prolonging the lifetime of the system and increasing the overall performance of the electrochemical deionization system.

Deionization system with heat management

A device for removing ions from a solution. The device includes first and second end plates, an anion exchange membrane positioned between the first and second end plates, a first multiple of two or more first cation intercalation electrodes positioned between the first end plate and the anion exchange membrane, and one or more second intercalation electrodes positioned between the second end plate and the anion exchange membrane. The first multiple of two or more first cation intercalation electrodes and the one or more second intercalation electrodes are configured to receive an electric bias of current or voltage such that the first multiple of two or more first cation intercalation electrodes and the one or more second intercalation electrodes store and release ions from the solution.

Water deionization cells

A device for removing ions from a solution. The device includes first and second flow channels between an anion exchange membrane and first and second flow plates, respectively. The first flow channel has a first land volume positioned between the first land regions and the anion exchange membrane. The first flow channel has a first channel volume positioned between the anion exchange membrane and the first channel regions and spaced apart from the anion exchange membrane. The second flow channel has a second land volume positioned between the second land regions and the anion exchange membrane. The second flow channel has a second channel volume positioned between the anion exchange membrane and the second channel regions and spaced apart from the anion exchange membrane. The device also includes an intercalation material positioned within the first land and channel volumes or the second land and channel volumes.

Water deionization cells with flow channels packed with intercalation material

A fuel cell including an anode side including an anode, an anode side gas diffusion layer and an anode side bipolar plate formed of a first metal material, and a cathode side including a cathode, a cathode side gas diffusion layer and a cathode side bipolar plate formed of a second metal material. The fuel cell also includes a membrane having first and second sides positioned between the anode and cathode sides. The fuel cell further includes an intercalation host situated in the anode and/or cathode sides. The intercalation host is configured to intercalate metal ions formed from the first and/or second metal materials.
