Abstract: The present disclosure is generally related to separators for use in lithium metal batteries, and associated systems and products. Certain embodiments are related to separators that form or are repaired when an electrode is held at a voltage. In some embodiments, an electrochemical cell may comprise an electrolyte that comprises a precursor for the separator.

Abstract: Water deionization systems based on electrochemical water desalination or softening using a capacitive or intercalative deionization devices including a stack of electrochemical cells. Each cell includes first and second electrodes and an ion exchange membrane. Each cell includes inlet and outlet channels with control valves that control the separation of the source water into brine (e.g., concentration) and clean water (e.g., purification) streams. The deionization device or module may include multiple electrochemical cells connected electrically in series, parallel or a combination of both. The cells may also be in serial, parallel, or combined fluid communication. The output water of one or more streams from each cell or collection of cells may be recirculated and combined with one or more input water streams to improve the electrochemical energy efficiency of the cells. The electrochemical cells at different rows may have varying electrode thickness, area and loading of the active material.

Abstract: 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: AxByCz[Fe(CN)6], 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: AxByCzDw[Fe(CN)6], 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.

Abstract: The invention comprises an anode-free lithium metal cell having an anode-side current collector composed of lithium, a lithium alloy or lithium-containing compound or a transition metal having a lithium or lithium alloy or lithium-containing compound surface coating, to provide a specific energy of the cell of 350 Wh/kg or greater.
