Abstract: A method of improving interfacial contact at an electrode-to-solid-electrolyte interface in a solid-state battery cell is provided. The method includes providing a solid-state battery cell including a solid-state electrolyte and electrodes defining an anode and a cathode. Each of the anode and cathode are adjacent to the solid-state electrolyte at an interface. The method further includes electrochemically increasing interfacial contact between at least one of the electrodes and the solid-state electrolyte by applying a voltage pulse to the cell at a high current density for a short duration, wherein electrode material diffuses into pores formed in the solid electrolyte interface, thereby healing the pores and eliminating an interfacial space charge effect.

Abstract: A method of reviving a lithium-ion battery cell in which dendrites are formed providing a lithium-ion battery cell including a lithium-metal-containing electrolyte and one of a graphite or a lithium-metal-containing anode. Lithium dendrites are formed at an anode/electrolyte interface in the cell and extend into the electrolyte of the cell. The method further includes electrochemically healing the battery cell by actively applying a plurality of continuous low current density galvanostatic charge-discharge cycles to the battery cell. Lithium metal is thusly oxidized from tips of the dendrites thereby causing dissolution of the dendrites.

Abstract: A positive electrode for a sodium ion battery is provided. The positive electrode includes a sodium metal vanadium fluorophosphate having a formula according to Formula I: Na3V2-xMxOy(PO4)2F3-y??I; wherein 0<x?1, 0?y?1, and M is one or more additional metals.

Abstract: A super ion conductor composition is disclosed. The super ion conductor composition has the general formula: A1+xMx/2Zr2?x/2(PO4)3, where each A is independently Na or Li, M is Mn or Mg, and subscript x is from 0.5 to 3. A solid electrolyte comprising the super ion conductor composition, and a method of preparing the solid electrolyte, are also disclosed. The method comprises combining a zirconium compound, a manganese or magnesium compound, a sodium compound, and a phosphate compound to give a mixture; and calcining the mixture to give the super ion conductor composition, thereby preparing the solid electrolyte. Functional materials and devices comprising the super ion conductor composition are also disclosed, including a catholyte composition, an ion conducting solid electrolyte membrane, as well as all-solid-state batteries.
