Abstract
The present disclosure relates to a method of making an electrochemically active material, which comprises metal nanostructures encapsulated in LaF3 shells. The electrochemically active material may be included in an electrode of an F-shuttle battery that includes a liquid electrolyte, which, optionally, allows the F-shuttle batteries to operate at room temperature.
Claims17
A method of making a core shell structure, the method comprising:
- dispersing a metal nanostructure in a first organic solvent to form a first suspension;
- adding a first amount of a quaternary amine salt to the first suspension;
- adding a lanthanum salt solution to the first suspension, wherein the lanthanum salt solution comprises a lanthanum salt and water;
- removing the water from the first suspension to form a first organic solvent layer;
- adding a second amount of a quaternary amine salt to the first organic solvent layer to form a second suspension;
- adding a fluoride source solution to the second suspension to form a LaF3 shell on the metal nanostructure, wherein the fluoride source solution comprises a fluoride source and water;
- removing the water from the second suspension to form a second organic solvent layer;
- and
- adding a second organic solvent to the second organic solvent layer to distribute the metal nanostructure having a LaF3 shell.
