Abstract
Methods and systems for producing lithium metal through room temperature electrodeposition.
Claims18
A method of producing lithium comprising:
- applying a current to an electrolytic cell comprising a cell having a cathode associated with a catholyte and an anode associated with a lithium cation-containing anolyte, the lithium cation-containing anolyte and catholyte being separated by an ion-permeable membrane;
- inducing an oxidation of the lithium cation-containing anolyte at the anode;
- flowing electrons from the anode to the cathode;
- reducing lithium cations at the cathode;
- depositing lithium metal on the cathode;
- and
- flowing lithium ions across an ion-permeable membrane from the lithium cation-containing to the catholyte.

A method of forming lithium metal nanorods comprising:
- flowing lithium ions across an ion-permeable membrane to an electrolyte associated with an electrode;
- reducing lithium cations at an electrode;
- depositing lithium metal as a plurality of lithium metal nanorods on the electrode at a temperature of 15 to 40° C.;
- wherein the lithium metal nanorods have a diameter of 250 to 350 nm and a length of up to 60 μm.
