Abstract
The present invention 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.
Claims38
A rechargeable electrochemical cell comprising:
- a first electrode;
- a second electrode;
- and
- an electrolyte positioned between the first electrode and second electrode, wherein the electrolyte comprises fluorinate compounds dissolved with a salt so when the electrolyte interacts with the first electrode or second electrode it decomposes into ionic compounds enriching a solid-electrolyte-interface (SEI) of the first electrode or second electrode

A method of operating a cell comprising:
- arranging a first electrode;
- arranging a second electrode;
- and
- positioning an electrolyte between the first electrode and second electrode, wherein the electrolyte comprises fluorinate compounds dissolved with a salt so when the electrolyte interacts with the first electrode or second electrode it decomposes into ionic compounds enriching a solid-electrolyte-interface (SEI) of the first electrode or second electrode.
