Abstract
Electrolyte materials for use in electrochemical cells, electrochemical cells comprising the same, and methods of making such materials and cells, are generally described. In some embodiments, the materials, processes, and uses described herein relate to electrochemical cells comprising sulfur and lithium such as, for example, lithium sulfur batteries.
Claims15
An electrochemical cell, comprising:
- a first electrode comprising lithium metal;
- a second electrode;
- a lithium bis-oxalatoborate salt;
- and
- at least one of a lithium nitrate salt, a guanidium nitrate salt, and a pyridinium nitrate salt.
2 more elements
An electrochemical cell, comprising:
- an anode comprising lithium as the active anode species;
- a cathode comprising an active cathode species;
- and
- an electrolyte comprising a non-fluid material positioned between the anode and the cathode, and an auxiliary material absorbed by the non-fluid material;
- wherein the non-fluid material comprises a branched polyimide;
- and
- wherein the non-fluid material, in combination with the absorbed auxiliary material, has a yield strength greater than that of lithium metal.
