Abstract
Electrodes having associated therewith a protective porous film or coating of boron nitride nanotubes (BNNTs).
Claims21
A sulfur (S) based electrode for an energy storage device having a film of a composite of boron nitride nanotubes (BNNTs) and at least one polymeric binder, wherein the film of the composite intimately contacts at least one surface of the S electrode as a porous network which is selectively permeable to transport metal ions and electrolyte used in the energy storage device but impermeable to polysulfides.
16-25. (canceled)
A sulfur (S) based cathode electrode comprising a sulfur-cathode material having associated therewith a porous film or a porous deposit of boron nitride nanotubes (BNNTs),
- wherein the film of composite has an average thickness of from about 0.9 microns to about 5 microns as determined by SEM, and
- wherein the film of composite has an areal density or BNNT loading of from about 0.1 mg cm−2 to about 3.5 mg cm−2.
