Classification: CPC C  H | IPC C

Claim 12:
13. A composite material, comprising:
carbon-coated hexagonal boron nitride (hBN) nanosheets and at least one polymer, said at least one polymer being one or more electrically insulating and electrochemically inert polymers, wherein the composite material possesses porosity in a range of about 47-70%, electrolyte wettability, and thermal stability,
wherein the carbon-coated hBN nanosheets comprise exfoliated hBN nanosheets; and
wherein the exfoliated hBN nanosheets are formed from bulk hBN by a liquid-phase shear exfoliation process with a polymer stabilizer of ethyl cellulose, and followed by thermal pyrolysis, thereby resulting in a carbon coating on the hBN nanosheets.
