METHOD FOR GENERATING NANOFIBER SHEETS OF LITHIUM TITANIUM OXIDE-CARBON HYBRID COMPOSITE, NANOFIBER SHEETS USING THEREOF, LITHIUM ION BATTERY AND HYBRID SUPERCAPACITOR HAVING NANOFIBER SHEETS

摘要

PURPOSE: A method for fabricating a lithium titanium oxide-carbon composite nanofiber sheet is provided to improve electric conductivity. CONSTITUTION: A method for fabricating a litium titanium oxide-carbon composite nanofiber sheet(400) comprises: a step of mixing a lithium source material(10), a titanium source material(20), an oxidizer, a first polymer material(40), and a solvent(50) to prepare an intermediate mixture; a step of preparing a nano fiber sheet from the intermediate by electrospinning; a step of performing a second polymer material(60); and a step of performing thermal treatment of the nano fiber sheet. The solvent is distilled water, N,N-dimethyl formamide, N,N-diethyl formamide, dimethyl sulfoxide, or N-methyl pyrrolidone.
