Method for preparing of spinel lithium titanium oxide nanofiber for negative electrode of lithium secondary battery
Disclosed is a method of preparing spinel lithium titanium oxide nanofibers for a negative electrode of a lithium secondary battery, including (s1) mixing an organic material selected from the group consisting of polyvinylpyrrolidone, polymethylmethacrylate, polyethylene, polyethylene oxide and polyvinyl alcohol, a lithium precursor, and a titanium precursor with a solvent, thus preparing a mixture solution, (s2) electrospinning the mixture solution, thus preparing composite nanofibers, and (s3) heat-treating the composite nanofibers, thus removing the organic material. In the spinel lithium titanium oxide nanofibers for a negative electrode of a lithium secondary battery prepared using the method according to the present invention, the spinel lithium titanium oxide nanofibers can provide a large surface area per unit volume, thus increasing the contact area between the electrolyte and the conductor and decreasing the lithium ion diffusion distance, thereby greatly contributing to improving electronic conductivity and ionic conductivity..

Electrode porosity for three-volt ultracapacitor
An electric double-layer ultracapacitor configured to maintain desired operation at an operating voltage of three volts, where the capacitor includes a housing component, a first and a second current collector, a positive and a negative electrode electrically coupled to one of the first and second current collectors, a separator positioned between the positive and the negative electrode, and an electrolyte in ionic contact with the electrodes and the separator. At least one of the positive electrode and the negative electrode can be made of a carbon based layer having a mesoporosity and/or a microporosity optimized for ionic mobility therewithin..

Spacer-modified graphene electrode for supercapacitor
A spacer-modified nano graphene platelet electrode, comprising: (a) multiple nano graphene platelets or sheets having an average thickness smaller than 10 nm; and (b) discrete, non-metallic nano-scaled particles that are disposed between two graphene platelets or sheets to serve as a spacer. In such a spacer-modified graphene electrode, large amounts of electrolyte-accessible pores are formed, enabling the formation of large amounts of electric double layer charges in a supercapacitor, which exhibits an exceptionally high specific capacitance..
