| Outline of Final Research Achievements |
Toward innovation of electric energy storage using emerging capacitive materials, three-dimensional nanostructured electrodes are developed via simple, rapid, high-yield processes. Si has a ten-times higher theoretical anode capacity than graphite. Several μm-thick, porous Si and Si-Cu alloy anodes are formed directly on Cu current collectors in 1 min from inexpensive and safe sources of their bulks via rapid vapor deposition method. Over 99.6 wt%-pure, submillimeter-long few-wall carbon nanotubes (CNTs) are produced semi-continuously via fluidized-bed method, which are ready for use without purification. CNTs are co-dispersed and co-filtrated with capacitive materials such as activated carbon, lithium cobalt oxide, and graphite to create self-supporting, tens μm-thick films. Such films work as electrodes with line contact with metal wires, and such architecture will minimize the use of heavy current collectors of metals in electrochemical capacitors and rechargeable batteries.
