  • Publication number: 20120107594
    Abstract: Disclosed is a single wall carbon nanotube (SWCNT) film electrode (FE), all-organic electroactive device systems fabricated with the SWNT-FE, and methods for making same. The SWCNT can be replaced by other types of nanotubes. The SWCNT film can be obtained by filtering SWCNT solution onto the surface of an anodized alumina membrane. A freestanding flexible SWCNT film can be collected by breaking up this brittle membrane. The conductivity of this SWCNT film can advantageously be higher than 280 S/cm. An electroactive polymer (EAP) actuator layered with the SWNT-FE shows a higher electric field-induced strain than an EAP layered with metal electrodes because the flexible SWNT-FE relieves the restraint of the displacement of the polymeric active layer as compared to the metal electrode. In addition, if thin enough, the SWNT-FE is transparent in the visible light range, thus making it suitable for use in actuators used in optical devices.

  • Publication number: 20110003212
    Abstract: A multilayer whole solid-type lithium ion rechargeable battery has hitherto been produced by stacking green sheets of a positive electrode layer, a solid electrolyte layer, and a negative electrode layer, which are formed of respective materials different from each other in coefficient of thermal expansion, and firing the layers at a time. This technique poses problems of delamination and nonlamination attributable to a difference in shrinkage. The problems can be solved by forming green sheets with the addition of a sintering aid to each starting material powder for the positive electrode layer, the solid electrolyte layer, and the negative electrode layer and performing control, by setting the additive rate of the sintering aid and the firing temperature, so that the shrinkages of the respective green sheets are substantially equal to each other. Consequently, unfavorable phenomena such as delamination can be prevented.
