| Research Abstract |
Nanoparticle dry deposition has been investigated based on relatively-soft surface activation, using NiO-YSZ composite nanoparticle as a model material. As a result, the porous film consisting of NiO-YSZ composite nanoparticle has been successfully obtained when the size of nanoparticles was less than about 10nm. It has been considered that the observed nano-joining at room temperature may be caused by a mechanochemical reaction which facilitates the dehydration-condensation between the couples of surface hydroxyl groups on two dissimilar particles. A low polarization loss was demonstrated for the SOFC anode fabricated by the present deposition process and subsequent sintering. In addition, a dry processing method for cathodes of Li-ion battery has been investigated. It was demonstrated that the core/shell type composite nanoparticles can be frictionally charged enough for electro static deposition.
