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.

纳米粒子的干沉积已根据相对柔软的表面激活进行了研究，使用Nio-ysz复合纳米颗粒作为模型材料。结果，当纳米颗粒的大小小于10nm左右时，已成功获得了由Nio-sz复合纳米颗粒组成的多孔膜。人们认为，在室温下观察到的纳米结合可能是由机械化学反应引起的，该反应促进了两个不同的颗粒上表面羟基夫妻之间的脱水态。通过当前沉积过程和随后的烧结，证明了低极化损失的SOFC阳极。此外，已经研究了一种用于锂离子电池阴极的干加工方法。证明核/壳类型复合纳米颗粒可以在摩擦上充满电，足以用于电静态沉积。
