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.

以NiO-YSZ复合纳米粒子为模型材料，研究了基于相对软表面活化的纳米粒子干法沉积。结果表明，当纳米粒子的粒径小于10 nm时，可以成功地制备出由NiO-YSZ复合纳米粒子组成的多孔薄膜。有人认为，在室温下观察到的纳米连接可能是由机械化学反应，这有利于两个不同的颗粒上的表面羟基之间的脱水-缩合。通过本发明的沉积工艺和随后的烧结制备的SOFC阳极表现出低的极化损耗。此外，还研究了锂离子电池负极的干法处理方法。结果表明，核/壳型复合纳米粒子可以被静电沉积足够的电荷。
