The surface region of commercial stainless steel 304 and 316 plates has been modified through deposition of the multi-layered coatings composed of titanium film (0.1 ㎛) and gold film (1-2 ㎛) by an electron beam evaporation method. XRD patterns of

LiNi0.8Co0.2O2 is a promising candidate to replace LiCoO2. The present paper describes the preparation of LiNi0.8Co0.2O2 compounds from nitrate sources and sucrose (or sugar) by the sucrose combustion process (SCP), which involves application of a co

In the present work, we studied the role of nanoparticles in ferroelectric/silver composites, in which silver is the secondary particle. The ferroelectric system that we adapted was PNN-PZT. To make the PNN-PZT/silver nanocomposite, we hot-pressed th

Substituting Cd2+ ions into the A and B sites in a Pb(Ni1/3Nb2/3)O3PbZrO3PbTiO3 (PNNPZPT) ternary perovskite material made it possible to determine the effects of the Cd2+ ion substitution site on sintering behavior. The substitution site of the Cd2+

With variations in compositions in layered Li[Ni,Co,Mn]O 2 , we could change the several factors that might be considered to influence the electrochemical properties. The crystallographic characteristics of the samples were studied by neutron diffrac

LiFePO4/C composite is one of ways to surmount the lower electrical conductivity of LiFePO4. In this paper, we suggest a new type of LiFePO4/C composite in which amorphous nano-carbon webs are wrapping and connecting LiFePO4 particles. This type of c

Olivine-type, orthorhombic, LiFePO4 powders with small particle size have been successfully synthesized by the emulsion-drying method. The electronic and crystal structure is analyzed by X-ray absorption spectroscopy (XAS) and X-ray diffraction Rietv
