Ⅱ. Purpose of research and development
· Development of key technologies to understand defect chemistry and to control the distribution of defects at an atomic level of nanostructured electrode materials for Li batteries
· Control of morphology in zero- or one-dimensional nanostructured electrodes during crystallization for efficient lithium storage
· Establishment of a new model between atomic-scale control and physical properties of the materials

Ⅲ. Contents and scopes of the research and development
The distribution and local concentration of lattice defects in nanostructured crystals such as dopants and atomic vacancies have been recognized as significant factors that govern the overall electrical and electrochemical properties of inorganic crystals. Furthermore, as the chemically different environment induced by point defects leads to breaking of the ordered arrangement of atoms in crystals with a complex structure, mass and charge transport behaviors are also considerably affected by the presence of the defects. Therefore, the controls of nanostructure formation as well as distribution of crystal defects at an atomic level are recognized as key issues to develop and understand new electrochemical properties of electrodes in Li batteries. In this research project, various manipulations and observations of point defects in solids and nanostructure evolution will be studied, using inorganic nanoparticles, nanotubes and nanowires. In particular, a variety of physical and chemical analysis techniques such as HREM, SPM and EELS will be utilized to comprehend the relationship between atomic-scale defects and overall bulk properties. A study of surface reaction and mass transport control is crucial as well in transition metal oxides which are applicable to lithium storage electrodes in secondary batteries. Finally, based on the experimental observation and theoretical approach, the optimum design of nanostructured electrodes will be able to be suggested for better electrochemical performances.
