儲電及熱電材料能源效能探討

In this proposal we focus on investigate the interplay between lattice and electric parameters in the new energy materials. The physical properties will be studied by magnetization, magnetic susceptibility, resistivity, specific heat, x-ray diffraction, inelastic neutron scattering, neutron diffraction measurements. Special attention will be focus on the interplay between the electron-lattice scattering and electron redox capability. Topics proposed to be studied include (1) non-s-wave superconducting pairing that may appear in the nano-sized superconducting elements having sizes near the Anderson regime; (2) nano-sized Prussian Blue Analogue (PBA): development of Li+-PBA and Na+-PBA secondary battery and enhancing the electric cycleability by the proximity of magnetic Ni and metalic Sn/In nanoparticles by PBA nanoparticles; (3) thermoelectric materials (Ge0.86Sb0.14-xBix)Te, by measuring the phonon dispersions in the low temperature Fm-3m and high temperature Cmmm phases to extract phonon lifetime, paragation length for the origion of low thermal conductivity.
