The spinel lithium titanate oxide (Li4Ti5O12, LTO) has been extensively studied as one of the most promising alternatives to carbon materials in energy conversion and storage devices, due to its high structural and thermal stability, rate capability, and excellent cycling stability. In this study, Li4Ti5O12/multi-walled carbon nanotubes (LTO-MWCNTs) free-standing and flexible composite electrodes/buckypapers were prepared via tape casting technique and well compared with commercially available LTO. The structural, morphological, electrical and electrochemical properties of LTO-MWCNTs buckypaper as well as LTO were studied. The electrical conductivity of LTO-based buckypaper was found to be very high i. e, 4.4×102 Scm−1 at room temperature. Further, the buckypaper prepared by synthesized LTO showed higher specific capacity (166 mAhg−1) compared to commercially available LTO (137 mAhg−1) at 0.2 C rate. The enhanced electrochemical performance of as-synthesized LTO-based buckypaper is mainly attributed to the higher electronic conductivity and homogeneous distribution of particles with its small size which facilitates large amount of active sites for lithium insertion and also short diffusion paths.

<P>Fe<SUB>3</SUB>O<SUB>4</SUB> multi-granule nanocluster-multiwall carbon nanotube composites for microwave absorbing applications are fabricated by the surface-engineered tape-casting method. The multi-granule nanoclusters are synthesized by a modified polyol hydrothermal method and characterized by transmission electron microscopy, X-ray diffraction and vibrating sample magnetometer. The complex permittivity and permeability of the composites with different granule size of nanoclusters are characterized in X-band range with the reflection method. The absorption peak of the composites are shifted from 11.1<TEX>$ \,$</TEX>GHz to 11.51<TEX>$ \,$</TEX>GHz as granule size increased from 18<TEX>$ \,$</TEX>nm to 35<TEX>$ \,$</TEX>nm.</P>
