Thermal interface compositions contain both non-electrically conductive micron-sized fillers and electrically conductive nanoparticles blended with a polymer matrix. Such compositions increase the bulk thermal conductivity of the polymer composites as well as decrease thermal interfacial resistances that exist between thermal interface materials and the corresponding mating surfaces. Such compositions are electrically non-conductive. Formulations containing nanoparticles also show less phase separation of micron-sized particles than formulations without nanoparticles.

The invention discloses a preparation method of a layered lithium (Li)-rich manganese (Mn)-based anode material having multiple core-shell structures. The layered (1-t)LiNixCoyMn1-x-yO2@tLi2MnO3 having the multiple core-shell structures is prepared by taking LiNixCoyMn1-x-yO2 (the x is greater than or equal to 0 while the y is less than or equal to 1) as cores and Li2MnO3 with the concentration in gradient change as shells. According to the method, the core-shell structures are applied into the lithium (Li)-rich layered material, namely, the concept of the multiple core-shell structures is put forward, so that the defects reported in the literature that the simple core-shell structure material has poor performance and the concentration gradient material is complicated to operate and difficult to realize are overcome. In the method, the core-shell concentrations are in antigradient change according to a certain arithmetic progression, namely, from the cores to the outer shells, the concentrations of the core materials are in gradually-decreased arithmetic progression distribution while the concentrations of the shell material are in gradually-increased arithmetic progression distribution. During the design, the equal concentration of transition metal ions in every layer is ensured, so that the interfacial resistance of the materials is reduced as far as possible. As a result, the material performance is improved.
