Considering the great potential of composite electrode with carbon and transition metal oxides as a future ideal form of electrode for future energy storing system, many efforts have been devoted into such aspect of research. Sweet potato-derived carbon framework with nanosheet form of MnO2 anchored on it was carried out through the low-temperature solution grown technique, which is simple, low-cost, and applicable for large-scale commercial production. Such form of composite electrode can facilitate the inner transportation of electrons and ions, and offer high specific capacitance (309 F/g at 0.5 A/g) with comparable discharging rate capability (94 F/g at 20 A/g), which reasonably can be regarded as a superior form of composite electrode.

This paper considers the pure bending problem of simply supported transversely isotropic magneto-electro-elastic circular plates with material coefficients being arbitrary functions of z,the thickness *** expanding the displacement,electric potential and magnetic potential into suitable polynomials in r,the radial coordinate,with the coefficients being the undetermined functions of z,the partial differential equations governing the axisymmetric problems are converted into a set of ordinary differentials,which can be solved by integrating step by step and incorporating with the boundary conditions.A 3D analytical solution for the pure bending problem,which can be degenerated into the homogeneous cases,is thus obtained.A numerical example is present to show the influence of the material inhomogeneity on the elastic,elastic and magnetic fields in the simply supported circular plate of functionally graded magneto-electro-elastic material wtih transverse isotropy.
