Dataset for modelling studies presented in 'Ultra-high discharged energy density capacitor using high aspect ratio Na0.5Bi0.5TiO3 nanofibers'

Data obtained from 2D finite element electrostatic model of a single high permittivity inclusion within a low permittivity matrix. The angle and aspect ratio of the inclusion has been varied and the local electric field in each element recorded and stored in the raw data files. Permittivity is recorded for each structure. A compiled dataset is also included on the study of the effect of an interfacial layer between the high permittivity inclusion and low permittivity matrix on the electric field distribution within the composite. In this case the maximum field concentration within the matrix and the interfacial layer are recorded alongside the permittivity for varying interlayer thickness.

Data collection method:

Ansys APDL was used to create models and output data files are elemental solutions from structures with a single high permittivity inclusion in a low permittivity matrix, with varying aspect ratio and angle with respect to applied field, and a single high permittivity inclusion of varying aspect ratio with an interphase with varying thickness between the inclusion and the matrix. Further details regarding the methodology behind the two models can be found in the paper 'Ultra-high discharged energy density capacitor using high aspect ratio Na0.5Bi0.5TiO3 nanofibers,' Journal of Materials Chemistry A 5 (2017) 7091-7102.

Additional information:

Raw data output from Ansys for different aspect ratios and angles of a single high permittivity inclusion in a low permittivity matrix is contained in .csv files within the Raw Data.zip. Elemental solutions were read from each element formed during meshing of the model. Columns are as follows: 1: Element number 2: Element area 3: Electric field in element (x) 4: Electric field in element (y) 5: Electric field vector sum in element 6: Material number of element (1 = matrix, 4 = high permittivity inclusion (BNT)) Compiled data for the model looking at the effect of an interphase of varying thickness - column headings are given in file. Electric field data are normalised to a magnitude of 1, i.e. the field applied across the model in the x-direction. For example an electric field of 3 in a given element has a local field three times greater than the applied field.
