Solid-State Thin-Film Supercapacitors with Ultrafast Charge/Discharge Based on N-Doped-Carbon-Tubes/Au-Nanoparticles-Doped-MnO2 Nanocomposites

The design description and test results of an all solid-state thin-film lithium-ion battery are provided. It is shown that the features of its charge-discharge characteristics are associated with a change in the Fermi level of the electrodes and are caused by a change in the concentration of lithium ions in the course of the charge-discharge. The specific capacitive characteristics of the layout are determined, which are comparable with the characteristics of industrial solid-state lithium-ion batteries.

Charge Discharge

Electrohydrodynamic jet (E-jet) deposition technique was used to prepare thin film porous electrodes for all-solid-state electrochemical supercapacitors. The performance of thin film graphene/PANI electrodes separately prepared by E-jet deposition and brush-coating were comparatively studied in supercapacitors. Results show that the specific capacitance of the supercapacitor by E-jet deposition can reach 228F·g-1 at 0.5A·g-1and remain 92% after 1000 charge-discharge cycles. Compared to those electrodes made by traditional brush coating techniques, the capacitance and cycling stability of the supercapacitors in this work were respectively increased by 11% and 7%, means that E-jet deposition can be an ideal technique for fabrication of high performance supercapacitor electrodes.

Solid-state NMR has proven to be a versatile technique for studying the chemical structure, 3D structure and dynamics of all sorts of chemical compounds. In nanotechnology and particularly in thin films, the study of chemical modification, molecular packing, end chain motion, distance determination and solvent-matrix interactions is essential for controlling the final product properties and applications. Despite its atomic-level research capabilities and recent technical advancements, solid-state NMR is still lacking behind other spectroscopic techniques in the field of thin films due to the underestimation of NMR capabilities, availability, great variety of nuclei and pulse sequences, lack of sensitivity for quadrupole nuclei and time-consuming experiments. This article will comprehensively and critically review the work done by solid-state NMR on different types of thin films and the most advanced NMR strategies, which are beyond conventional, and the hardware design used to overcome the technical issues in thin-film research.
