High Performance Electrodes for All-Solid-State Supercapacitor Prepared by Using E-Jet Deposition Technique

Abstract:

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.
