Flexible Printed Supercapacitors Made of Carbon Nanomaterials
State Scholarships Foundation (IKY)
The present investigation concerns the development of a simple injection technology for the manufacture of high performance supercapacitors using inks with nanoparticles of different dimensions on PET and glass. The ink consisted on oxide nanoparticles, CNTs nanotubes and graphene. Graphene contributes to many charge-discharge cycles. The nanoparticles and nanotubes is expected to create conductive electrical pathways that promote load transfer as well as keep the graphene structure stable. The combination of ECDL materials and pseudo capacitive nanomaterials is expected to improve the electrochemical performance of the electrodes.
Different capacitor designs will be explored to enhance capacitance. When designing supercapacitors for multifunctional applications, the flexibility of the devices is also an important aspect. Therefore, the bending and stretching of the condenser must not have any detrimental effect on the structural integrity of the device.The aim is for the capacity to be higher than 100 mF / cm2 and with good cycle stability, greater than 6000 cycles
