Innovative Supercapacitors

Supercapacitors are becoming one of the most important electrochemical

storage devoces. The IES project aim to develop innovatice

supercapacitors having high energy and containing new and safe

components, able to work in a broad range of temperatures.

Project status Project completedProject completed
Project duration July 2012 until December 2015

Supercapacitors display high power and extraordinary cycle life and they are currently used for an increasing number of applications. However, in order to further increase the applications of supercapacitors an increase of their energy appears necessary. Moreover, the development of safe and environmentally friendly supercapacitors is also required. IES project aim to develop innovatice supercapacitors having high energy and containing new and safe components. In this phase the materials (active and electroyte) will be used on the final IES prototype are under development. At month 18 all material will be selected, and the realization of the IES prototype will start. The testing of the prototype will be completed for the end of the project.

Supercapacitors market

The energy of the currently available supercapacitor is the order of 5 Wh/kg. This energy is enough to fulfill the need of present applications. However, in order to enlarge the number of applications (and consequently the market) of supercapacitor, higher energy is needed.The goal of IES project is to realize innovative supercapacitors displaying energy higher than 10 Wh/kg, high power and cycle life comparable with those of theavailabale devices. Such innovatice supercapcitors will be realized using ionic liquids-based electrolytes, carbonaceous materials with high affinity for these electrolytes and environmentally friendly inactive components.
