Novel Energy-Oriented Materials (ICN2)

In the neo-energy research group of the Catalonia Institute of nanoscience and nanotechnology  (ICN2) we bring together expertise in Materials Science, Nanomaterials, Electrochemistry and Polymer Chemistry and put it to work for energy-related applications. We actively work on various research projects on energy storage and conversion, an increasingly strategic area which urgently needs fundamental improvements. We design and synthesize new materials, including hybrid nanocomposites, with a strong emphasis on structural control at the microscale and the meso-nanoscale. This work forms the basis for the development of complex, polymaterial architectures conceived and optimized for use in rechargeable lithium batteries, supercapacitors and hybrid energy storage devices.

In addition we are developing two emerging lines on Nanofluids. The first one deals with their design and application as Heat Transfer Fluids and the second represents the first-time development of Electroactive Nanofluids for the fabrication of high energy-density
