Abstract
The widespread deployment of intermittent renewable energy depends critically on the development of energy storage technologies. Storing renewable energy in rechargeable batteries is one of few viable solutions. For large-scale deployment, however, the storage performance of batteries must be improved and costs reduced. The MePhEES project aims to develop new nanostructured transition metal phosphides (TMPs) and investigate their electrochemical performance for use as anode materials in Lithium-ion/Sodium-ion batteries (LIBs/SIBs). TMPs have high theoretical capacity, high electrical conductivity, and relatively low redox potential versus Li/Li+ or Na/Na+ compared to transition metal sulfides, fluorides, and oxides, and therefore hold substantial promise for improving Li and Na storage performance. The main objectives of this project include: (i) Synthesis of nickel phosphide (Ni-P) and cobalt phosphide (Co-P) nanostructures; (ii) Fabrication of carbon nanotube (CNT)/TMP nanocomposite electrodes; (iii) Investigation of Li/Na storage performance of synthesized TMP nanostructures as well as CNT/TMP nanocomposite electrodes in collaboration with UT-Austin partner. This project will provide invaluable training opportunities for postdoc researchers and PhD students, and also promote the involvement of Portuguese researchers in renewable energy-related projects which are traditionally not a dominant area of research in Portugal. The proposed research falls within the scope of “CoLab Emerging Technologies Research” – “Nanotechnology” and the scientific areas defined in the context of AIR Center – “Clean Energy Tech”.
