New glass-ceramics of chalcogenide materials for electrochemical energy storage
A carbon-free renewable energy future requires that next generation electrochemical energy storage systems be developed. Even as successful as the present lithium batteries have been, their dependence on flammable liquid electrolytes require that new battery systems be developed. Safer all-solid-state batteries which would not suffer from leakage, volatilization, or flammability could be an alternative. The development of all-solid-state sodium batteries should not be overlooked either. Sodium is indeed among the most abundant of all elements and significantly cheaper than lithium. The aim of the project is to identify Na+ conducting chalcogenide glass-ceramics with performances in terms of conductivity and electrochemical stability that will allow the development of all-solid-state batteries working at ambient temperature and suitable for nomad application, vehicle propulsion application and domestic use to store the energy arising from intermittent source. We propose to study Na-P-S(e) and Na-As-P-S systems by neutron thermodiffractometry. These measurements will help to identify new metastable phases which could be interesting as solid electrolytes.
