Materials and Electrode/Electrolyte Interface Characterization to Develop Aqueous Rechargeable Ammonium Ion Batteries
The advent of ammonium ion batteries is a breath of fresh air in the search for sustainable energy storage devices. The nitrogen and hydrogen gases present in the atmosphere may represent an inexhaustible and clean source of these ions and make future portable and stationary power tremendously cheaper and environmentally benign. The project bets on vanadium phosphates that could produce, in combination with a suitable electrode/electrolyte interface, devices of potential and capacities at least comparable to several aqueous batteries using metal salts in the electrolyte (as, for instance, zinc rechargeable batteries). The development of these phosphates and the optimization of the interfaces may be a key for saying goodbye to our dependence on metal sources with efficient, affordable and clean chemistries.
