6. Microwave Assisted Ultra-Fast Method to Synthesize Carbonate-Phosphates, Na3MCO3PO4 (M = Mn, Fe, Co, Ni) - Relevant Materials Applied in Sodium-Ion Batteries
Although largely used in mobiles and electric vehicles applications, insertion batteries based on Li-ion technology are high-cost devices. These applications require high-performance energy storage systems with high-energy and high-power densities, which are better attained by Li-ion technology. However, stationary applications such as power plants and unint
