Abstract
The electrochemical storage sub-program is a part of a larger program, The Electrical System Research, aimed at developing technical and technological innovation of general interest for the Italian electricity sector. The sub-program is finalized to find new electrochemical energy storage technologies suitable for stationary applications. It intends to study innovative active material with the aim of reducing the preparation costs. To increase the energy density of lithium-ion battery, a combined approach is proposed, which synergistically exploits the properties of salts based on orthoborate anions and ionic liquids. Advanced computational modeling will enable rapid prototyping and screening of materials. At the same time, the replacing of the intercalation materials with materials capable of reacting with lithium by alloying or conversion processes will allow to increase the energy density of the devices. In order to improve the thermal stability and wettability of the separators the use of polymeric non-woven fabrics will be investigated. To foster the development of sodium ion battery study and development of cathode and anode materials that have a high specific capacity, good cyclic stability and high energy density will be carried out. As regards the electrolyte for sodium ion batteries, electrolyte systems based on organic and/or aqueous solvents will be designed. Innovative lithium metal batteries will be also investigated: the key to solving the problem of dendrite formation is reputed be the protection of the lithium anode.
