Descrizione del progetto
Batterie ricaricabili innovative a base di calcio
Attualmente meno dell’1% delle automobili esistenti al mondo viene alimentata a batterie. Tuttavia, nonostante l’impressionante dimezzamento del costo associato alla tecnologia dominante basata sulle batterie agli ioni di litio (LIB) verificatosi negli ultimi dieci anni, tali dispositivi si stanno gradualmente avvicinando ai loro limiti fondamentali in termini di densità energetica. Inoltre, l’approvvigionamento di litio è intrinsecamente associato a un potenziale rischio. Le batterie basate sul calcio (Ca) sono promettenti e particolarmente interessanti poiché quest’ultimo, oltre a essere il quinto elemento più abbondante nella crosta terrestre, può essere utilizzato come anodo metallico in elettroliti a base di solventi organici ad ampia finestra di potenziale. Il progetto CARBAT, finanziato dall’UE, mira a realizzare una prova di concetto per una batteria ricaricabile con anodo in calcio fondendo gli sforzi scientifici e le competenze in materia di screening computazionale, chimica dello stato solido e di coordinazione, scienza dei materiali, elettrochimica e ingegneria delle batterie.
Obiettivo
"We propose calcium based rechargeable batteries to be a FET helping to solve some of the Grand Challenges our modern society is facing: pollution, oil-dependency, and climate change. Today transportation contributes to >25% of the total CO2-emissions globally and while electrification of the sector is on-going still <1% of cars run on batteries – mainly due to issues of cost and driving ranges feasible (energy density limited). While the cost of the totally dominant Li-ion battery (LIB) technology has been reduced by an impressive 50%(!) the last decade, LIBs are slowly reaching their fundamental limits in terms of energy density. Furthermore, the risk of limited lithium supply and associated cost increases cannot be ignored. Therefore, new sustainable battery chemistries must be developed and Next Generation Batteries was indeed ranked as the #2 game-changing technology by the World Economic Forum in Davos 2016.
Batteries based on Ca have promise of leap-frog increase in energy densities and are especially attractive as Ca is the 5th most abundant element on Earth’s crust and can be used as metallic anode in conventional wide potential window electrolytes, as recently showcased by the coordinating partner. The main objective of CARBAT builds on this breakthrough and is to achieve proof-of-concept for a Ca anode rechargeable battery with > 650 Wh/kg and > 1400 Wh/l. CARBAT will accomplish this by combining scientific efforts and excellence in computational screening, solid-state and coordination chemistry, materials science, electrochemistry, and battery engineering, and apply this to: (i) develop cathode active materials operating at 4 V and with capacities of 200-300 mAh/g (ii) optimize electrolyte formulations for fast Ca2+ transport (>1 mS/cm), and finally (iii) assembly of 100 mAh full cell demonstrators integrating such materials which will be validated and benchmarked vs. the state-of-the-art Li-ion technology using performance and sustainability indicators."
