Descripción del proyecto
Baterías recargables innovadoras a base de calcio
Actualmente, menos del 1 % de los automóviles funcionan con baterías. Sin embargo, a pesar de la notable reducción del 50 % en el coste de la tecnología dominante de baterías de ion-litio durante la última década, estas se acercan gradualmente a sus límites fundamentales en términos de densidad energética. Además, existe un riesgo potencial para el suministro de litio. Las baterías basadas en calcio (Ca) resultan prometedoras y especialmente atractivas, ya que el Ca es el quinto elemento más abundante en la corteza terrestre y puede utilizarse como ánodo metálico en electrolitos de amplio potencial a base de disolventes orgánicos. El equipo del proyecto CARBAT, financiado con fondos europeos, tiene como objetivo lograr la prueba de concepto para una batería recargable de ánodo de Ca mediante la sinergia de esfuerzos científicos y conocimientos especializados en cribado computacional, química de coordinación y estado sólido, ciencia de los materiales, electroquímica e ingeniería de baterías.
Objetivo
"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."
