Projektet ska bidra till utvecklingen av laddbara aluminiumbatterier som ska kunna användas för storskalig lagring. Vanligt förekommande grundämnen ska användas, den ena elektroden består av aluminium och den andra av organiskt material, vilket kan vara en fördel både ur kostnads- och resurshänseende.
Ärendesammanfattning (eng):
More efficient electrochemical energy storage (EES) options are needed for improved large-scale storage of renewable energy from solar, wind, etc. The omnipresent Li-ion battery technology has severe limitations hindering any large-scale EES implementation why battery researchers must envisage alternative concepts. Here we propose novel Al-batteries for large-scale EES. Al is abundant, cheap, and has many other fundamental promises compared to competing battery concepts. The two main obstacles to overcome are based in the materials needed: i) electrolytes free from Cl- and capable of fast cationic Al3+ transport, and ii) cathodes accommodating the 3 e-/Al3+ – issues here addressed together with an anode designed to allow faster charge/discharge rates. All components needed for a functional Al-battery will be addressed from a basic science point of view, with the following main objectives: Develop an electrolyte Cl- free and with cationic Al3+ complex transport Create Al metal micro-structured anodes to increase surface area and current density, for higher charge/discharge rates Apply organic cathodes originally developed for Mg-batteries for multiple e--transfer Assembly of full Al-batteries and evaluate figures-of-merit for application as EES The project will mainly be performed by 2 postdocs and poses well defined basic science research questions, a very high degree of innovation in the concept, together with a clear future energy area application perspective – large scale EES
