2019-03-12 Stensalt-lignende materialer kan potentielt fordoble kapaciteten på Li-batterier
Helt nye materialer med en stensalt-type struktur kan potentielt kan fordoble kapaciteten på Li-batteriers katoder, hvilket kan få stor betydning for mobiltelefoner, bærbare computere og elbiler, der bruger litiumbatterier.
Kom og hør Poul Norby fra DTU Energi fortælle om denne spændende klasse af materialer og deres muligheder på IDA’s arrangement TIRSDAG D. 12. MARTS 2019 KL. 16:45 – 20:30.
Tilmelding kan ske via IDA på https://universe.ida.dk/arrangement/opfoelgning-paa-energilagring-329045/
Litiumbatterier har støt voksende indflydelse på vores hverdag, fra batterier i smartphones og computere over elbiler og køkkenredskaber til storskala opbevaring af overskydende energi fra vindmøller og solceller.
Et højkapacitets elektrodemateriale baseret på vanadium oxyfluorid, Li2VO2F, har for nylig tiltrukket sig stor interesse, da det potentielt kan fordoble kapaciteten af litiumbatteri-katodematerialer og derved have en potentielt stor indvirkning på det moderne batteridrevne samfund. Se f.eks den videnskabelige artikel her https://pubs.rsc.org/-/content/articlepdf/2015/cp/c5cp02505b
Batterier frigiver strøm ved afladning, når positivt ladede ioner bevæger sig inde i batteriet fra anode (-) til katode (+). Det nye materiale kan frigive dobbelt så mange elektroner som eksisterende katodetyper til litiumbatterier, der bruges i elbiler, mobiltelefoner mm.
Jon Fold von Bülow
Jon Fold von Bülow recieved his Cand. Scient. in Nanoscience from University of Copenhagen in 2011 and is currently working with upscaling Li- and Na-ion battery materials to the 100+ kg scale for Haldor Topsøe A/S.
Jon's main interest lies in energy technologies for the future and he started working with fusion energy at Risø National Laboratory for Sustainable Energy. He has since developed a growing interest in technologies that are closer to potential industrial application. He is a highly dedicated academic as well as a very active professional and have initiated and participated in many different projects.
His studies within nanotechnological material science and affiliation with Risø National Laboratories has taken him to Germany, China and the US, where he has collaborated independently with several international research groups. He has so far succeeded in pushing two academic projects to industrial application, first with the Danish company Coloplast A/S and recently with a California-based battery start-up – an invention that is currently being US patented.
Jon has conducted most of his work on Li-batteries in the facilities of California NanoSystems Institute (CNSI) as a research scholar at UCSB-MIT-Caltech Institute for Collaborative Biotechnologies (ICB). The manganese based cathode materials he fabricated during this period were all tuned for high-power applications and covers synthesis of various manganese oxides from solution, molten and solid states.
