Doorbraak in lithium-zwavel-accu’s brengt gebruik in EV’s dichterbij

AMSTERDAM – Duitse onderzoekers hebben een lithium-zwavel-accu weten te ontwikkelen die een stuk langer meegaat. Voor elektrische auto’s kan dit krachtigere accu’s betekenen.

Een onderzoek pas een lithium-zwafel-accu aanDit melden wetenschappers van het Fraunhofer instituut IWS uit Dresden.

In eerdere tests ging de batterij net 200 oplaadbeurten mee. Door een speciale combinatie van anode en kathode materialen hebben de onderzoekers dit weten te verhogen naar 1400 oplaadbeurten, zo leggen de wetenschappers uit.

 Lithium-zwavel-accu’s kunnen een veel hogere energiedichtheid bereiken dan conventionele lithium-ion-batterijen, verwachten de onderzoekers. “In de praktijk betekent dit dat je twee keer zo ver kan rijden met hetzelfde gewicht aan batterijen”, legt professor Holger Althues uit.

“Dit impliceert natuurlijk dat batterijmodellen veel lichter kunnen. Een interessant gegeven voor autofabrikanten, maar ook voor smartphoneproducenten.” Volgens Althues brengt de uitvinding zelfs elektrische vliegen dichterbij.

    Los Blancos, with captain Sergio Ramos suspended after deliberately collecting a yellow card in the first leg, had been looking to build on a slender 2-1 lead from that game in Amsterdam and stay on course for a potential fourth straight European triumph.

    However, after Raphael Varane’s header rattled the crossbar, Ajax raced into an early lead through Hakim Ziyech before Dusan Tadic set up David Neres for a second in the 18th minute.
    Real Madrid were forced into two changes when Lucas Vazquez and Vinicius Junior went off injured, with substitute Gareth Bale hitting the post just before half-time.

    Ajax looked to have put the tie to bed when Tadic swept in a brilliant third goal just after the hour – which was eventually given following an extensive Video Assistant Referee review to check if the ball had gone out of play in the build-up.

    Ernest Quintana, 78, was at Kaiser Permanente Medical Center in Fremont when a doctor – appearing on the robot’s screen – informed him that he would die within a few days.

    A family friend wrote on social media that it was “not the way to show value and compassion to a patient“.

    The hospital says it “regrets falling short” of the family’s expectations.

    Mr Quintana died the next day.

    Trump was surrounded at Friday’s event by officials from Customs and Border Protection as well as surviving family members of those who have loved ones killed by undocumented immigrants. Attorney General William Barr was also at the President’s veto event.
    While some lawmakers including some Republicans — have argued against the President’s use of national emergency powers in this instance, the Justice Department set forth a robust defense of the President’s authority to do so in a letter to Senate Majority Leader Mitch McConnell earlier this month, according to a copy obtained by CNN on Friday.
    “The President acted well within his discretion in declaring a national emergency concerning the southern border,” wrote Assistant Attorney General Stephen Boyd, setting out the legal basis for the proclamation under the National Emergencies Act and additional statutory authorities, which largely tracks an internal memo issued by the Office of Legal Counsel at the Justice Department.
