Battery life in phones and EVs could last much longer thanks to new type of capacitor that scientists created by mistake. (Image credit: Viaframe/Getty Images) A new material structure could revolutionize energy storage by enabling the capacitors in electric vehicles or devices to store energy for much longer, scientists say.Researchers have developed capacitors from new "heterostructures" with a novel property that reduces the speed at which energy dissipates without affecting their ability to ...
