Power/Performance Bits: March 2 Fast-charging EV battery; DNA origami nanowires; tiling nanosheets. Fast-charging EV battery Electric vehicle adoption faces challenges from consumers’ range anxiety and the extended lengths of time needed to charge a car’s battery. Researchers at Pennsylvania State University are trying to address this by developing lithium iron phosphate EV batteries that have a range of 250 miles with the ability to charge in 10 minutes. It also is expected to have a lifetime 2 million miles. “We developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion engine vehicles,” said Chao-Yang Wang, chair of mechanical engineering, professor of chemical engineering, professor of materials science and engineering, and director of the Electrochemical Engine Center at Penn State. “There is no more range anxiety and this battery is affordable.”
