A “novel” manganese and sodium-ion-based material might be a contender for the more universal lithium-ion batteries that power our mobile devices and make us mobile in electric vehicles. Developed by the University of Texas at Dallas in collaboration with Seoul National University, the new material is said to offer “a potentially lower-cost, more ecofriendly option to fuel next-generation devices and electric cars.” Dr. Kyeongjae Cho, professor of materials science and engineering in the Erik Jonsson School of Engineering and Computer Science, thinks battery cost is a “substantial issue.” It may become more of one with electric vehicle production growing from the existing global electric car stock of two million vehicles in 2016 to a projected nine-to-20 million (as reported by the International Energy Agency) by 2020 and between 40 and 70 million by 2025. This rapid growth will put an added burden on finding and extracting lithium, since the mineral exists in relatively small amounts in sometimes isolated places. Correction added …
