More energy- and cost-efficient batteries will be key to accelerating the adoption of electric vehicles (EVs) and increasing the share of renewable power generation as many countries pledge to make their economies greener in the aftermath of the pandemic. So the race to find the next breakthrough in the most widely used kind of batteries, the lithium-ion battery, is on. Researchers have been at work for years to develop longer-lasting and cheaper batteries that can store more energy. Most recently, scientists at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) have looked at ways to make the battery cathode store more energy at a relatively lower cost. And they think they may have found the solution . The researchers have worked to improve the performance of the lithium-ion battery by using a cathode that is very rich in nickel and working to overcome one key challenge in […]
