Lithium-ion batteries from drones might find second lives in less ‘stressful’ devices

Taking flight can be stressful—especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device’s overall lifespan. Research in ACS Energy Letters shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the “stressed out” batteries could also have second lives in less strenuous applications.

Scientists suggest looking beyond hardware to improve solar and other clean energy tech

To continue reducing the costs of solar energy and other clean energy technologies, scientists and engineers will likely need to focus, at least in part, on improving technology features that are not based on hardware, according to MIT researchers. They describe this finding and the mechanisms behind it in Nature Energy.
