Held as a virtual ceremony for the first time this year, the award jury singled out a plug-and-play solution for second-life EV batteries, a cost-optimized battery for commercial vehicles, and an innovative battery that is built from abundant materials and literally runs on thin air, as worthy of a spot on the big stage. pv magazine takes a closer look at the 2020 ees Award winners.
