ARPA-E awards $175M to 68 novel clean energy OPEN 2021 projects

Green Car Congress

This would eliminate the ionomer, which conducts ions, but also poisons catalyst sites and obstructs oxygen transport. The battery would provide a transportation energy storage solution that could be charged very fast and have a comparable energy density with the state-of-the-art lithium ion. University of Maryland.
