Electric vehicles can drive longer distances if their lithium-ion batteries deliver more energy in a lighter package. A prime weight-loss candidate is the current collector, a component that often adds 10% to the weight of a battery cell without contributing energy.

While completing his undergraduate studies in the Philippines, atmospheric chemist Christian Salvador caught a glimpse of the horizon. What he saw concerned him: a thin, black line hovering above the city.
![Seeing the difference Ac-225 could make to cancer patients made Raina Setzer want to come to ORNL to directly work with the isotope. Credit: Allison Peacock/ORNL, U.S. Dept. of Energy](/sites/default/files/styles/list_page_thumbnail/public/2023-11/rs_0.jpg?h=71976bb4&itok=nFsgqwUT)
Raina Setzer knows the work she does matters. That’s because she’s already seen it from the other side. Setzer, a radiochemical processing technician in Oak Ridge National Laboratory’s Isotope Processing and Manufacturing Division, joined the lab in June 2023.
![Researchers have shown how an all-solid lithium-based electrolyte material can be used to develop fast charging, long-range batteries for electric vehicles that are also safer than conventional designs.

Currently, the biggest hurdle for electric vehicles, or EVs, is the development of advanced battery technology to extend driving range, safety and reliability.

Carl Dukes’ career as an adept communicator got off to a slow start: He was about 5 years old when he spoke for the first time. “I’ve been making up for lost time ever since,” joked Dukes, a technical professional at the Department of Energy’s Oak Ridge National Laboratory.
![Bob Bolton has spent much of his career studying environmental change in Alaska. He recently moved to East Tennessee to join the ORNL-led NGEE Arctic project as deputy for operations.

Bob Bolton may have moved to a southerly latitude at ORNL, but he is still stewarding scientific exploration in the Arctic, along with a project that helps amplify the voices of Alaskans who reside in a landscape on the front lines of climate change.
