The new, sulfur-based material is more energy-dense, cost-effective, and environmentally friendly than traditional cathodes in lithium batteries.
Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have designed a new, organic cathode material for lithium batteries. With sulfur at its core, the material is more energy-dense, cost-effective, and environmentally friendly than traditional cathode materials in lithium batteries. The research was published in Advanced Energy Materials on April 10, 2019.
Optimizing cathode materials
From smartphones to electric vehicles, the technologies that have become central to everyday life run on lithium batteries. And as the demand for these products continues to rise, scientists are investigating how to optimize cathode materials to improve the overall performance of lithium battery systems.
“Commercialized lithium-ion batteries are used in small electronic devices; however, to accommodate long driving ranges for electric vehicles, their energy density needs to be higher,” said Zulipiya Shadike, a research associate in Brookhaven’s Chemistry Division and the lead author of the research. “We are trying to develop new battery systems with a high energy density and stable performance.”
