New All-Solid Sulphur-Based Battery Outperforms Lithium-ion Technology
Scientists at the Department of Energy’s Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulphur battery with approximately four times the energy density of conventional lithium-ion technologies that power today’s electronics.
The ORNL battery design, which uses abundant low-cost elemental sulphur, also addresses flammability concerns experienced by other chemistries.
“Our approach is a complete change from the current battery concept of two electrodes joined by a liquid electrolyte, which has been used over the last 150 to 200 years,” said Chengdu Liang, lead author on the ORNL study published this week in Angewandte Chemie International Edition.
