Researchers at TUM and TUMint.Energy Research have taken a significant step towards improving solid-state batteries. They developed a new material made of lithium, antimony and scandium that conducts lithium ions more than 30% faster than any previously known material. The work is published<\/a> in the journal Advanced Energy Materials<\/i>.<\/p>\n

The team led by Prof. Thomas F. F\u00e4ssler from the Chair of Inorganic Chemistry with a Focus on Novel Materials partially replaced lithium in a lithium antimonide compound with the metal scandium. This creates specific gaps, so-called vacancies, in the crystal lattice of the conductor material. These gaps help the lithium ions to move more easily and faster, resulting in a new world record for ion conductivity.<\/p>\n

Since the measured conductivity far exceeded that of existing materials, the team collaborated with the Chair of Technical Electrochemistry under Prof. Hubert Gasteiger at TUM to confirm the result.<\/p>\n

Co-author Tobias Kutsch, who conducted the validation tests, commented, “Because the material also conducts electricity, it presented a special challenge, and we had to adapt our measurement methods accordingly.”<\/p>\n

F\u00e4ssler sees great potential for the new material, adding, “Our result currently represents a significant advance in basic research. By incorporating small amounts of scandium, we have uncovered a new principle that could prove to be a blueprint for other elemental combinations. While many tests are still needed before the material can be used in battery cells, we are optimistic.<\/p>\n

“Materials that conduct both ions and electrons are particularly well-suited as additives in electrodes. Because of the promising practical app<\/a>lications, we’ve already filed a patent for our development.”<\/p>\n

In addition to its faster conductivity, the material also offers thermal stability and can be produced using well-established chemical methods.<\/p>\n

The researchers have even discovered an entirely new class of substances through their work, as first author Jingwen Jiang, scientist at TUMint.Energy Research, emphasizes, “Our combination consists of lithium-antimony, but the same concept can easily be applied to lithium-phosphorus systems.<\/p>\n

“While the previous record holder relied on lithium-sulfur and required five additional elements for optimization, we only need scandium as an additional component. We believe that our discovery could have broader implications for enhancing conductivity in a wide range of other materials.”<\/p>\n
