Lithium-sulfur batteries are high on the wish-list for future batteries as they are made from cheaper and more environmentally friendly materials than lithium-ion batteries. They also have higher energy storage capacity and work well at much lower temperatures. However, they suffer from short lifetimes and energy loss, writes Uppsala University in a press release<\/a>.<\/p>\n\n\n\n

An article just published in the journal Chem by a research group from Uppsala University has now identified the processes that are limiting the performance of the sulfur electrodes that in turn reduces the current that can be delivered. Various different materials are formed during the discharge\/charge cycles and these cause various problems. Often a localized shortage of lithium causes a bottleneck.<\/p>\n\n\n\n

\u201cLearning about problems allows us to develop new strategies and materials to improve battery performance. Identifying the real bottlenecks is needed to take the next steps. This is big research challenge in a system as complex as lithium-sulfur,\u201d says Daniel Brandell, Professor of Materials Chemistry at Uppsala University who works at the \u00c5ngstr\u00f6m Advanced Battery Centre.<\/p>\n\n\n\n

Combined various techniques<\/h3>\n\n\n\n

The study combined various radiation scattering techniques: X-ray analyses were made in Uppsala, Sweden and neutron results came from a large research facility, the Institut Laue Langevin, in Grenoble, France.<\/p>\n\n\n\n

\u201cThe study demonstrates the importance of using these infrastructures to tackle problems in materials science,\u201d says Professor Adrian Rennie. \u201cThese instruments are expensive but are necessary to understand such complex systems as these batteries. Many different reactions happen at the same time and materials are formed and can disappear quickly during operation.\u201d<\/p>\n\n\n\n

The study was carried-out as part of a co-operation with Scania CV AB.<\/p>\n\n\n\n

\u201cElectric power is needed for the heavy truck business and not just personal vehicles. They must keep up with developments of a range of different batteries that may soon become highly relevant,\u201d says Daniel Brandell.<\/p>\n\n\n
