Holistic cell design leads to high-performance, long cycle-life Li/S battery

Researchers have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.

Nov. 19, 2013 — Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.A schematic of a lithium-sulfur battery with SEM photo of silicon-graphene oxide material.Demand for high-performance batteries for electric and hybrid electric vehicles capable of matching the range and power of the combustion engine encourages scientists to develop new battery chemistries that could deliver more power and energy than lithium-ion batteries, currently the best performing battery chemistry in the marketplace.For electric vehicles to have a 300-mile range, the battery should provide a cell-level specific energy of 350 to 400 Watt-hours/kilogram (Wh/kg). This would require almost double the specific energy (about 200 Wh/kg) of current lithium-ion batteries. The batteries would also need to have at least 1,000, and preferably 1,500 charge-discharge cycles without showing a noticeable power or energy storage capacity loss.”Our cells may provide a substantial opportunity for the development of zero-emission vehicles with a driving range similar to that of gasoline vehicles,” says Elton Cairns, of the Environmental Energy Technologies Division (EETD) at Berkeley Lab.The battery initially showed an estimated cell-specific energy of more than 500 Wh/kg and it maintained it at >300 Wh/kg after 1,000 cycles — much higher than that of currently available lithium-ion cells.The team is now seeking support for the continuing development of the Li/S cell, including higher sulfur utilization, operation under extreme conditions, and scale-up. Partnerships with industry are being sought. The next steps in the development are to further increase the cell energy density, improve cell performance under extreme conditions, and scale up to larger cells.The results were reported in the journal Nano Letters, in a paper authored by Min-Kyu Song (Molecular Foundry, Berkeley Lab), Yuegang Zhang (Suzhou Institute of Nano-Tech and Nano-Bionics, Chinese Academy of Sciences) and Cairns (Environmental Energy Technologies Division, Berkeley Lab). The research was funded by the U.S. Department of Energy’s Office of Science and a University of California Proof of Concept Award.

The work was not planned and the risks ignored.”Forklift trucks remain one of the most dangerous hazards in the construction industry and executives must ensure they plan any work involving the vehicle properly.By Chris StevensonOr call us on freephone 0800 884 0321SHARE THIS

Global carbon emissions set to reach record 36 billion tons in 2013

Global emissions of carbon dioxide from burning fossil fuels are set to rise again in 2013, reaching a record high of 36 billion tons – according to new figures from the Global Carbon Project. The biggest contributors to fossil fuel emissions in 2012 were China (27 per cent), the United States (14 per cent), the European Union (10 per cent), and India (6 per cent). The projected rise for 2013 comes after a similar rise of 2.2 per cent in 2012.

via ScienceDaily: Top Science News:

Nov. 18, 2013 — Global emissions of carbon dioxide from burning fossil fuels are set to rise again in 2013, reaching a record high of 36 billion tonnes – according to new figures from the Global Carbon Project, co-led by researchers from the Tyndall Centre for Climate Change Research at the University of East Anglia (UEA).The 2.1 per cent rise projected for 2013 means global emissions from burning fossil fuel are 61 per cent above 1990 levels, the baseline year for the Kyoto Protocol.Prof Corinne Le Quéré of the Tyndall Centre for Climate Change Research at the University of East Anglia led the Global Carbon Budget report. She said: “Governments meeting in Warsaw this week need to agree on how to reverse this trend. Emissions must fall substantially and rapidly if we are to limit global climate change to below two degrees. Additional emissions every year cause further warming and climate change.”Alongside the latest Carbon Budget is the launch of the Carbon Atlas – a new online platform showing the world’s biggest carbon emitters more clearly than ever before. The Carbon Atlas reveals the biggest carbon emitters of 2012, what is driving the growth in China’s emissions, and where the UK is outsourcing its emissions. Users can also compare EU emissions and see which countries are providing the largest environmental services to the rest of the world by removing carbon from the atmosphere.“We are communicating new science,” said Prof Le Quéré. “Everyone can explore their own emissions, and compare them with their neighbouring countries – past, present, and future.”The Global Carbon Budget reveals that the biggest contributors to fossil fuel emissions in 2012 were China (27 per cent), the United States (14 per cent), the European Union (10 per cent), and India (6 per cent). The projected rise for 2013 comes after a similar rise of 2.2 per cent in 2012.The rise in fossil fuel emissions in 2012 and 2013 was slower compared to the average 2.7 per cent of the past 10 years. Growth rates in CO2 for major emitting countries in 2012 were China (5.9 per cent) and India (7.7 per cent). …

Ancient, modern DNA tell story of first humans in the Americas

An anthropology professor has looked to DNA to tell the story of how ancient humans first came to the Americas and what happened to them once they were here.

via ScienceDaily: Top Science News:

Nov. 18, 2013 — University of Illinois anthropology professor Ripan Malhi looks to DNA to tell the story of how ancient humans first came to the Americas and what happened to them once they were here.He will share some of his findings at the meeting, “Ancient DNA: The First Three Decades,” at The Royal Society in London on Nov. 18 and 19.Malhi, an affiliate of the Institute for Genomic Biology at Illinois, will describe his collaborative approach, which includes working with present-day Native Americans on studies of their genetic history.He and a group of collaborators from the Tsimshian Nation on the northwest coast of British Columbia, for example, recently found a direct ancestral link between ancient human remains in the Prince Rupert Island area and the native peoples living in the region today. That study looked at changes in the mitochondrial genome, which children inherit only from their mothers.Other studies from Malhi’s lab analyze changes in the Y chromosome or the protein-coding regions of the genome.”The best opportunity to infer the evolutionary history of Native Americans and to assess the effects of European colonization is to analyze genomes of ancient Native Americans and those of their living descendants,” Malhi said.”I think what makes my lab unique is that we focus not only on the initial peopling of the Americas but also what happened after the initial peopling. How did these groups move to new environments and adapt to their local settings over 15,000 years?”While continuing his work in British Columbia, Malhi also is setting up study sites in California, Guatemala, Mexico and Illinois.”What’s interesting about the northwest coast and California is that these communities were complex hunter-gatherer societies, whereas in Mexico and Guatemala, it’s more communities that transitioned to farming and then experienced the effects of European colonization,” he said.Genomic studies can fill in the blanks on studies that seek to tell the story of life in the Americas before and after European colonization, Malhi said. Researchers may draw the wrong conclusions about human history when looking only at artifacts and language, he said.
