A research team from South Korean research university KAIST has developed stable, high-rate lithium-sulfur batteries (LSBs) by using hierarchically porous titanium nitride (h-TiN) as a sulfur host. In a paper in the journal Advanced Materials, the researchers report that h-TiN/S shows a reversible capacity of 557 mAh g-1 even after 1,000 cycles at 5 C rate with only… Read more »
French aerospace technology company Safran has acquired an equity interest in OXIS Energy, a manufacturer of lithium-sulfur (Li-S) cell technology for battery systems. Safran is participating in a £7-million round of fresh funding alongside Aerotec and new investors, including French materials company Arkema. The investments made by these companies, which include Samsung in a previous… Read more »
Lithium-sulfur is seen as one of the most promising chemistries for the next generation of batteries, and the UK battery firm OXIS Energy has been developing the technology for some time. Now OXIS has announced that it will be one of 13 European partners in the Lithium Sulfur for Safe Road Electrification (LISA) project, which… Read more »
Battery developer OXIS Energy has created a 425 Wh/kg, 16 Ah lithium sulfur (Li-S) cell for High Altitude Pseudo Satellites (HAPS), and is working towards a 450 Wh/kg cell design at the end of this year. The company has its sights set on 500 Wh/kg by the end of 2019. “At 425 Wh/kg, OXIS has… Read more »
Researchers at The University of Texas at Dallas have used two-dimensional molybdenum disulfide (MoS2) as a protective layer for Li-metal anodes to greatly improve the performance of Li-S batteries. In “2D MoS2 as an efficient protective layer for lithium metal anodes in high-performance Li–S batteries,” published in Nature Nanotechnology , the researchers report that such a use of MoS2 results in… Read more »
UK battery technology company OXIS Energy will receive a £3.7-million investment from the Brazilian private equity fund Aerotec, paving the way for OXIS to open a subsidiary in Brazil. The agreement provides for a Brazilian team to be trained at OXIS Energy’s headquarters in Oxford, as well as the creation of an R&D center in… Read more »
Researchers at the Paul Scherrer Institute (PSI) in Switzerland and the Université Grenoble Alpes in France have developed a simple method that they say can improve the performance of lithium-sulfur batteries by 25-30%. In “Direct observation of lithium polysulfides in lithium-sulfur batteries using operando X-ray diffraction,” published in Nature Energy, Joanna Conder and colleagues reported… Read more »
Researchers at French battery-maker Saft and Université Paris Est have, for the first time, used a nanocomposite metal hydride as the anode in a complete solid-state battery with a sulfur cathode and LiBH4 electrolyte. In “An all-solid-state metal hydride-Sulfur lithium-ion battery,” published in the Journal of Power Sources, Pedro López-Aranguren and colleagues explain that their… Read more »
New types of electrodes – positive and negative terminals – are considered essential for the development of a new generation of high energy-density batteries. As lithium-ion batteries begin to reach their capacity limits, many researchers are looking at lithium-sulfur as a solution. Sulfur is both lightweight and abundant, with a high theoretical energy capacity. However,… Read more »
The DOE is issuing a funding opportunity (DE-FOA-0001629) for the Vehicle Technologies Office (VTO) of up to $19.7 million to support research and development of advanced vehicle technologies. The funding opportunity seeks projects in four areas, including Battery500 Seedling Projects. The VTO Battery500 Consortium has set a goal of doubling the specific energy of lithium… Read more »
