Fraunhofer IWS in Dresden, Germany will hold its 3rd annual workshop on Lithium-sulfur batteries from 12-13 November 2014. As with the prior Lithium-Sulfur Battery Workshops in 2012 and 2013, this year’s symposium will bring together an international audience of scientists and industrial customers.
nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In this work we explore the sodium and lithium conversion of ultrafine FeS 2 nanoparticles, with a tight size distribution centered around ∼4.5 —Anna Douglas.
PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery. Lithiumsulfur. The first PATHION presentation described the role of LiRAP in a solid-state lithium-sulfur electrolyte.
Researchers at Stanford University and SLAC led by Stanford associate professor Yi Cui have used a sulfur–TiO 2 yolk–shell design for a cathode material for a lithium-sulfur battery that achieved an initial specific capacity of 1,030?mAh?g Click to enlarge. C and Coulombic efficiency of 98.4% over 1,000 cycles. Click to enlarge.
In their paper on the work published in the journal Joule , the researchers reported that by using a reduced graphene oxide (rGO)/sodium lignosulfonate (SL) composite on the standard polypropylene (PP) separator (rGO@SL/PP), they demonstrated a highly robust Li-S battery with a capacity retention of 74% over 1,000 cycles. … 2018.07.022.
It could equally be used on lithium-ion cells as on lithium-sulfur or sodium-ion cells. This project demonstrated that it is possible to manufacture electrodes continuously, regardless of the type of battery. The range of possible uses for the technology is not limited to a particular cell chemistry.
As described in an open-access paper in the RSC journal Chemical Communications ,the polymer exhibits high sulfur content and offers longer lifetime stability compared to pure sulfur, providing new protocols to develop new cathode materials for Li-S batteries. Cycling performance of Az-S and pure sulfur at 0.3 Chen et al.
Next generation sodium ion batteries–NEXGENNA. It will accelerate the development of sodium ion battery technology by taking a multi-disciplinary approach incorporating fundamental chemistry right through to considerations for scale-up and cell manufacturing.
Recently, lithium?sulfur sulfur (Li/S) and lithium?oxygen Selenium has higher electrical conductivity compared to sulfur and high theoretical gravimetric capacity (678 mA·h g -1 ) and volumetric capacity (3,268 mA·h/cm 3 ). oxygen (Li/O 2 ) cells have been demonstrated to possess the potential to provide 2?5 Batteries'
sulfur phase within carbon nanofibers that enables successful operation of Lithium-Sulfur (Li-S) batteries in carbonate electrolyte for 4000 cycles. 2022) “Stabilization of gamma sulfur at room temperature to enable the use of carbonate electrolyte in Li-S batteries.” Commun Chem 5, 17 doi: 10.1038/s42004-022-00626-2.
The team then used ultrasonic irradiation to facilitate the reaction between dilute hydrochloric acid (HCl) solution and an aqueous sulfur precursor of sodium thiosulfate (Na 2 S 2 O 3 ) in the presence of CCs to yield a composite of CC particles with pure nano-size sulfur (CCs/S composite) and a water soluble by-product of sodium chloride (NaCl).
Focus was placed on how best to strengthen the UK’s position in electrochemical energy storage research and make UK industry more competitive, building on the foundations of the three years of investigation already performed.
Stellantis Ventures has made a strategic investment in France-based sodium-ion battery developer Tiamat. Tiamat says its sodium-ion technology is lithium- and cobalt-free and cheaper per kilowatt hour (kWh) when compared with lithium-ion batteries.
Tiamat was one of 11 top-performing technology startups honoured with a Stellantis Ventures Award in 2023, and is the first company in the world to have recently commercialized a sodium-ion technology in an electrified product. Sodium-ion technology offers a lower cost per kilowatt-hour and is free of lithium and cobalt.
Stellantis Ventures, the corporate venture fund of Stellantis, today announced its participation as a strategic investor in Tiamat, a France-based company that is developing and commercializing sodium-ion battery technology. Sodium-ion technology offers a lower cost per kilowatt-hour and is free of lithium and cobalt.
Another chemistry that is coming onstream is sodium ion. CATL, the world’s biggest battery manufacturer and BYD have both indicated they will have Sodium-ion (Na-ion) packs ready for cars this year (2023). Lithium-sulfur batteries have a theoretical energy density that is more than double that of current lithium-ion batteries.
Meanwhile, the US Department of Energy and many automakers are developing cobalt-free batteries , and companies are investing enormous resources in the development of new battery technologies, including the use of glass , lithium metal , lithium-sulfur , sodium , graphene , and zinc air.
Then there are the new battery chemistries that are not lithium based—for instance, sodium-ion and graphene-based batteries. And there have been advances in grid-scale batteries involving liquid metal technology , and improved traditional flow-battery technology using lithiumsulfur.
Stellantis adds another institution to its list of next-generation energy storage partners searching for the sustainable EV battery of the future. The post Stellantis Seeks New EV Battery, Free From Sketchy Materials appeared first on CleanTechnica.
Solid-state, lithium-sulfur, sodium batteries—would all of these still be using graphite in the anode? There’s also pre-lithiation of the anode which is kind of preloading it with lithium ions. Sodium batteries, for example, may have great cold-weather performance. Charged : What about future battery technologies?
Meanwhile, the US Department of Energy and many automakers are developing cobalt-free batteries , and companies are investing enormous resources in the development of new battery technologies, including the use of glass , lithium metal , lithium-sulfur , sodium , graphene , and zinc air.
One possible solution is to move away from lithium-ion batteries and nickel-metal hydrides batteries to other battery chemistries such as. Tesla is moving towards the use of lithium-iron phosphate batteries, as is Ford for some of its vehicles.
