Ilika and Johnson Matthey partner to develop protected anodes for Li-S batteries

International materials company Ilika, a developer of solid-state batteries, is taking part in a three-year project, led by Johnson Matthey, to develop protected anodes for lithium-sulfur batteries. The project will take advantage of Ilika’s high-throughput materials development technique to discover new electrolyte composition options and fabricate a free-standing, lithium-containing protected anode/separator for integration into pouch… Read more »

New study identifies one culprit behind Li-sulfur battery capacity fade

Lithium-sulfur batteries theoretically offer high energy density, and are widely seen as a promising next-generation energy storage system. However – you guessed it – they have several drawbacks. Among other issues, capacity tends to fade quickly. Researchers at the DOE’s Pacific Northwest National Laboratory (PNNL) have identified one of the reasons behind this problem, and found… Read more »

Sony working on high-capacity lithium-sulfur and magnesium-sulfur batteries

Sony, the company that introduced the world’s first commercial lithium-ion battery in 1991, is already well along the road to a Li-ion replacement, according to Nikkei Technology. The company is reportedly developing high-capacity lithium-sulfur and magnesium-sulfur batteries, aiming for a 40% increase in volumetric capacity to 1,000 Wh/l, and plans to commercialize the new chemistries… Read more »

European researchers: Our new Li-sulfur battery is more energy-dense, cheaper and safer

EU-funded researchers in the LISSEN (Lithium Sulfur Superbattery Exploiting Nanotechnology) project have developed a new lithium-sulfur battery that uses lithiated silicon as the anode and a nanostructured sulfur-carbon composite as the cathode. The team says its battery offers an energy density at least three times higher than that of current lithium battery technology, as well… Read more »

European ALISE collaboration aims to commercialize lithium-sulfur batteries

A coalition of European manufacturers and research institutes has launched ALISE (Advanced Lithium Sulfur battery for EVs), a collaborative effort to develop and commercialize lithium-sulfur technology. The objective of the 7-million-Euro ($7.6 million) project is to achieve a stable 500 Wh/kg Li-S cell by 2019. The final deliverable of the ALISE project will be a… Read more »

Researchers discover new high-performance cathode material for lithium-sulfur batteries

Lithium-sulfur batteries are one of the hottest topics in the battery field today, as they could theoretically offer energy density up to four times higher than that of lithium-ion batteries. However, one of several challenges to be overcome is finding cathode materials that demonstrate long-term stability. An international team of researchers from Drexel University and… Read more »

Researchers announce significant improvement in Li-S battery performance and cycle life

A team from the University of Waterloo in Canada and BASF has developed a way to stabilize cathodes in lithium-sulfur batteries, significantly improving performance and cycle life. Li-S batteries offer high theoretical energy density and low cost, due to the high natural abundance of sulfur. However, the insulating nature of sulfur and lithium sulfides requires… Read more »

Graphene wrapper enhances performance of lithium-sulfur batteries

Lithium-sulfur batteries are of great interest, as they could offer specific energy densities far greater than those of current lithium-ion chemistries. However, current designs are plagued by low efficiency and capacity degradation. A team of researchers from the University of Cambridge and the Beijing Institute of Technology has devised a three-dimensional sandwich-type graphene sheet-sulfur/carbon composite… Read more »

OXIS Energy achieves specific energy of 300 Wh/kg with lithium-sulfur cell

OXIS has developed its largest lithium-sulfur cell to date, achieving specific energy in excess of 300 Wh/kg. The company has also increased cell capacity to 25 Ah, a twelve-fold improvement in 18 months. OXIS predicts that it will achieve a cell capacity of 33 Ah by mid-2015. The OXIS scientific team expects to achieve its… Read more »

Fraunhofer Institute presents November workshop on lithium-sulfur batteries

The Fraunhofer Institute will hold its third annual workshop on lithium-sulfur batteries in Dresden, Germany, on November 12 and 13. Lithium-sulfur is a leading contender for the battery chemistry of the future, and Fraunhofer believes that novel materials such as nanostructured carbon/sulfur composite cathodes, solid electrolytes and alloy-based anodes will significantly enhance performance.
