Fraunhofer leading “MaSSiF” research project on solid-state sulfur-silicon batteries

Green Car Congress

The Fraunhofer Institute for Material and Beam Technology IWS in Dresden is leading a research project targeting a new generation of sulfur-based batteries. The combination with sulfur as the cathode active material holds particular promise. However, the anode poses major challenges in the battery's processing and operation.

RPI team develops method to use paper-making by-product in lithium-sulfur batteries

Green Car Congress

Researchers at Rensselaer Polytechnic Institute (RPI) have now developed a method to use this cheap and abundant waste byproduct to build a components for lithium-sulfur batteries. The micropores provide sufficient space to capture substantial amounts of sulfur and accommodate the large volume change of sulfur during cycling.

Silica-based cathode enables long-life Li-S batteries

Green Car Congress

Scientists from the Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel silica-based cathode for lithiumsulfur batteries, thereby enabling the realization of batteries that can last for more than 2,000 charge/discharge cycles. However, using sulfur in batteries is tricky for two reasons.

Drexel team proposes TiO/CNF nanofiber mats to improve Lithium-Sulfur battery performance

Green Car Congress

Researchers in Drexel’s College of Engineering report the ability of stabilized titanium monoxide (TiO) nanoparticles in nanofibers to support high conductivity and to bind polysulfides in Li-S batteries. We have created freestanding porous titanium monoxide nanofiber mat as a cathode host material in lithium-sulfur batteries.

Graphene oxide-sulfur (GO-S) nanocomposite cathodes for high-capacity, stable cycling lithium sulfur batteries

Green Car Congress

A team from Lawrence Berkeley National Laboratory and Tsinghua University (China) have synthesized graphene oxide-sulfur (GO-S) nanocomposite cathodes and applied them in lithium/sulfur cells to show a high reversible capacity of 950-1400 mAh g -1 and stable cycling for more than 50 deep cycles at 0.1C (1C = 1675 mA g -1 ).
