Sulfur–TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

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 This is the highest performing sulfur cathode in the world, as far as we know.

Researchers synthesize new Li-S cathode based on “carbon compartments”

Green Car Congress

Researchers from Texas A&M and Purdue have developed a new cathode material for Li-S batteries based on what they call carbon compartments (CCs)—conductive 3D carbon mesostructures that possess macro- and meso-pores that allow for high loading of sulfur nanoparticles and enhanced electrolyte-sulfur contact.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. The scientists found the nanofluids could be used in a system with an energy-storing potential approaching that of a lithium-ion battery and with the pumpable recharging of a flow battery.

carbon composite as cathodes in ether-based electrolyte. New composite materials based on selenium (Se) sulfides used as the cathode in a rechargeable lithium-ion battery could increase Li-ion density five times, according to research carried out at the US Department of Energy’s Advanced Photon Source at Argonne National Laboratory.
