PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

The LiRAP solid electrolytes conduct Li + ions well at high voltage and high current, providing much enhanced energy density and power capacity as well as safety. PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery. Lithium sulfur.

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.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. An example, she says, is the task of balancing energy flows in the power grid.

Argonne researchers advancing new class of selenium sulfide composite cathodes that could boost Li-ion energy density 5x

Green Car Congress

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. Recently, lithium?sulfur Click to enlarge.

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

Green Car Congress

Li-S batteries hold significant promise due to their high theoretical specific energy of 2,567 Wh kg −1 , assuming the complete electrochemical reduction of α-sulfur to S 2− (i.e., without the formation of lithium polysulfide). c) Elemental mapping of the carbon-sulfur composite by EDS color pixel-mapping.
