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

Green Car Congress

Supported by an ARPA-E grant, LiRAP has proven to be a safe alternative compared to the liquid electrolytes used in most of today’s lithium ion batteries. 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.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. A battery that mitigates these problems is DARPA’s objective.

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

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.
