China-US team uses graphene composite separator to suppress polysulfide shuttling in Li-S batteries

Green Car Congress

In their paper on the work published in the journal Joule , the researchers reported that by using a reduced graphene oxide (rGO)/sodium lignosulfonate (SL) composite on the standard polypropylene (PP) separator (rGO@SL/PP), they demonstrated a highly robust Li-S battery with a capacity retention of 74% over 1,000 cycles. … 2018.07.022.

Fraunhofer develops new dry-coating process for battery electrodes

Green Car Congress

The active material, conductive carbon and binders are dispersed in a solvent to make a paste, which is initially applied to the metal foil to form a wet coating. It could equally be used on lithium-ion cells as on lithium-sulfur or sodium-ion cells. We are even looking at solid-state batteries.

Stellantis Ventures invests in startup Tiamat for sodium-ion battery technology – ET Auto

Baua Electric

Tiamat was one of 11 top-performing technology startups honoured with a Stellantis Ventures Award in 2023, and is the first company in the world to have recently commercialized a sodium-ion technology in an electrified product. Sodium-ion technology offers a lower cost per kilowatt-hour and is free of lithium and cobalt.
