New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction.

UCSD researchers improve method to recycle and renew used cathodes from Li-ion batteries via eutectic molten salts

Green Car Congress

Illustration of the process to restore lithium ions to degraded NMC cathodes using eutectic molten salts at ambient pressure. The team is tuning this process so that it can be used to recycle any type of cathode materials used in lithium-ion and sodium-ion batteries. The work was published in Advanced Energy Materials.

Lux: Li-ion dominating grid storage market with 90% of 2014 proposals

Green Car Congress

Molten salt batteries still account for a majority of installations by energy capacity, because of NGK Insulators’ early lead, but are no longer the technology of choice, according to Lux. Demand management and renewable connected systems are driving the primary grid storage applications.

Natrium reactor demonstration project slated for Wyoming

Green Car Congress

The Natrium technology has a 345MW sodium fast reactor coupled with a molten salt-based integrated energy storage system that will provide clean, flexible energy and stability for the grid. TerraPower and PacifiCorp announced efforts to advance a Natrium reactor demonstration project at a retiring coal plant in Wyoming.
