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. h is achieved with an estimated raw active materials cost of $7.02 of peak charge capacity.

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

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

Green Car Congress

It replenishes lithium ions that cathodes lose over extended use and restores their atomic structures back to their original states. The problem is this pressurizing step raises costs and requires extra safety precautions and special equipment, said Chen. —first author Yang Shi, who performed this work as a postdoc in Chen’s lab.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The Stanford study considered a future US grid where up to 80% of the electricity comes from renewables. Click to enlarge. A new study by Charles J.

Blink Charging

With an extended lifespan, they reduce the need for replacements, minimize environmental impacts, and lower ownership costs. Battery technology monitors the battery State of health (SoH), indicating degradation and remaining capacity. Typically, when the SoH reaches 70%, it’s considered the end of battery life. Notably, several U.S.
