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.

Xcel Terms First Phase of Sodium-Sulfur Battery Wind Energy Storage Test Project Successful

Green Car Congress

Xcel Energy has released the preliminary results from its wind-to-battery (W2B) storage project in Minnesota, and termed the technology successful. In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. Molten-salt batteries , as the name implies, use a liquid, molten-salt electrolyte, which freezes at room temperature, allowing the batteries to be stored in an inactive state. He expects the battery to retain over 80% of its charge in that period.

Total Signs Research Agreement with MIT to Develop New Stationary Batteries for Solar Power; Smaller-Scale Version of All-Liquid Metal Battery Work Supported by ARPA-E

Green Car Congress

This agreement valued at $4 million over five years is part of the MIT Energy Initiative (MITEI), which Total joined as a member in November 2008. This new class of batteries could enable continuous power supply from renewable energy sources, such as wind and solar and a more stable, reliable grid. The researchers have since switched.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Aqua Metals works with companies that are really good at collecting, safely transporting, storing, crushing and separating spent lithium-ion batteries. Grid stabilization, solar arrays, wind farms, and even home energy storage systems—some of those are coming offline and already going to their second set of batteries.
