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.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

The company is building a new plant in Nevada, and aims to be processing 10,000 tons of black mass (equivalent to about 150,000 EV battery packs) annually by 2025. Aqua Metals works with companies that are really good at collecting, safely transporting, storing, crushing and separating spent lithium-ion batteries.

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

Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS). This analysis indicates that energy storage could provide some grid flexibility but its build up will require decades.

Carnegie Mellon researchers develop semi-liquid lithium metal anode for use with solid electrolytes

Green Car Congress

The method used in this work has great potential for building reliable alkaline metal-based rechargeable batteries. However, researchers have found that the contact between the ceramic electrolyte and a solid lithium anode is insufficient for storing and supplying the amount of power needed for most electronics. —Li et al.
