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. 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.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

The economic benefits of recycling Li-ion batteries are clear, but at present, only a small percentage of them are recycled. In contrast, lead-acid batteries have a 99% recycling rate in the US. The two main processes for recycling lithium-ion batteries are pyrometallurgy and hydrometallurgy.

Mitsubishi and Tokyo Institute of Technology Developing EV Smart Charging from Wind Turbines

Green Car Congress

and the Tokyo Institute of Technology are developing a smart charging system to exploit wind power produced at night to charge electric vehicles. In order to store electricity generated at night, windmill operators need to install sodium-sulfur battery systems, which are as costly as power generators. Mitsubishi Corp.
