First American sodium-ion battery factory will make cells with lifespan of 50,000 cycles that charge in 10 minutes

Posted by in categories: chemistry, energy, sustainability, transportation

Built by Natron Energy, the Edgecombe County facility is planned for 24 GWh of annual capacity, which would turn Natron from a startup into the first sodium-ion battery production juggernaut on US soil.

Sodium-ion batteries are cheaper, safer, with much longer lifespan and faster charging than conventional Li-ion packs.

Chinese companies are already using them in grid-level energy storage systems of local utilities, to balance their renewable energy mix. Some sodium-ion battery packs are even making their way into electric vehicles there, even though the chemistry offers lower energy density than Li-ion batteries.

New technology extracts lithium from brines inexpensively and sustainably

Posted by in categories: chemistry, energy, sustainability, transportation

A new technology can extract lithium from brines at an estimated cost of under 40% that of today’s dominant extraction method, and at just a fourth of lithium’s current market price. The new technology would also be much more reliable and sustainable in its use of water, chemicals, and land than today’s technology, according to a study published in Matter by Stanford University researchers.

Global demand for lithium has surged in recent years, driven by the rise of electric vehicles and renewable energy storage. The dominant source of lithium extraction today relies on evaporating brines in huge ponds under the sun for a year or more, leaving behind a lithium-rich solution, after which heavy use of potentially toxic chemicals finishes the job. Water with a high concentration of salts, including lithium, occurs naturally in some lakes, hot springs, and aquifers, and as a byproduct of oil and natural gas operations and of .

Many scientists are searching for less expensive and more efficient, reliable, and environmentally friendly lithium extraction methods. These are generally direct lithium extraction that bypasses big evaporation ponds. The new study reports on the results of a new method using an approach known as “redox-couple electrodialysis,” or RCE, along with cost estimates.

3D-printed decoupled structural lithium-ion batteries that are stable, robust and customizable

Posted by in categories: 3D printing, energy, sustainability, transportation

The widespread adoption of electric vehicles greatly relies on the development of robust and fast-charging battery technologies that can support their continuous operation for long periods of time. One proposed energy storage solution to improve the endurance of electric vehicles entails the use of so-called structural batteries.

Structural batteries are batteries that can serve two purposes, acting both as structural components of vehicles and solutions. Instead of being external components that are added to an electronic or electric device, these batteries are thus directly embedded into the structure.

Researchers at Shanghai University and their collaborators recently devised a promising strategy to fabricate highly performing structural batteries with customizable geometric configurations. Their strategy, outlined in a paper published in Composites Science and Technology, enables the 3D-printing of structural lithium-ion batteries for different geometrical configurations.

NASA’s Revolutionary X-59 Supersonic Jet Inches Closer to Historic First Flight with Final Tests Underway

Posted by in categories: innovation, transportation

NASA’s X-59 QueSST (Quiet Supersonic Technology) aircraft is on the brink of making history, as it nears its highly anticipated maiden flight.

Designed to break the sound barrier without producing the disruptive sonic boom traditionally associated with supersonic speeds, the X-59 promises to revolutionize air travel.

With a sleek design and innovative technology, the aircraft has the potential to open up a new era of quieter supersonic flights, particularly over land—a feat that has been unattainable since the era of the Concorde.

Volcano erupts after powerful earthquake in Russia’s Far East and scientists warn of a stronger one

Posted by in category: transportation

PETROPAVOVSK-KAMCHATSKY, Russia (AP) — One of Russia’s most active volcanoes has erupted, spewing plumes of ash 5 kilometers (3 miles) into the sky over the far eastern Kamchatka Peninsula and briefly triggering a “code red” warning for aircraft.

The Shiveluch volcano began sputtering shortly after a powerful 7.0 magnitude earthquake struck off Kamchatka’s east coast early Sunday, according to volcanologists from the Russian Academy of Sciences. They warned that another, even more potent earthquake may be on the way.

The academy’s Institute of Volcanology and Seismology released a video showing the ash cloud over Shiveluch. It stretched over 490 kilometers (304 miles) east and southeast of the volcano.

Researchers Develop Innovative Battery Recycling Method

Posted by in categories: engineering, sustainability, transportation

A research team at Rice University led by James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering, is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.

The team has pioneered a new method to extract purified active materials from battery waste as detailed in the journal Nature Communications on July 24. Their findings have the potential to facilitate the effective separation and recycling of valuable battery materials at a minimal fee, contributing to a greener production of electric vehicles (EVs).

“With the surge in battery use, particularly in EVs, the need for developing sustainable recycling methods is pressing,” Tour said.
