Altris Commits To Sodium-Ion Battery Factory In Sweden & More News Here

The sodium-ion battery has been the topic of intense scientific analysis for years, primarily as a result of sodium is among the most considerable components on the earth (it’s the principle ingredient in desk salt), whereas lithium, whereas not precisely uncommon, is far more durable to supply in industrial portions. The largest impediment standing in the way in which of the acceptance of sodium-ion batteries in trade is that they’ve a decrease power density that lithium-based batteries.

But the dominance of lithium batteries is underneath risk these days. The value of lithium has elevated by 700% for the reason that starting of this yr, forcing battery producers and automakers to contemplate choices that have been beforehand not possible. CATL final yr introduced it has created a sodium-ion battery with an power density of 160 wH/kg and expects to extend that to 200 wHkg by 2023. It has already began manufacturing of its first era sodium-ion battery cells.

Altris is a Swedish firm that can also be deeply concerned in manufacturing sodium-ion batteries. According to Chemical and Engineering News, it would construct its first industrial facility at Sandvik Materials Technology’s web site in Sandviken, Sweden. Altris plans to start constructing the plant within the coming weeks and open it in early 2023. The manufacturing unit could have an preliminary capability of two,000 metric tons per yr of its Ferrum cathode materials, which options sodium, iron, carbon, and nitrogen compounds.

On its web site, the corporate says its analysis focuses on the event of electrodes which might be comprised completely of extremely considerable and protected supplies. A pilot manufacturing line is already in operation and demonstrating the feasibility of implementing the sodium cathode expertise as a “drop-in” alternative for typical cathodes. That’s necessary as a result of it means no main adjustments within the manufacturing course of are required.

The firm calls its iron and sodium based mostly electrode materials Fennac, which is quickly produced in massive portions by way of a low power course of. “Fennac is high sodium content Prussian White powder which is a cathode material for the next generation of environmentally friendly sodium ion batteries. Composition is NaxFe[Fe(CN)6] with x>1.9,” the corporate says. “This material is ideal as performance positive electrode in sodium-ion batteries and can be paired against anode materials which do not contain sodium. Ideal storage is under inert conditions in order to maintain quality over the longer term. Nominal voltage 3.25 V on average, capacity ~160 mAh g-1.”

The aggressive power density makes the fabric appropriate for sodium-ion batteries utilized for stationary power storage, to assist the grid and different functions the place a low value various is enticing.

Sodium batteries will not be but prepared to be used in electrical autos, however cling on. The closing chapter hasn’t been written. Battery expertise right this moment is the place videotape recording was within the Eighties. First there was Betamax, then VHS, then Blu-ray, then CDs and now it’s all performed on-line. The inner combustion engine of right this moment is a jewel of engineering prowess, nevertheless it has been in growth for over a century. You would anticipate a lot of the bugs to be labored out by now. (Older readers could keep in mind when a gasoline-powered automotive was thought of prepared for the scrap heap after 50,000 miles.)

Are sodium-ion batteries the following new factor? If lithium, nickel, and cobalt costs stay within the stratosphere, they very properly could possibly be. In the ultimate evaluation, protected, low value grid-scale battery storage for renewable power might be extra necessary within the battle towards fossil gasoline impressed local weather change than constructing electrical automobiles. Pass the salt, please!
