#SodiumIonBatteries offer an alternative to tricky #lithium

Oct 26th 2023

Excerpt: "Fortunately, lithium is not the only game in town. As we report this week, a clutch of firms are making batteries based on sodium, lithium’s elemental cousin. Since sodium’s chemical properties are very similar to those of lithium, it too makes for good batteries. And sodium, which is found in the salt in #seawater, is thousands of times more abundant on Earth than lithium and cheaper to get at. Most of the companies using sodium to make batteries today are also Chinese. But pursuing the technology in the West might be a surer route to energy security than relying heavily on lithium.

"Besides its abundance, sodium has other advantages. The best lithium batteries use #cobalt and #nickel in their electrodes. Nickel, like lithium, is in short supply. #Mining it on land is #EnvironmentallyDestructive. Proposals to grab it from the #seabed instead have caused rows. A good deal of the world’s cobalt, meanwhile, is extracted from small mines in the #DemocraticRepublicOfCongo, where #ChildLabour is common and working conditions are dire. Sodium batteries, by contrast, can use #electrodes built from #iron and #manganese [and wood #lignin], which are plentiful and uncontroversial. Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts.

"Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

Fast-charging #SodiumIon battery uses anodes made from trees

By C.C. Weiss
June 09, 2024

"A month after #NatronEnergy began its first-of-kind sodium-ion battery mass production, Swedish sodium-ion developer #Altris has identified a means of making the LithiumFree batteries even more sustainable. Together with partner #StoraEnso, it's adapting tree pulp-sourced carbon toward use as an anode material.

"A byproduct of wood pulp manufacturing, #lignin has long been investigated for possible use as a more sustainable electrode material. Finnish renewable materials company Stora Enso made headlines in 2022 when it partnered up with Swedish battery manufacturer #Northvolt toward using its proprietary #Lignode material in lithium-ion battery anodes. Stora Enso describes Lignode as a hard carbon material refined from lignin.

"By teaming with Altris, Stora Enso looks to go even more sustainable while further localizing the European battery supply chain. As we looked at when Natron Energy kicked off production a few weeks ago, sodium-ion batteries eliminate the need for rare minerals like lithium, cobalt and nickel, relying on abundant sodium that can be sourced locally without harmful #mining.

"A new sustainable method turns discarded #MobilePhoneBatteries and industrial lignin into a powerhouse material for #SodiumIon batteries.

"It is a stunning example of circular economy innovation. Rather than letting these materials sit in #landfills or go up in smoke, the team from China is giving the waste a high-tech second life.

"When tested as a sodium-ion battery anode, this composite of #nickel-#cobalt sulfides and #lignin-derived carbon delivered electrochemical results."

Lignin wird zu wertvollen Amiden – Forschenden gelingt nachhaltiger Durchbruch

@BlumeEvolution

Sag ich seit Jahren.

Wir hatten sogar schon eine Industrie mit den #RedoxFlowBatterien

Es gab mehrere Hersteller die diese z.b fahrbar auf einem LKW Anhänger gebaut haben um #Konzerte / #Kirmes mit #Strom zu versorgen.

Diese Hersteller gibt es aber nicht mehr.

Die Technik ist auch Uralt und benötigt als SspeicherMaterial #Eisen oder sogar nur #Lignin

Jede #WKA sollte so einen Speicher haben.

Es gibt #WKAs damit

When trees ruled the world

Around 300 million years ago, nature found a new plant strategy. #Lignin. It let plants grow taller by providing a solid structure that gave way to the first trees, scale trees, covering earth for 60M years.

For millions of years there was nothing that could break down the lignin so the trees didn't decompose, they simply fell and were gradually covered.

It's these trees, not dinosaurs, where our fossil fuels come from.

I wrote a little #lignin #plantbiology perspective article entirely in #rstats #Quarto a while back (https://leonardblaschek.github.io/assets/2024_JAFC/index.html) and had a blast. I ran into a couple of bugs along the way, but the quarto team was lightning fast in fixing them.

The only thing I'm still wrapping my head around is efficient co-writing with colleagues not using git. Any better ideas than rendering to .docx and manually copying track changes into the source file?

While wood remains a critical resource for many industries, the growing of trees and general forestry can't keep up. To make this process sustainable and reduce logging, more efficient trees need to be made.

NC State scientists have been working on making trees with low lignin and high wood properties.

Using CRISPR and predictive modeling, they have isolated multiple gene editing targets for such improvements.
