#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."

"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."

Critique des visées impérialistes de Trump au Groenland, l’Europe n’est pas en reste quant au partenariat qu’elle mène avec le Rwanda sur les matières premières. La majorité du tantale exporté par ce pays est pillé en République démocratique du Congo.
' "#TheElementsOfPower: A Story of War, Technology, and the Dirtiest Supply Chain on Earth," a new book by journalist #NicolasNiarchos, paints a semi-apocalyptic vision of that #cobalt’s origins: corrupt bargains between politicians and foreign companies, displacement and environmental destruction, cave-ins that bury miners alive.'
