Le sud de la RDC fournit environ 70% du cobalt mondial. Cette région est riche en cuivre, cobalt et uranium. #Cobalt et #uranium se trouvent souvent dans les mêmes roches.
Les auteurs recommandent des contrôles des cargaisons, un suivi sanitaire des travailleurs et des traitements obligatoires pour isoler l’uranium des eaux et populations.

The south of DRC supplies about 70% of world's cobalt. #Cobalt and #uranium are often found in the same rocks.
The authors recommend cargo inspections, health monitoring for workers, & mandatory treatments to isolate uranium from water & populations.

#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."

New method converts old phones and paper industry #waste into #GreenBattery tech
Scientists have created a sustainable, cost-effective, and highly efficient solution that promotes a #CircularEconomy while supporting the transition to greener #EnergyStorage.

Feb 20, 2026 06:59 AM EST"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."

As #Norway Considers #DeepSeaMining, a Rich History of Ocean Conservation Decisions May Inform How the Country Acts
In the past, scientists, industry and government have worked together in surprising, tense and fruitful ways
by Christian Elliott, April 21, 2025
"At the #Arctic #MidOceanRidge off the Norwegian coast, molten rock rises from deep within the Earth between spreading tectonic plates. Black smoker vents sustain unique ecosystems in the dark. Endemic species of long, segmented bristle worms and tiny crustaceans graze on bacteria mats and flit among fields of chemosynthetic tube worms, growing thick as grass. Dense banks of sponges cling to the summits and slopes of underwater mountains. And among all this life, minerals build up slowly over millennia in the form of #sulfide deposits and #manganese crusts.
"Those minerals are the kind needed to fuel the global green energy transition—#copper, #zinc and #cobalt. In January 2024, Norway surprised the world with the announcement it planned to open its waters for exploratory deep-sea mining, the first nation to do so. If all went to plan, companies would be issued licenses to begin identifying mineral deposits as soon as #Spring2025. To some scientists who’d spent decades mapping and studying the geology and ecology of the Norwegian seabed and Arctic Mid-Ocean Ridge, the decision seemed premature—they still lacked critical data on the area targeted for mining. The government’s own Institute of Marine Research (IMR) accused it of extrapolating from a small area where data has already been collected to the much larger zone now targeted
“ 'Our advice has been we don’t have enough knowledge,' says Rebecca Ross, an #ecologist at IMR who works on Norway’s #Mareano deep-sea mapping initiative. She says the decision was based solely on the #geology of the area. Taking high-resolution scans of the seabed and sampling its geology is the first step when research ships enter a new area, but critical biological and ecological research is more difficult and tends to come later—which is the case on the ridge area targeted for mining. Ross says it’s certain that area contains vulnerable marine ecosystems that would be affected by the light and noise pollution and sediment plumes generated by mining. The IMR estimates closing the knowledge gap on the target area could take ten years.
"The same conflict, with a partial scientific understanding misinterpreted and used to justify resource extraction, is playing out in the #Pacific, where mining pilot projects are already underway in international waters. Years before, scientists funded by industry scouted the #seabed there, discovering both valuable minerals and new forms of life."

@Timmy No need to discuss #alumium or #manganese (if you're not familiar with the latter, it's the most common alloying agent in #steel - it's everywhere).
#Cobalt usage has been steadily declining (a couple decades ago it was as high a % as the #nickel), and there's hope it will be entirely eliminated in the coming years - but as for now it's still in use. Cobalt is the most expensive of the metals (offset by its low percentage), which is a major factor driving the work to eliminate it.

@Timmy As the #LFP patents have been expiring, and it uses no nickel, its use has been increasing dramatically (despite giving lower range, and some other disadvantages).
For longer range, one uses, as mentioned, the nickel-based chemistries. These #cathodes are mixed metal oxides, usually in the ballpark of 80% (or higher) nickel, 10% (or lower) #cobalt, and 10% (or lower) #alumium or #manganese.
