#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."

Geared towards a #teen audience.

On the way to school, a boy is confronted by an enormous man whose hand grabs hold of his school bag and tosses it into the air. The hand pushes him towards a huge padlock, then forces him to enter through the keyhole: the schoolboy is imprisoned in a hazardous lock factory. Like the other children inside, he finds himself forced to operate a high-speed punch press. Struggling to follow the movements of the machine, he cuts off a finger. He tries to run away, but is recaptured.

Back at the factory he starts to cough up blood after inhaling iron particles that will prove lethal: the child dies on the job. Coldly, the hand picks up his body and drops it in the box the padlocks are shipped in, symbol of his murdered innocence.

How can we live with forced child labour? This #India / #Canada co-production is inspired by #Article32 of the United Nations Convention on the #RightsOfTheChild , which particularly upholds the child's right to be protected from economic #exploitation. An #AnimatedFilm without words for 12- to 17-year olds.
