How #chemists turned #bourbon waste into #supercapacitors
Hydrothermal carbonization can directly convert #stillage into hard or #ActivatedCarbon. Cossio & Guzman used activated carbon as #electrodes, creating double-layer #capacitors by putting liquid electrolyte between them. Proof-of-concept devices were able to store as much as 48W/kg. Built a hybrid device, with one activated carbon electrode and one hard carbon electrode, stored as much as 25 times the energy per kg

#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."

Muir Vidler: Stereo EEG Self-Portrait, 2023
This was taken after a surgical procedure to implant #electrodes into Vidler’s #brain. The procedure is carried out on people who have #epilepsy that can’t be controlled by medication and is used to identify which area of the brain is causing the seizures, and can determine whether they are eligible for brain surgery. Vidler took this picture on the first day that the electrodes were inserted, and he had to keep them in for seven days
