Was the ‘Baghdad battery’ really two cells?
2+ hour, 59+ min ago (445+ words) A new study of the roughly 2000-year-old artefact known as the "Baghdad battery" suggests it was not just a single electrochemical cell " and that when built properly it had much more power than previously thought. The artefact known as the…...
How safe is the next generation of battery chemistries?
1+ week, 3+ day ago (1150+ words) Worker on a production line producing sodium-ion batteries at Namey New Energy Technology in China. The question is, do these new batteries pose any hazards beyond conventional lithium-ion batteries? Solid state and sodium-ion batteries are advancing rapidly but also in…...
Solvent-free ball-milling produces organosodium reagents as sustainable lithium alternative
2+ week, 2+ day ago (151+ words) Ball milling is a straightforward way to produce organosodium reagents, potential replacements for organolithium ones that are becoming more expensive as lithium is in high demand for battery technologies The sodium analogue to ubiquitous organolithium reagents is now easily accessible…...

Global cooperation essential to cut carbon emissions in lithium-ion battery supply chain
2+ mon, 3+ week ago (468+ words) Car battery production is still highly energy intensive and without better recycling the carbon emissions savings from moving transport over to this technology would be far lower Carbon emissions from the lithium-ion battery supply chain could be cut by a…...
Electron transfer plays an underappreciated role in battery charging cycles
3+ mon, 1+ week ago (265+ words) The charging and discharging rates of a wide range of lithium-ion batteries are better explained using model that accounts for both electron and lithium ion transfer, researchers in the US have shown. The findings, which show that ion transfer alone…...
Solar cell progress hinges on more than just materials
3+ mon, 3+ week ago (217+ words) Last year, Oxford PV installed the first commercial solar panels to incorporate perovskites at a solar farm in the US. Perovskite materials have long been hailed as a technology capable of delivering cheap renewable energy on a global scale and…...
Kesterite solar cells break efficiency ceiling after decade-long stall
4+ mon, 1+ week ago (1705+ words) Efficiency breakthroughs: After a decade-long plateau at 12.6% power conversion'efficiency (PCE), recent innovations have pushed it to nearly 17%, with expectations to reach 20% within five years " crossing the threshold for commercial viability. Tandem cell promise: Kesterite's compatibility with silicon makes it a…...
These flexible fuel cells still work after being pierced with toothpicks and cut into pieces
4+ mon, 1+ week ago (361+ words) Highly flexible fuel cells made from cotton yarn could power new wearable electronic devices. The thin, cord-like fuel cells, which convert the chemical energy from methanol into electricity, retain their energy reserves even under extreme stress, and provide a higher…...
Building better batteries with chemistry’s toolbox
4+ mon, 1+ week ago (139+ words) How organic chemistry powers the development of sustainable batteries To push the redox potential upwards, the researchers decorated PDCA and PDFSA with two chlorine or two fluorine atoms at the 1- and 5-positions, stripping the redox centre of even more electrons....
