Discarded Phone Batteries Turned Into Water-Purifying Carbon
46+ min ago (607+ words) Every year, millions of lithium-ion batteries reach the end of their lives, and most of the graphite inside them is quietly thrown away....
Flower-Powered Carbon Doped With Manganese Boosts Supercapacitors and Solar
2+ hour, 5+ min ago (55+ words) Researchers in India have transformed the delicate purple-and-white flowers of Bauhinia variegata, the mountain ebony tree, into a high-performance carbon electrode material that works in two very different clean-energy devices at once. In a study published in the Springer journal…...
Microbes Turn Renewable Electricity and CO2 Into Valuable Chemicals
2+ hour, 8+ min ago (696+ words) Scientists at Pusan National University have published a comprehensive review showing that microorganisms wired directly to electrical circuits could become the backbone of a carbon-negative chemical industry. In a paper in the journal Advances in Industrial and Engineering Chemistry, Chang…...
Discarded Lithium-Ion Batteries Brought Back to Life With Thermochemical
2+ hour, 43+ min ago (641+ words) Every electric vehicle that rolls off an assembly line today carries within it a promise of cleaner transportation and, eventually, a difficult waste problem. Lithium-ion batteries degrade with use, and when they can no longer hold enough charge to propel…...
Recycled Battery Cathode Material Pulls Toxic Blue Dye from Water Without
3+ hour, 32+ min ago (94+ words) The blue dye that colors denim, candies, and medicines may soon face an unexpected adversary: the discarded remains of old cellphone batteries. In a study published in Discover Industrial Chemistry and Materials, a team of Brazilian researchers led by Eric…...
The Slow Drain: Tiny Electronic Currents Threaten Solid-State Battery
8+ hour, 7+ min ago (583+ words) Solid-state batteries have been heralded as the next great leap in energy storage, promising higher energy densities, improved safety and longer lifetimes than the lithium-ion cells that power everything from smartphones to electric vehicles....
Chloride-Rich Electrolyte Powers a High-Voltage Lithium–Sulfur Battery
8+ hour, 48+ min ago (564+ words) Rechargeable lithium–sulfur batteries have long been heralded as one of the most promising routes beyond the limits of conventional lithium-ion technology. Sulfur is abundant, inexpensive and capable in principle of storing enormous quantities of energy per unit mass....
Singapore built a pilot plant that uses discarded orange, lemon and pineapple peels to dissolve valuable metals out of shredded lithium-ion batteries — the underlying process recovered roughly 90 percent of the cobalt, lithium, nickel and manganese in lab tests
14+ hour, 2+ min ago (217+ words) Somewhere in Singapore's industrial west, a tank of shredded batteries is soaking in a solution that smells faintly of marmalade....
Get the best battery life for your Windows laptop by changing these settings
14+ hour, 18+ min ago (295+ words) If your Windows laptop drains like crazy when away from a charger, adjusting some settings will help you get more out of each charge. It's a terrible feeling to watch your laptop's battery life quickly tick down as you realize…...
Halogen Chemistry Lifts Sulfur Batteries to a Higher Voltage
10+ hour, 16+ min ago (623+ words) Lithium-sulfur batteries have spent decades promising an energy-storage revolution that never quite arrived. On paper, the chemistry is extraordinary: sulfur is abundant, cheap, and capable in principle of storing several times more energy per kilogram than the intercalation cathodes used…...
