Spent lithium-ion batteries contain valuable metals that are difficult to separate from each other for recycling purposes. Used batteries present a sustainable source of these metals, especially cobalt and nickel, but the current methods used for their separation have environmental and efficiency drawbacks. A new technology uses electrochemistry to efficiently separate and recover the metals, making spent batteries a highly sustainable secondary source of cobalt and nickel—the reserves of which are currently dwindling.
A new study, led by University of Illinois Urbana-Champaign chemical and biomolecular engineering professor Xiao Su, uses selective electrodeposition to recover valuable metals from commercially sourced lithium nickel manganese cobalt oxide—or NMC—battery electrodes. The method, published in the journal Nature Communications, produces final product purities of approximately 96.4% and 94.1% for cobalt and nickel, respectively, from spent NMC electrode wastes.
Su said cobalt and nickel have similar electrochemical properties—or standard reduction potentials—making it challenging for chemists to recover pure forms of each metal from battery electrodes.
The new Tesla Model P phone is coming. The best news for Tesla fans.
Designer Antonio De Rose and his ADR Studio Design lab released a clone of the Tesla Phone. It’s fun to show off ADR’s continued design skills.
Rumors are surfacing that Tesla really is planning to make a smartphone. Already, ADR’s concept images are looking a whole lot cooler. Especially for the Tesla fans.
Brazilian Communications Minister Fabio Faria met with the billionaire tech mogul in Austin, Texas. SpaceX would send its satellite internet service, Starlink, to rural schools and health institutions.

From Stargate to Interstellar, wormholes are our favorite method for traveling across fictional universes. But they are also a very serious field of study for some of our greatest minds over the last century. So what’s the holdup? When do we get to wormhole ourselves out of here?

Quasars, X-ray Binaries and Supermassive voids at the center of our galaxies … black holes take many forms. In this episode Matt tells us what these different types of black holes are and how scientists are using VLBI, Very Long Baseline Interferometry, to map the different black holes throughout the known universe.

The Kepler telescope recently noticed a strange partial eclipse that some have speculated could be a Dyson Sphere. Are Dyson Sphere’s possible? Are they practical? What other alternatives to futuristic energy capture do we have to choose from? Why not a kugelblitz — a swarm of black hole powered engines?

Thanks to Curiosity Stream for sponsoring today’s video. ~ In 1984 something strange happened in the village of Dodleston. A BBC Micro was sitting on a counter, when it suddenly started receiving mysterious messages, which appeared to come from the 16th century. This might have gone unnoticed had local teachers, Ken Webster and Peter Trinder, not investigated to find that information was so accurate, it would be almost impossible to fake. This whole event was documented in the book “The Vertical Plane”, published in 1989. But here, tonight, we investigate deep to find out exactly what this is all about.
