The inspiration for the next generation of robots comes from the animal and insect world.

Data from outage tracking website Downdetector showed more than 5,000 reports in the UK alone.

Mobile phone batteries with a lifetime up to three times longer than today’s technology could be a reality thanks to an innovation led by engineers at RMIT University.

Rather than disposing of batteries after two or three years, we could have recyclable batteries that last for up to nine years, the team says, by using high-frequency sound waves to remove rust that inhibits battery performance.

The research is published in Nature Communications.

For high-cobalt cathodes such as lithium cobalt oxide (LCO) conventional pyrometallurgical (see section ‘Pyrometallurgical recovery’) or hydrometallurgical (see section ‘Hydrometallurgical recovery’) recycling processes can recover around 70% of the cathode value¹¹. However, for other cathode chemistries that are not as cobalt-rich, this figure drops notably¹¹. A 2019 648-lb Nissan Leaf battery, for example, costs US$6,500–8,500 new, but the value of the pure metals in the cathode material is less than US$400 and the cost of the equivalent amount of NMC (an alternative cathode material) is in the region of US$4,000. It is important, therefore, to appreciate that cathode material must be directly recycled (or upcycled) to recover sufficient value. As direct recycling avoids lengthy and expensive purification steps, it could be particularly advantageous for lower-value cathodes such as LiMn₂O₄ and LiFePO₄, where manufacturing of the cathode oxides is the major contributor to cathode costs, embedded energy and carbon dioxide footprint⁹⁵.

Direct recycling also has the advantage that, in principle, all battery components²⁰ can be recovered and re-used after further processing (with the exclusion of separators). Although there is substantial literature regarding the recycling of the cathode component from spent LIBs, research on recycling of the graphitic anode is limited, owing to its lower recovery value. Nevertheless, the successful re-use of mechanically separated graphite anodes from spent batteries has been demonstrated, with similar properties to that of pristine graphite⁹⁶.

A team at the US Department of Energy’s Oak Ridge National Laboratory has developed a utility-scale solar and storage project that can provide power to both AC and DC high-voltage lines, and thus shore up grid stability – here’s how it works.

Most of the US power grid uses alternating current, or AC, which constantly switches the direction of electron flow. But solar and battery storage uses direct current, or DC, that flows in a single direction.

The US power grid includes a smaller number of high-voltage DC lines that are more efficient at delivering bulk power over long distances or to remote regions.

US semiconductor maker Wolfspeed plans to build a chip factory in Germany, which could benefit domestic EV production and the EU chip sector.

Quarks are the smallest form of matter that we know of. So small, in fact, that studying it in any meaningful way has proven nearly impossible over the past several decades. That’s because quarks and their counterpart gluons are the small pieces of the puzzle that make up the nucleons in an atom.

Rachel Bronson, PhD, president and CEO, Bulletin of the Atomic Scientists, said: “We are living in a time of unprecedented danger, and the Doomsday Clock time reflects that reality. 90 seconds to midnight is the closest the Clock has ever been set to midnight, and it’s a decision our experts do not take lightly. The US government, its NATO allies and Ukraine have a multitude of channels for dialogue; we urge leaders to explore all of them to their fullest ability to turn back the Clock.”

The Doomsday Clock’s time is set by the Bulletin of the Atomic Scientists’ Science and Security Board with the support of the Bulletin’s Board of Sponsors, which includes 10 Nobel Laureates. Previously, the Doomsday Clock had been set at 100 seconds to midnight since 2020.
