Li-ion batteries and other emerging lithium-based battery technologies are currently used to power a wide range of devices, including smartphones, laptops, tablets and cameras. Despite their advantages, batteries containing lithium do not always retain their performance over time.
One of the main reasons for the performance decay observed in some Li-based batteries is that the lithium contained within them sometimes becomes inactive or “dead.” This “dead lithium” can cause capacity decay and thermal runaway, which can ultimately reduce a battery’s lifespan and impair its performance.
Researchers at Zhejiang University of Technology in China and Argonne National Laboratory in the U.S. have recently devised a strategy to restore inactive lithium in Li metal anodes. This strategy, outlined in a paper published in Nature Energy, is based on a chemical reaction known as iodine redox.

There’s a lot of money to be made in nontoxic makeup.
Beautycounter, the startup known for its clean formulations, just hit unicorn status. The startup received an undisclosed investment from the Carlyle Group, raising its valuation to $1 billion. The investment gives the firm a majority stake in Beautycounter and is designed to fuel the company’s growth, including an expansion beyond North America. But it’s also a testament to how mainstream—and lucrative—the clean beauty sector has become.

High-profile entrepreneurs like Elon Musk, venture capitalists like Peter Thiel and Keith Rabois, and big companies like Oracle and HP Enterprise are all leaving California. During Covid-19, Zoom-enabled tech workers are discovering the benefits of remote work from cheaper, less congested communities elsewhere. Though working from home was intended to be a temporary measure for millions of workers in the early days of the pandemic, there is now no clear end in sight. Almost a year later, workers continue to untether themselves from city centers as companies permanently go remote and rethink how they conduct business.
Is this the end of Silicon Valley as we know it? It is my belief that it is—but the reasons why the Silicon Valley party may soon be over run far deeper than the flight of talent. One of the most compelling is that the greatest opportunities will no longer be found in the overbuilt sector of consumer and business internet applications. Instead, they’ll be found in climate tech.

Millions of tiny pieces of plastic are swirling around in Earth’s atmosphere and traveling across entire continents, according to a new study. This environmental problem is likely to get much worse and could have serious effects on human health, experts say.
Microplastics measure less than 0.2 inches (5 millimeters) long, according to the National Oceanic and Atmospheric Administration (NOAA). And previous studies had shown that these microscopic particles can be found in the ocean, bottled water and even our poop, but until now, the atmospheric section of this “plastic cycle” had been poorly understood.
The new study revealed thousands of tons of microplastics already in the atmosphere, with roads as the biggest contributor. Computer modeling also revealed how particles get transported vast distances across the globe and showed that nowhere is safe from the pollution.

Duke University researchers have created a new online resource designed to help local governments, conservation groups, businesses and other stakeholders identify the best technologies to clean up plastic pollution in our oceans or prevent it from getting there in the first place.
The Plastic Pollution Prevention and Collection Technology Inventory includes 52 different technologies, from solar-powered catamarans that use conveyor belts to scoop up floating debris, to underwater bubble tubes that force submerged bits of plastic to the surface where they can more easily be collected.
