If you’ve ever used a smartphone for more than a year or two, you know that the lithium ion batteries degrade over time and refuse to hold a charge like they used to when they were new—but the reason why has been little understood. But research published today in Nature Materials could have a few […]

Lithium-ion battery usage has grown exponentially over the past 25 years as consumers find them in an increasing number of handheld and wearable electronic devices, as well as electric vehicles. Meanwhile, graphite anode materials have not changed during this time and has begun to reach its technological limits, which prevents further advancements in battery capacity. […]

There’s been a lot of buzz in the battery industry about the growth of lithium-ion batteries and how they will grab market share from lead-acid as the need for efficient energy sources in electric vehicles and other applications. But while lithium-ion is growing rapidly, particularly for new applications, lead-acid batteries are alive and well, according […]

Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding—and these golden sculptures have resisted corrosion, wear, and environmental degradation for thousands of years. In a new study at the University of Illinois at Urbana-Champaign, Sameh Tawfick was inspired by this […]

Chinese researchers have made breakthroughs using composite materials with sodium carbonate to produce a rechargeable battery that pulls carbon dioxide from the air for its discharge. A team led by Chen Jun, a professor from Nankai University’s College of Chemistry in Tianjin, has assembled the 350 mAh capacity and 183 Wh/kg energy density battery, the […]

Batteries are our lifeblood. Lithium-ion power cells, first commercialized by Sony in 1991, enable nearly every 21st century convenience: Phones, laptops, wireless headphones, cordless power tools — even electric vehicles. But like the other great conveniences of our modern age — automobiles and air travel — on the rare occasions lithium batteries go wrong, they […]

Several global metals producers have set their sights on Indonesia’s nickel reserves to tap an expected surge in demand for the metal for electric vehicle batteries. Sumitomo Metal Mining Co Ltd (SMM) said on Thursday that it and nickel miner PT Vale Indonesia are conducting a feasibility study to build a nickel processing project in […]

In 2016, Briggs Automotive Company (BAC) developed a vehicle made with graphene in its bodywork. Now, BAC received funding to undertake graphene research, with a view to pushing the technology towards production-readiness for the automotive industry. The road-legal, single-seater supercar – the BAC Mono – received the Niche Vehicle Network (NVN) grant alongside Haydale Composite […]

First Graphene has announces the release of its PureGRAP graphene products. Over the last five months FGR’s management has worked with various universities and on its own production processes to ensure it could consistently produce a suitable range of products. The initial product includes PureGRAPH graphene products with lateral sizes of 20µm, 10µm and 5µm. […]

What happens to gadgets when you’re done with them? Too often, they explode. As we enter new-gadget buying season, spare a moment to meet the people who end up handling your old stuff. Isauro Flores-Hernandez, who takes apart used smartphones and tablets for a living, keeps thick gloves, metal tongs and a red fireproof bin […]
