Lithium batteries made with asphalt could charge 10 to 20 times faster than the commercial lithium-ion batteries currently available. The researchers developed anodes comprising porous carbon made from asphalt that show exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrates the material’s promise for use in rapid charge and discharge devices that require high-power density. “The capacity of these batteries is enormous, but what is equally remarkable is that we can…

Researchers have created a way to look inside fuel cells to see the chemical processes that lead them to breakdown. Fuel cells could someday generate electricity for nearly any device that’s battery-powered, including automobiles, laptops, and cellphones. Typically using hydrogen as fuel and air as an oxidant, fuel cells are cleaner than internal combustion engines because they produce power via electrochemical reactions. Since water is their primary product, they considerably reduce pollution. The oxidation, or breakdown, of a fuel cell’s…

Researchers have created a small, thin, biodegradable sensor that could monitor the temperature of food in transit. Microsensors are already used in many different applications today, such as the detection of poisonous gases. They are also part of miniaturized transmitter/receiver systems, such as the ubiquitous RFID chips. As the sensors often contain precious metals that are harmful to both the environment and human health, however, they are not suitable for medical applications involving direct contact with the human body or…

A novel compound called 3Q conducts electricity and retains energy better than other organic materials currently used in batteries, researchers report. “Our study provides evidence that 3Q, and organic molecules of similar structures, in combination with graphene, are promising candidates for the development of eco-friendly, high capacity rechargeable batteries with long life cycles,” says Loh Kian Ping, professor in the chemistry department at NUS Faculty of Science. Rechargeable batteries are the key energy storage component in many large-scale battery systems…

Safety concerns regarding lithium-ion batteries have been making headlines in light of smartphone fires and hoverboard explosions. In order to combat safety issues, at team of researchers from Drexel University, led by ECS member Yury Gogotsi, has developed a way to transform a battery’s electrolyte solution into a safeguard against the chemical process that leads to battery fires. Dendrites – or battery buildups caused by the chemical reactions inside the battery – have been cited as one of the main…

By: Timothy H. Dixon, University of South Florida This summer I worked on the Greenland ice sheet, part of a scientific experiment to study surface melting and its contribution to Greenland’s accelerating ice losses. By virtue of its size, elevation and currently frozen state, Greenland has the potential to cause large and rapid increases to sea level as it melts. When I returned, a nonscientist friend asked me what the research showed about future sea level rise. He was disappointed…
