In a report published in NANO, a team of researchers from Sichuan University of Science and Engineering, China have developed N-doped carbon encapsulated transition metal catalysts for oxygen reduction reactions and oxygen evolution reactions to optimize performance of zinc-air batteries.
Lithium-ion batteries are recognized for their high energy density in everything from mobile phones to laptop computers and electric vehicles, but as the need for grid-scale energy storage and other applications becomes more pressing, researchers have sought less expensive and more readily available alternatives to lithium.
For decades, researchers have looked for ways to eliminate cobalt from the high-energy batteries that power electronic devices, due to its high cost and the human rights ramifications of its mining.
Making the transition to a renewable energy future will have environmental and long-term economic benefits and is possible in terms of energy return on energy invested (EROI), UNSW Sydney researchers have found.
For the past century, the world has relied on combustion engines powered by fossil fuels for transportation, but now lithium-ion battery-powered vehicles are emerging as sustainable successors. As major vehicle producers, European manufacturers are looking to establish their own lithium-ion battery market to compete with firms in Asia and the US. A new report in Chemical & Engineering News , the weekly newsmagazine of the American Chemical Society, explores the challenges and opportunities powering Europe's mission.
The project is the culmination of a U.S. Department of Energy ARPA-E project that began in 2014 with $3.3 million in funding and involved years of prototype development at Tulane and field testing in San Diego.
Shouyi Wang, associate professor of industrial engineering at The University of Texas at Arlington, is using a three-year, $466,068 grant from the National Science Foundation to determine how to meet the demands of an extremely dynamic and uncertain energy market. Electrical engineering Professor Wei-Jen Lee and industrial engineering Professors Victoria Chen and Jay Rosenberger are co-principal investigators on the project.
The catastrophic effects of global environmental degradation, health deterioration and diminishing energy resources are demanding remedy measures aimed at environmental conservation, health interventions and harnessing of the abundant and renewable energy resources.
A team of researchers at the Nanyang Technological University, Singapore has created a perovskite solar mini module that has recorded the highest power conversion efficiency of any perovskite-based device larger than 10 cm2.
Cell phone batteries often heat up and, at times, can burst into flames. In most cases, the culprit behind such incidents can be traced back to lithium batteries.
