Yes, one day, you too may be able to fully recharge your plug-in vehicle's battery in the amount of time it takes to decelerate down one of those runaway truck ramps. Assuming your brakes actually work, of course.
Some automakers want to get serious about bringing hydrogen-powered fuel cell vehicles to market if a big wall can be climbed – the one that puts the cost of H2 vehicles out of reach for some OEMs and at least $50,000 for others. That number could slide down thanks to researchers from South Korea, Case Western University and University of North Texas who have discovered an inexpensive and easily produced catalyst that could replace pricey platinum, the catalyst for the required oxygen-redu
In work recently published in the Journal of Applied Physics, a University of Technology Sydney (UTS) team led by professor Guoxiu Wang presented reproducible test results showing that graphene paper has the potential to revolutionize the automotive industry. How? Well, researchers at UTS have milled raw graphite by purifying and filtering it with chemicals to reshape and reform it into graphene nanosheets. We should explain.
In the coming decades, hybrids, and maybe even all-electric vehicles, may cruise without batteries. Instead, the energy in these vehicles of the future will be stored in a supercapacitor which could be recharged in minutes, possibly seconds. We've heard of the potential of supercaps (and ultracapacitors) before, but researchers have just announced they've overcome an obstacle to this device development. In the lab, they have developed supercaps with an energy density equivalent to that found in
