Norfolk Southern Railway No. 999 is the first all-electric, battery-powered locomotive in the United States. But when one of the thousand lead-acid batteries that power it dies, the locomotive shuts down. To combat this problem, a team of Penn State University researchers is developing more cost-effective ways to prolong battery life.
The Federal Laboratory Consortium announced this week that the Department of Energy national laboratory in Richland is receiving three 2013 Excellence in Technology Transfer awards in recognition for creating technologies or processes that can store large amounts of renewable energy until it's needed, fight cancer and detect explosives, and then moving the innovations to the marketplace.
Research at the University of Gothenburg and Chalmers University of Technology has resulted in a new type of machine that sorts used batteries by means of artificial intelligence (AI). One machine is now being used in the U.K., sorting one-third of the country's recycled batteries.
A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road. Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes—in the "current collector," a sheet of copper which facilitates electron transfer between the electrodes and the car's electrical system.
Here's a reason to be glad about madder: The climbing plant has the potential to make a greener rechargeable battery. Scientists at Rice University and the City College of New York have discovered that the madder plant, aka Rubia tinctorum, is a good source of purpurin, an organic dye that can be turned into a highly effective, natural cathode for lithium-ion batteries.
According to new research by the University of Delaware, renewable energy could fully power a large electric grid 99.9% of the time by 2030 at costs comparable to today’s electricity expenses. The study’s authors developed a computer model to consider 28 billion combinations of renewable energy sources and storage mechanisms, each tested over four years of historical hourly weather data and electricity demands.
The U.S. Department of Energy has announced that a multipartner team led by Argonne National Laboratory has been selected for an award of up to $120 million over five years to establish a new Batteries and Energy Storage Hub. The Hub will combine the R&D firepower of five DOE national laboratories, five universities, and four private firms in an effort aimed at achieving advances in battery performance.
Led by Rice University chemist James Tour, researchers have successfully grown forests of carbon nanotubes that rise quickly from sheets of graphene to astounding lengths of up to 120 μm. That translates into a massive amount of surface area, the key factor in making things like energy-storing supercapacitors. The 3D structure connects graphene to nanotubes with covalent bonds, resulting in a stable structure.
Catalysis is an incredibly valuable tool in the field of chemistry, but it typically requires precious metals that are both expensive and potentially harmful to the environment. Researchers in Sweden say they have discovered that copper, which is not typically known for its catalytic properties, had unexpectedly been responsible for catalytic activity as part of research into iron catalysts.
Engineering researchers at the University of Arkansas have developed a thermal energy storage system that will work as a viable alternative to current methods used for storing energy collected from solar panels. Incorporating the researchers' design into the operation of a concentrated solar power plant will dramatically increase annual energy production while significantly decreasing production costs.
Lithium batteries are used in many devices such as cell phones, computers, and cameras, among others. University of Delaware doctoral student Wei-Fan Kuan is investigating ways to improve membranes used in lithium batteries by capitalizing on the innate properties of block copolymers.
An experimental device invented at the University of Michigan is able to convert energy from a beating heart, enough to provide electricity to power a pacemaker. The innovation, which relies on piezoelectricity, could eliminate the need for surgeries to replace pacemakers with depleted batteries.
Researchers at Rice University have refined silicon-based lithium-ion technology by literally crushing their previous work to make a high-capacity, long-lived, and low-cost anode material with serious commercial potential for rechargeable lithium batteries.
Solar, wind and other renewable energy sources reduce consumption of fossil fuels but also pose challenges to the electrical grid because their power generation fluctuates. A team of researchers at Stanford and SLAC National Accelerator Laboratory has developed a mix of materials that shows promise as a cost-effective alternative to standard batteries—able to quickly and efficiently charge and discharge their energy over thousands of charges, with no energy loss after 1,000 charges.
Exactly what goes inside advanced lithium-air batteries as they charge and discharge has always been impossible to observe directly. Now, a new technique developed by Massachusetts Institute of Technology researchers promises to change that, allowing study of this electrochemical activity as it happens.
Researchers from North Carolina State University have developed a new technique that allows users to better determine the amount of charge remaining in a battery in real time. Using the researchers' new technique, models are able to estimate remaining charge within 5%.
A Washington state firm with a 27,000 square foot manufacturing and design facility in Mukilteo has signed a license agreement with Battelle to further develop and commercialize a type of advanced battery that holds promise for storing large amounts of renewable energy and providing greater stability to the energy grid.
Anyone who owns an electronic device knows that lithium-ion batteries could work better and last longer. Now, scientists examining battery materials on the nanoscale reveal how nickel forms a physical barrier that impedes that shuttling of lithium ions in the electrode, reducing how fast the materials charge and discharge. The research also suggest a way to improve the materials.
Researchers at Rice University and from Belgium have developed a way to make flexible components for rechargeable lithium-ion batteries from discarded silicon.

By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell uses mechanical energy more efficiently than systems using separate generators and batteries.
After making a sheet of “paper” from the world’s thinnest material, graphene, Rensselaer Polytechnic Institute scientists zapped it with a laser. The light blemished the ultrathin paper with countless cracks, pores, and other imperfections.
