New battery design for electric cars would stack up to 1,000-km range - New Atlas. One of the big stumbling blocks preventing the wide scale acceptance of electric cars is dreaded range anxiety.
With an average range of around 100 mi (161 km) per charge, all-electric vehicles still can't compete with more conventional cars – especially if lights, windscreen wipers, or air con are needed. To level the playing field a bit, Fraunhofer is working on a new battery design that could increase an electric car's range to 1,000 km (621 mi). Electric cars don't have a single battery, but a collection of battery packs made of hundreds or thousands of individual battery cells that are packed in and wired together. These separate battery cells each require a housing as well as terminals, wiring, cables, and electronic monitors, which all combine to take up 50 percent of the space of a whole battery pack.
Additionally, all those electrical connections sap away current through resistance. EMBATT takes its cue from another electrical power source, the fuel cell. Source: Fraunhofer. How recycled glass bottles can become better batteries. Ask a regular smartphone user how they'd like to see the devices improved, and it's a safe bet that longer battery life would be close to the top of the list.
Batteries made with silicon anodes could help boost that, and now a team at the University of California Riverside (UCR) has shown that these batteries can be environmentally friendly too, by being sourced from glass bottles headed for the scrap heap. Lithium-ion batteries power everything from smartphones to electric vehicles, and conventionally they're made with a lithium cathode and a graphite anode. But as useful as this setup has been over the years, the ceiling on their efficiency has all but been reached, prompting researchers to look to our old friend silicon as an alternative anode.
While they have the potential to store up to 10 times more energy than graphite, silicon anodes aren't quite as durable, with the expansion and contraction that comes with regular use cracking the material and wearing them down much faster. Fern-leaf inspires electrode for high density solar energy storage. Solar cells are constantly getting better at collecting energy from sunlight, but their ability to store it isn't improving quite as fast.
Made from graphene and with a fern-inspired fractal structure, engineers at RMIT University have developed a new prototype electrode that could enable solar harvesting and storage systems that are thin, flexible and have high capacity. While the sun is attractive as an energy source, solar-powered devices usually have to fall into two categories: those with big bulky setups, or smaller ones that don't need as much power. The RMIT team's new electrode is designed to bridge that gap, with a better energy density inspired at the microscopic level by the repeating pattern (called a fractal) seen in the veins of a species of American fern. "The leaves of the western swordfern are densely crammed with veins, making them extremely efficient for storing energy and transporting water around the plant," says Min Gu, co-author of the study.
Can the Goodenough lab invent the battery to jumpstart the electric car revolution? He's the 94-year-old co-inventor of the lithium-ion battery.
She's a physicist with a less than conventional idea of building a better battery. Together, can they develop the technology that will finally deliver us from our dependence on fossil fuels and kickstart the promised electric vehicle (EV) revolution? In 2014, Maria Helena Braga, a physicist at the University of Porto, published a paper on a novel type of superionic glasses that could solve the problems preventing solid electrolytes from being used in commercial batteries: their poor ionic conductivity at acceptable temperatures and lack of stability with respect to the metal. The paper attracted the attention of several companies who were interested in commercializing the glasses. One last big idea Murchison told the professor about Braga's work, one thing led to another and within a year, she was at the university putting her glasses through the exacting paces of his lab.
Diamonds turn nuclear waste into nuclear batteries. One problem with dealing with nuclear waste is that it's often hard to tell what's waste and what's a valuable resource.
Case in point is the work of physicists and chemists at the University of Bristol, who have found a way to convert thousands of tonnes of seemingly worthless nuclear waste into man-made diamond batteries that can generate a small electric current for longer than the entire history of human civilization. How to dispose of nuclear waste is one of the great technical challenges of the 21st century.
The trouble is, it usually turns out not to be so much a question of disposal as long-term storage. If it was simply a matter of getting rid of radioactive material permanently, there are any number of options, but spent nuclear fuel and other waste consists of valuable radioactive isotopes that are needed in industry and medicine, or can be reprocessed to produce more fuel.
The video below explains how the nuclear diamond battery works. Flexible supercapacitor process brings phones that charge in seconds a step closer. Researchers from the University of Central Florida (UCF) have devised a technique for creating flexible supercapacitors that not only store more energy than comparable devices, but can also be fully-charged in seconds and continue to be recharged more than 30,000 times without affecting performance or capacity.
"If they were to replace batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn't need to charge it again for more than a week," said postdoctoral associate Nitin Choudhary. Working in the NanoScience Technology Center at UCF (and building on previous work in supercapcitor nanowire technology), the researchers realized their breakthrough by experimenting with the application of newly-discovered 2D materials known as transition-metal dichalcogenides (TMDs) only a few atoms thick to coat 1D nanowires.
However, like many nascent technologies, the UCF flexible supercapacitor has not yet been developed sufficiently for release to market. The key to better rechargeable batteries may be in your blood. Traditional lithium-ion batteries may be on the way out, as scientists continue to overcome the obstacles holding back the longer-lasting lithium-oxygen batteries.
The main issue is lack of efficiency and the build-up of lithium peroxide, which reduces the electrodes' effectiveness. But now a team at Yale has used a molecule found in blood as a catalyst that not only improved the lithium-oxygen function, but may help reduce biowaste. Lithium-oxygen, or lithium-air batteries, have the potential to hold a charge for much longer than traditional lithium-ion batteries and extend the life of devices like phones to several weeks before they'd need to be recharged. But before those dreams can become a reality, the problems of efficiency and lithium peroxide build-up need to be solved.
Previous studies have tried to fight lithium peroxide by keeping the oxygen in the cell as a solid, and by modifying the electrode to produce lithium superoxide instead. Solid-state lithium battery knows when to keep its cool. One of the new frontiers in battery technology is creating safer versions of the ubiquitous lithium-ion battery, like those that power electric cars and the computers or phones you read these words on.
These little suckers are great at packing large amounts of energy into tight spaces, but can run into trouble at high temperatures. Versions that replace combustible, liquid electrolytes with solid parts is one way this problem might be overcome and researchers have just thrown up one possible answer, building a solid-state lithium-ion battery that can be heated all the way up to 100° Celsius without bursting into flames. If you've ever left your phone out in the sun on a summer's day, you may recall an on-screen temperature warning, advising you to let the phone cool down before using it again. This is because the liquid electrolyte within the battery can ignite or swell up under high temperatures. Eco-friendly battery gets vitamin B2 boost.
Using strands of vitamin B2 that originated in genetically-modified fungi, researchers at the University of Toronto (U of T) have developed a battery with high capacity and high voltage that may pave the way for environmentally-friendly, metal-free batteries.
Claimed by the researchers to be comparable to existing high-energy lithium-ion batteries, with a capacity of around 125 mAh and a 2.5 V potential, the U of T unit uses flavin derived from vitamin B2 as the battery's cathode rather than a lithium-based material. "We've been looking to nature for a while to find complex molecules for use in a number of consumer electronics applications," says Dwight Seferos, an associate professor in the U of T department of chemistry. "When you take something made by nature that is already complex, you end up spending less time making new material.
" "Organic chemistry is kind of like Lego," said Serefos. "B2 can accept up to two electrons at a time," said Seferos. Toyota battery breakthrough means magnesium could eventually replace lithium. Engineers at the Toyota Research Institute of North America (TRINA) think they've found the secret to using magnesium in rechargeable batteries.
This would replace lithium as a safer, more energy-dense option for batteries in everything from cell phones to cars. Magnesium has been considered a potential replacement for lithium in rechargeable batteries for some time. Lithium is not stable in air and can combust when exposed, so to make lithium-ion batteries safer, the ions are reduced and the lithium is embedded into graphite rods.
This reduces the amount of metal (reducing density), which limits the amount of power the li-ion battery can store. To increase density, engineers have toyed with the mix of lithium and graphite and the shape of the cells, but the balance is tricky. Adding silicon-sulfur into 3D graphene makes for game-changing battery potential.
Researchers in China believe they're cracked the code on the elusive lithium-sulfur (Li-S) battery. Using three-dimensional (3D) graphene, the Beihang University researchers structured Li-S in such a way that they show high, real-world potential on both the cathode and anode sides. Chemists have long known that lithium-sulfur has huge potential as a next-generation battery solution, combining the strengths of a fuel cell (very energy dense) with the strengths of a battery (self-contained energy storage) – all in a package that is extremely environmentally-friendly and that has a low cost of manufacture.
The problem is that cathodes of sulfur and lithium have lots of material loss due to the solubility of polysulfides, and are not often efficient because sulfur has insulative properties rather than conductive. Power dense zinc-manganese power unit as cheap as a car battery. A team of scientists working on analyzing energy flows in prototype zinc-manganese batteries have stumbled upon a new way to make these power cells much more reliable, with many more recharge cycles than the humble lead-acid car battery, but costing around the same to produce. The creators claim that the new battery could become an inexpensive, ecologically-sound alternative for storing energy from renewable sources and a high-density solution for storing excess energy from the power grid.
Working at the Department of Energy's Pacific Northwest National Laboratory (PNNL), the researchers discovered a new way to approach the reliability problems of zinc-manganese batteries, that were cheap and easy to make from abundant materials, but which would fail after only a few charge cycles. Much to the surprise of the PNNL team, however, a range of tests actually showed that the device being analyzed was undergoing a completely different process. And it worked. Urine-powered battery offers cheap energy source. When most people think of bacteria and urine together, chances are good they think of a not-so-pleasant infection.
For researchers at the University of Bath however, unifying these two thoughts led to the development of a battery that could harness "pee power" to bring energy to parts of the world that might not otherwise have access to it. Working with colleagues from Queen Mary University of London and the Bristol Bioenergy Centre, the Bath researchers came up with a type of microbial fuel cell (MCF) that is powered by human urine. MFC's are devices that use bacteria to perform reduction/oxidation reactions on organic material like banana skins or, in this case, urine. When such a reaction occurs, electrons are swapped around between molecules and electricity is produced. By causing this reaction to take place in a closed system with an anode and a cathode, a battery is formed. The next step for the researchers is to figure out how to up the energy output of the urine-based MCFs. Experimental battery charges and recharges via bacteria.
Inside your body, the wrong kind of bacteria can sap you of energy. Inside a battery, however, it turns out that the right kind of bacteria can cause an energy boost that might be able to help power our lives. That's the finding from researchers in the Netherlands, who've just developed a bacteria-based battery that they were able to charge and discharge 15 times in a row. The battery combined two technologies. The first is that of a microbial fuel cell in which electricity is produced when electrons are lost by one molecule and gained by another as they undergo an reduction/oxidation (redox) reaction. The second is microbial electrosynthesis, a process in which the electricity produced is converted back into chemicals be be reused in the battery.
Lithium-ion battery boost could come from "caging" silicon in graphene. A team at Stanford claims to have made a battery breakthrough that could boost the performance of lithium-ion batteries and also make them smaller and lighter. The researchers managed to remove two long-standing barriers to these improvements by putting silicon particles in graphene "cages. " To improve capacity in recent years batteries have begun to use silicon anodes, which have more capacity than the graphite conventionally used.
