Ensuring the power grid keeps the lights on in large cities could be easier with a new battery design that packs far more energy than any other battery of its kind and size. The new zinc-polyiodide redox flow battery, described in Nature Communications, uses an electrolyte that has more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid.

Bendy battery promises safe, speedy charging | The Energy Future

Bendy battery promises safe, speedy charging | The Energy Future

APRIL 19, 2015 MIKE BAILEY LEAVE A COMMENT

From BBC: Scientists have built a flexible aluminium battery which they say could be a cheap, fast-charging and safe alternative to current designs. The protoype consists of a soft pouch, containing aluminium for one electrode and a graphite foam for the other – all surrounded by a special liquid salt.

Unlike the transistor, the lithium-ion battery has not won a Nobel Prize. But many people think it should. The lithium-ion battery gave the transistor reach. Without it, we would not have smartphones, tablets or laptops, including the device you are reading at this very moment. There would be no Apple. No Samsung. No Tesla.

In 1980, [John Bannister] Goodenough, a whip-smart physicist then aged 57, invented lithium-ion’s nervous system. His brainchild was the cobalt-oxide cathode, the single most important component of every lithium-ion battery. From Mogadishu to Pago Pago, from Antarctica to Greenland, and all lands in between, Goodenough’s cathode is contained in almost every portable electronic device ever sold. Others have tried to improve on the cobalt-oxide cathode, but all have failed.

Today, at 92, Goodenough still goes to his smallish office every day at the University of Texas at Austin. That, he says, is because he’s not finished. Thirty-five years after his blockbuster, the electric car still can’t compete with the internal combustion engine on price. When solar and wind power produce electricity, it must be either used immediately or lost forever—there is no economic stationary battery in which to store the power. Meanwhile, storm clouds are gathering: Oil is again cheap but, like all cyclical commodities, its price will go back up. The climate is warming and becoming generally more turbulent.

In short, the world needs a super-battery. That, “or I’m sorry we’re going to have wars on wars fighting over the last reserves of this, that or the other and we’re going to have global warming beyond anything we can bear,” Goodenough says.

The good news is that Goodenough has one last idea. He’s working on it with yet another crop of post-doctoral assistants. “I want to solve the problem before I throw my chips in,” he says. “I’m only 92. I still have time to go.”

New, high-energy rechargeable batteries

Researchers develop molten air battery with commercial potential

Molten air batteries have significantly increased storage capacity over lithium batteries.

June 27, 2014

While electric vehicles offer many advantages–including reducing greenhouse gas emissions and the country’s dependence on imported petroleum–at least one barrier stands in the way of their large-scale adoption: “range anxiety.”

Baby, you're so hot, you're making my phone charge

They always say that heat can be detrimental to your smartphone; keep it out of elevated temperatures, don’t let your phone overheat and don’t throw your phone in the oven. One reason is because heat could cause damage to your battery. Heat actually causes a battery’s fluid to evaporate, meaning the loss of electrolytes; leading to permanent internal damage. Increased temperatures make for an increased rate of chemical reactions. While it may seem as through you are getting better performance due to these faster reactions, you actually cause the self-discharge rate to double with each 10°C increase in temperature.

After reading that, you may think it’s not so hot being so hot. Over at the Massachusetts Institute of Technology, researchers have been working on a way to tap into ambient heat and convert it into usable electrical power. They’ve developed a button sized battery, that self-charges using low heat; roughly between 20°C and 60°C. This means the battery could charge while sitting in your pocket; perhaps faster if it’s in your back pocket, after you’ve eaten a burrito.

Dr Gang Chen, head of the mechanical engineering department at MIT, who led the work, said the technology could lead to new mobile phone batteries that can be charged without needing to be plugged in. He said: ‘It is a self-powered device and may be attractive for places without electric grid.

‘To generate enough power for practical applications (such as in mobile phones), better material and system designs are needed, and we are working on it.

‘With further development, there is potential to use such batteries to convert low grade heat into electricity at an attractive cost for broader applications. It uses inexpensive materials. It may have potential application for harvesting thermal energy from the environment, especially in remote areas.’

The team took advantage of the thermally regenerative electrochemical cycle relationship, allowing for their ¾ of an inch battery to be charged at a high temperature and ability to deliver the energy at a lower temperature. This is a breakthrough, as the team was earlier able to harvest heat energy between 60°C and 100°C. The only downside to this charging technology is the very thing it harnesses, temperature. The idea is that the battery would cool down when removed from the pocket; if the room temperature matches body temperature, the charging method becomes less efficient.

Currently, their prototype can achieve a heat to electricity conversion rate of a mere 2%. It’s Dr Chen’s hope that they can increase that rate to 12%.

‘Tremendous low-grade heat is stored in industrial processes and the environment. Efficient and low-cost utilization of the low-grade heat is critical to imminent energy and environmental challenges.The upper limit of efficiency for harvesting heat is proportional to the temperature difference between hot source and cold source - room temperature. For low temperature heat sources, this temperature difference is small, so that upper limit of efficiency is already low. It takes some temperature difference to transfer heat into the heat engines, which further reduces the temperature range the heat engine works.’

The Tesla Model S might be the headline-grabber of the electric vehicle world, but the Nissan Leaf is the segment’s secret star. With over 130,000 sold worldwide since its introduction and record US sales in 2014, the little hatchback has helped its parents at the Renault-Nissan Alliance to sell over 200,000 EVs since 2010.

With that much success in the EV business, there’s no reason for the automaker to stop now, and according to CEO Carlos Ghosn a huge technological breakthrough is on the way to make plug-ins an attractive choice for more drivers than ever before. In an interview on Japanese TV, Ghosn confirmed that Nissan has a new battery that could allow for over 400 kilometers (249 miles) of range.

New batteries could “very soon take the issue of range off of the table.” - Jeff Kuhlman Ghosn was tight-lipped on the details of the tech, but Daily Kanban dug deeper. An unnamed Nissan engineer confirmed that the roughly 250-mile range would be for a Leaf-sized vehicle - a massive leap over the hatchback’s current EPA-rated max of 84 miles or 124 miles in Europe. The battery reportedly offers twice the capacity, while bringing weight and costs down compared to the present version. “Commercial applications could be no more than one model cycle away,” said the anonymous worker, making the innovation sound even more tantalizing.

Lending even more credence to this major battery innovation, Nissan spokesperson Jeff Kuhlman told Daily Kanban: “We continue our R&D efforts because we believe that we can do more with battery electric, and very soon take the issue of range off of the table.”

Renault-Nissan is betting a huge portion of its chips on the future of battery electric vehicles. The company even tried stuffing a 48-kilowatt hour pack into a Leaf for an event in Spain last year. While not its primary focus, the automaker is hedging its bets slightly by working with Daimler and Ford on fuel cell innovations, as well.
