Flakey New “Foam Party” Graphene Battery Breakthrough

Boy, does this look like fun. You got your flakes, your foam, your sheets of Kapton plastic, your laser, and you wake up in the morning with a hangover and a new type of super graphene battery. This interesting mashup comes to us by way of that dynamic duo of graphene, Rice University and the US Air Force (more on that later), so you know it’s got to be good.

For those of you new to the graphene topic, before we discovered nanocellulose fibers we were calling graphene the nanomaterial of the new millennium. Graphene is a sheet of carbon only one atom thick. This nano-slim frame provides it with exceptional strength and conductivity, dovetailing perfectly with new clean technology.

The problem is how to actually use something that is only one atom thick, and that’s where the graphene battery — the graphene supercapacitor, to be more precise — comes in.

The Rice University Graphene Battery

A supercapacitor is a type of battery that charges and discharges rapidly, so we’re going to just simplify things by calling it a battery most of the time.

The Rice team made their new graphene microsupercapacitor (same thing as a supercapacitor but smaller) using a process they call LIG, for laser induced graphene.

They solved the first problem — how to use something that is only one atom thick — by creating their graphene battery on a base of plastic film. That took some doing, as it turned out that not all plastic film is equal when it comes to graphene batteries.

They finally nailed it when they got to polyimide, a heat-resistant plastic film that’s been around for about 50 years or so.

The rest of the setup is relatively simple. Instead of trying to layer single-atom sheets of graphene onto the plastic, the team applied a porous foam of graphene flakes.

New Lithium-Ion Battery Discovery Contradicts Everything You Thought You Knew

Researchers over at Lawrence Berkeley National Laboratory have made a new lithium-ion battery discovery that could prove a little disconcerting to a lot of folks in the energy storage field. The finding comes out of a first-of-its-kind analysis using X-ray absorption spectroscopy, and apparently it contradicts “numerous” studies aimed at improving the efficiency of lithium-ion batteries.

The good news is, the new lithium-ion battery discovery could accelerate the development of next-generation EV batteries, so let’s see what all the buzz is about.

The new lithium-ion battery research focused on unlocking some of the mystery behind the nanoscale function of the liquid electrolyte in lithium-ion batteries. For those of you new to the battery topic, the electrolyte is the stuff that enables an electrical charge to flow from the battery to whatever device you want to electrify, so yeah, the electrolyte is pretty important.

The electrolyte commonly used in lithium-ion batteries consists of a lithium salt dissolved in a solvent, typically based on an alkyl carbonate. Here’s the deal according to study co-author Richard SayKally of Berkeley Lab:

There’s disagreement in the battery industry on the nature of the local solvation environment of lithium ions in these solutions, a critical issue because the desolvation of the ions as they move through the negative electrode is believed to limit the electrical power that can be made available.

A Prototype Battery Could Double the Range of Electric Cars

An experimental lithium-ion battery based on materials developed at a U.S. Department of Energy lab stores twice as much energy as the batteries used in most electric cars.

If the technology can be commercialized, it could give affordable electric cars a range of over 200 miles per charge, says Hal Zarem, CEO of Seeo, a startup that’s working on the technology. Today the cheapest electric cars, which cost around $30,000, typically have a range of less than 100 miles.

Alternatively, the improved storage capacity could be used to cut the size of battery packs in half while maintaining the current driving range, making electric vehicles considerably cheaper. A conventional battery pack with a range of 100 miles costs roughly $10,000.

Seeo, which is based in Hayward, California, recently raised $17 million from investors, including Samsung Ventures. It plans to start shipping batteries to potential customers for evaluation next year.

Graphene Could Kill Lithium-Ion Batteries

Don’t break out the widow’s weeds just yet, but it looks like momentum is building for energy storage to move past the lithium-ion phase and get into the more powerful territory of lithium-sulfur technology. In the latest development, a multinational research team has figured out how to overcome a major obstacle in the path of lithium-sulfur energy storage, by using graphene as a “bridge” between different components.

In theory, lithium sulfur (Li-S) batteries possess far greater energy density than the familiar lithium-ion (Li-ion), so breaking the technology out of the lab and into commercial development could have huge clean tech implications for EV battery range and energy storage for solar and wind sources, among other applications.

Tesla Begins Battery Swap Pilot Program in California

Faster or free? That was the question posed by Tesla CEO Elon Musk last year when he unveiled the company’s battery swap technology that, he claims, is faster than topping up a conventional premium saloon’s fuel tank.

Model S owners currently have the option of stopping at one of Tesla’s 312 stations and use one of the 1,748 Superchargers available to charge their vehicles’ battery. The only problem is that they have to wait for an hour to obtain a 400-mile (640 km) range, which may not be convenient.

Therefore Tesla has developed a scheme in which the driver will stop at a station and simply replace the EV’s depleted battery back for a fully charged one. This takes three minutes, or less than the time needed to top-up a premium saloon’s fuel tank with gas. Musk said that this is due to the time needed to remove the titanium and aluminum plates that shield the battery, otherwise it would take just a minute and it’s something the company is working on.

For the time being, Tesla is initiating a pilot program with invited Model S owners, who will be able to swap the battery at a custom-built station across the street from Tesla Superchargers at Harris Ranch, California.

The nag is that a. they will have to make an appointment and b. pay a fee, which Musk says will be “slightly less” than the cost of filling up a gas-powered premium saloon’s fuel tank.

What Will the Battery Market Look Like in 2030?

New Years is a good time for individuals to look to ahead and to wonder a bit about what the future holds them. The same is true for companies and for entire industries.

Earlier this past year at the Battery Show, Christophe Pillot of Avicenne Energy made a presentation about the state of the worldwide battery market in 2013. One of the slides in Mr. Pillot’s presentation was a bar graph breaking down the battery market into its largest individual components. The largest component shown on Mr. Pillot’s slide, of course, was SLI batteries followed by portable batteries. Other automotive batteries came next, followed by a large number of industrial and stationary battery applications in increasingly smaller sizes accounting for the balance of the market. Certain applications that generated a lot of attention this year, such as residential and grid ESS, were so small as to be barely perceptible on Mr. Pillot’s graph.

The interesting question to ponder in the New Year is what will Mr. Pillot’s graph look like 10 or 15 years from now? How is the industry going to change? And perhaps, more interestingly, what significant bars will appear on Mr. Pillot’s graph in 2030 that we do not even anticipate today?

As to the question of how the industry is going to change, the balance of Mr. Pillot himself made several interesting predictions. Mr. Pillot suggests that by 2025, lead acid batteries, including SLI batteries, will still represent the largest share of the market. During the 2012-2020 period, however, Mr. Pillot expects the market for lead acid batteries to grow at a 4% CAGR. Lithium-ion batteries and the applications they serve will grow, according to Mr. Pillot, at a 16% CAGR. Mr. Pillot predicts that by 2020, the lithium-ion battery market, powered by the growth of the xEV and ESS applications, will be more than half the size of the market for lead acid batteries.

This is all very interesting. But what about the bars that will appear on Mr. Pillot’s graph in 2030 that do not even appear on his graph for 2013? Is there a “killer app” that will emerge in the next 15 years that could fundamentally impact the market for batteries? After all, would xEV’s, ESS, and notebook and tablet computers have even appeared on Mr. Pillot’s graph in 2000?

It is not difficult to speculate on what some of the new “killer apps” for batteries might be by 2030. Robotics, control systems, advanced weaponry, and wearable consumer goods are all possibilities. If we have learned anything over the last 15 years, it is that the battery market is dynamic and the greatest limit on that market is not technology but imagination.

At the NAATBatt 2015 Annual Meeting & Conference next February in Phoenix, we will take a serious look at one of the new battery technologies that may well drive some of these “killer apps” and perhaps emerge as a significant bar on Mr. Pillot’s slide for the battery market in 2030: thin film battery technology.

What will the battery market look like in 2030? If it exists at all, it will mostl likely look a lot like the lead-acid batteries in your car Graeme. Kind of skanky and dusty. :razz:

As usual you can't read.

This brings us back to the missing bars on Mr. Pillot’s future slide showing the composition of the battery industry in 2030. My bet is that one of the most significant bars on that graph, which is entirely missing on the graph for 2013, will be the thin film batteries that power what some pundit already refer to as the “internet of everything”: the interconnection of almost all devices and consumer products to each other. If my guess is right, this will be a huge opportunity for the battery industry as a whole. I hope you will join us in Phoenix next February and learn more about it.

An extremely interesting bit of technology here http://www.gizmag.com/high-energy-density-supercapacitor/37075/

The hybrid supercapacitor is reportedly six times as energy-dense as a commercially available supercapacitor and packs nearly as much energy per unit volume as a lead-acid battery.

...

Like other supercapacitors, their device charges and discharges very quickly and lasts more than 10,000 recharge cycles. But, according the scientists, their invention also stores six times more energy than a conventional supercapacitor, holding more than twice as much charge as a typical thin-film lithium battery in one fifth the thickness of a sheet of paper.

...

Supercapacitors are usually stacked on top of each other and packaged into a single unit, but the researchers have been able to take advantage of the thinness of their device by integrating it inside a solar cell array. In this application, it was found that the supercapacitor could quickly store electrical charge generated by a solar cell during the day, hold the charge until evening, and then power an LED overnight.

This is just one of many potential uses for the technology.


But of course, the difficulty is getting from the lab to commercial production (see algae biofuels etc).
What we think, we become.

New “Designer” Energy Storage Breakthrough Packs 3 Football Fields Into 1 Ounce of Carbon

Lithium-ion technology is still the gold standard for energy storage as demonstrated by the popularity of the new Powerwall battery, Tesla Energy’s much-publicized foray into Li-ion energy storage for homes and businesses. However, some new technologies are sneaking up behind. In the latest development, lithium-sulfur batteries could benefit from a new “designer carbon” engineered by a team of researchers at Stanford University.

The new designer carbon material could have a variety of applications, but the Stanford University team has zeroed in on the energy storage potential, particularly in respect to lithium-sulfur (Li-S) batteries.

The new material is actually a synthetic form of bio-based activated carbon. For those of you new to the topic, activated carbon is a common material that shows up in water filters and deodorizers, among many other things — but not energy storage devices, at least not yet.


Here are a couple of snippets from the new study:

For example, raising the processing temperature from 750 degrees Fahrenheit (400 degrees Celsius) to 1,650 F (900 C) resulted in a 10-fold increase in pore volume.

Subsequent processing produced carbon material with a record-high surface area of 4,073 square meters per gram – the equivalent of three American football fields packed into an ounce of carbon. The maximum surface area achieved with conventional activated carbon is about 3,000 square meters per gram.

24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Stealth-mode battery start-up 24M has introduced its new semi-solid lithium-ion cell. Co-founded by MIT’s Dr. Yet-Ming Chiang, 24M’s Chief Scientist, the company is leveraging existing, preferred energy storage chemistry but using a new cell design with semi-solid (a mixture of solid and liquid phases) thick electrodes and manufacturing innovations to deliver what it says will be up to a 50% reduction in current Li-ion costs. (Dr. Chiang was also a co-founder of A123 Systems; 24M originated as an A123 spinout. Earlier post.)

Together, our inventions achieve what lithium-ion has yet to do—meet the ultra-low cost targets of the grid and transportation industries. By 2020 our battery costs will be less than $100 a kilowatt-hour (kWh). We’re emerging at the right time with the right technology,” said Throop Wilder, 24M CEO.

Until now, the energy storage field has had two options to try to drive down costs—high volume production or entirely new chemistries that may never move from the lab to the commercial floor. 24M says it is presenting a third option.

OS, Just saw this when I answered Tanada.

Even if battery-swap stations become abundant, fast-swapping as a source of revenue for Tesla may never be more profitable than the theoretical fast-swapping was when it earned Tesla many highly lucrative ZEV credits. Since Tesla only builds ZEVs, it has no need for the ZEV credits it earns. Instead, it sells them to other automakers that are either out of compliance or hedging against stricter regulations coming in the future. In 2013, Tesla reported revenue of $129.8 million from its sale of ZEV credits. Without that money, the company wouldn’t have turned a profit.

But CARB has since closed the fast-refueling loophole, and Tesla will have to document that its customers are actually using fast-swapping stations before the company can claim the extra credits. Analisa Bevan, chief of sustainable transportation technology at CARB, anticipates that Tesla will follow through with its swapping scheme even though the credit incentive for fast refueling disappears a­ltogether three years from now.
