according to a report by the Wall street journal. An Israeli startup by the name of Storedot revealed the technology at Microsoft Think Next Conference using standard smartphone batteries,

Fast battery chargers already exist, but theye expensive, unwieldy things for special batteries. Storedot, however, claims that its technology will only cost around twice as much as traditional chargers.

Batteries traditionally charge quickly during the first 80 percent of the charge, but slow to a trickle for the last 20 percent

so as not to overload the battery. Storedot has apparently found a way around this limitation,

and that itl even work with existing technology. Unfortunately, production won even begin until sometime in 2016.

#Tesla s plans for world s largest battery factory will be a game changer Tesla motors, the electric car maker, hasn blazed just its own trail

the battery. This week Tesla revealed more details about its plans to build a massive the largest of its kind in the world battery factory in the U s. that will produce enough lithium-ion batteries by 2020 to outfit 500,000 electric cars.

While Tesla only released a few details of the plan, the company said that by 2020 the battery cell output of the factory would be 35 gigawatt hours per year,

and battery pack output would be 50 gigawatt hours per year. Let put these production numbers in perspective.

As Tesla has said itself its cars are constrained by global battery production, and it would need to use all of the batteries produced for electric cars in 2013

(and then some) to make those 500,000 per year by 2020. According to Navigant Research analyst Sam Jaffe, Tesla already used half of all the batteries made for electric cars in the world in 2013 for its Model S car (22,477 cars sold.

In terms of global lithium ion and advanced battery production beyond just for electric cars Tesla so-called igafactoryis still massive;

it jaw-dropping actually. According to Navigant figures, battery factories in the world produced close to 27 gigawatt hours of advanced batteries (the vast majority of these,

over 90 percent, are lithium-ion batteries) in 2012. The bulk of those batteries 23 gigawatt hours were for consumer electronics,

like our laptops and cell phones. Given Tesla production goals outline above, the planned factory would more than double the current entire world lithium ion battery production.

Of course, global lithium ion battery production would also ramp up outside of Tesla as well as more gadgets and cell phones are sold

and more devices get connected. And now if you look beyond just batteries, Tesla factory could be the largest factory of any kind,

anywhere in the world in terms of inputs in and outputs out, said Jaffe, though he notes that such a thing is pretty hard to measure.

The country that made the most advanced batteries in 2012 was produced China, which about 13 gigawatt hours of batteries.

Chinese batteries traditionally have been the cheapest in the world, but theye also been of lower quality compared to those made in Japan, Korea and the U s. However, battery expert and founder and CEO of battery startup GELI,

Ryan Wartena, told me that he seen the quality of Chinese batteries go up substantially over the past year.

Chinese battery giants also have been trying to boost production as well, and Chinese lithium battery manufacturer Thunder Sky Group had been looking to build a battery factory in Russia working with Russian state run agency RUSNANO this would have been the largest lithium ion battery factory in the world (I not sure of the current

status of this factory). The second largest producer of batteries in the world in 2012 was Japan, with about 7 gigawatt hours.

South korea follows with about 2 gigawatt hours. The U s. had about 1. 2 gigawatt hours

and that following the attempts of Obama stimulus package to boost battery production in the U s. through companies like A123 Systems and LG Chem.

So as you can see, Tesla plans to generate 35 and 50 gigawatt hours per year in cells and packs, just in the U s,

. all of a sudden tilts the world lithium ion battery production in favor of the U s.,which has never been much of a battery manufacturing powerhouse.

No doubt, all of the states in the running including Arizona, Nevada, Texas and New mexico will be vying for those 6, 500 jobs.

Tesla factory will also be a competitive threat to Chinese battery production dominance and will help lower the overall price of lithium ion batteries globally. ust the threat of (Tesla CEO) Elon musk building this huge factory will lower prices,

says Wartena, as the companies will be willing to lower their margins to compete. Like Tesla has done with many of its strategies

it taking a novel approach to working with partners to build the battery factory. Tesla is selling debt (convertible senior notes) to the tune of between $1. 6 billion to $1. 8 billion to fund part of the battery factory,

but Tesla said its partners will likely poney up the extra $2 billion to $3 billion (though,

it could be even higher). Panasonic is Tesla chief battery supplier, but in recent months Tesla has also beentalking with Samsung SDI for batteries.

Traditionally auto makers have multiple suppliers for core components so that they can get the best price and use the other suppliers as leverage.

It should be noted that Tesla hasn confirmed that Panasonic is the battery supplier partner for the planned factory.

Musk even told Bloomberg that the Panasonic deal wasn done 100 percent. Essentially Tesla is keeping its options open for other suppliers to come in

and it using an unusual way of working with Panasonic. Navigant Jaffe called the method unique combination of carrot and stick.

Tesla said that it intends to use some of the battery output for stationary energy storage, which means batteries used for buildings, the grid and even homes.

As wee reported before, Tesla and solar financier and installer Solarcity (Musk other energy company) have been quietly selling small volumes of Tesla batteries as energy storage paired with Solarcity solar projects.

If Tesla is able to reduce the cost of lithium ion batteries by a third with its new factory,

it could make energy grid storage much more economical. Batteries for the grid at current prices are largely too expensive for most projects.

There a handful of companies that are trying to innovate around using batteries for grid storage

but if Tesla could get the battery price low enough it can potentially disrupt grid storage, too.

Lower-cost lithium-ion batteries could make clean energy much more viable. Pairing battery farms with wind and solar panel farms would enable clean power to store energy

when the wind stops blowing and the sun goes down. The end goal for Tesla is that cheap batteries could help Tesla deliver its $35, 000 third generation electric car.

It might not be able to get to that price with battery cost reductions alone, but it gets Tesla a whole lot closer t

#Imergy Power systems develops high-performance flow batteries Imergy Power systems has achieved a milestone in energy storage by developing a process for producing high-performance flow batteries with recycled vanadium from mining slag oil field sludge fly ash and other forms of environmental waste.

Other manufacturers of vanadium flow batteries build their devices with virgin vanadium extracted from mining. It must then be processed to a 99%plus level of purity.

Through an extensive R&d program, Imergy has developed a way to produce flow batteries with vanadium at a 98%purity level that can be harvested from environmental waste sites.

and processing vanadiumhe principal active ingredient in many flow battery electrolytesy 40%relative to competitors. As a result of this technology and other developments, Imergy will be able to lower the cost of its flow batteries from $500 a kilowatt hour, already an industry benchmark, to under $300 per kilowatt hour.

Imergy flow batteries from low-grade vanadium will also be capable of storing more energy per kilogram than conventional vanadium flow batteries by more than twice, giving cell phone operators, solar power plant developers, microgrid owners

and other customers more flexibility and capacity for managing outages curbing peak power or reducing demand charges.

#Beating battery drain Stream video on your smartphone or use its GPS for an hour or two and you ll probably see the battery drain significantly.

As data rates climb and smartphones adopt more power-hungry features battery life has become a concern.

Now a technology developed by MIT spinout Eta Devices could help a phone s battery last perhaps twice as long

The primary culprit in smartphone battery drain is an inefficient power amplifier a component that is designed to push the radio signal out through the phones antennas.

This means smartphone batteries lose longevity and base stations waste energy and lose money. But Eta Devices has developed a chip (for smartphones)

You can look at our technology as a high-speed gearbox that every few nanoseconds modulates the amount of power that the power amplifier draws from the battery explains Joel Dawson Eta Devices chief technology officer

Dawson says this could potentially double current smartphone battery life. Besides battery life Dawson adds there are many ways the telecommunications industry can take advantage of improved efficiency.

Eta Devices approach could lead to smaller handset batteries for example and even smaller handsets since there would be less dissipating heat.

The technology could also drive down operating costs for base stations in the developing world where these stations rely on expensive diesel fuel for power

#Recycling old batteries into solar cells This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries a potential source of lead pollution into new,

Battery pileup ahead One motivation for using the lead in old car batteries is that battery technology is undergoing rapid change, with new, more efficient types, such as lithium-ion batteries,

swiftly taking over the market. nce the battery technology evolves, over 200 million lead-acid batteries will potentially be retired in the United states,

and that could cause a lot of environmental issues, Belcher says. Today, she says, 90 percent of the lead recovered from the recycling of old batteries is used to produce new batteries,

but over time the market for new lead-acid batteries is likely to decline, potentially leaving a large stockpile of lead with no obvious application.

In a finished solar panel, the lead-containing layer would be encapsulated fully by other materials, as many solar panels are today,

The team work clearly demonstrates that lead recovered from old batteries is just as good for the production of perovskite solar cells as freshly produced metal.

#New manufacturing approach slices lithium-ion battery cost in half An advanced manufacturing approach for lithium-ion batteries, developed by researchers at MIT and at a spinoff company called 24m,

promises to significantly slash the cost of the most widely used type of rechargeable batteries while also improving their performance

says Yet-Ming Chiang, the Kyocera Professor of Ceramics at MIT and a cofounder of 24m (and previously a cofounder of battery company A123).

The existing process for manufacturing lithium-ion batteries, he says, has changed hardly in the two decades

In this so-called low battery, the electrodes are suspensions of tiny particles carried by a liquid

and pumped through various compartments of the battery. The new battery design is a hybrid between flow batteries and conventional solid ones:

In this version, while the electrode material does not flow, it is composed of a similar semisolid, colloidal suspension of particles.

Chiang and Carter refer to this as a emisolid battery. impler manufacturing processthis approach greatly simplifies manufacturing,

and also makes batteries that are flexible and resistant to damage, says Chiang, who is senior author of a paper in the Journal of Power Sources analyzing the tradeoffs involved in choosing between solid

and flow-type batteries, depending on their particular applications and chemical components. This analysis demonstrates that

while a flow battery system is appropriate for battery chemistries with a low energy density (those that can only store a limited amount of energy for a given weight),

for high-energy density devices such as lithium-ion batteries, the extra complexity and components of a flow system would add unnecessary extra cost.

Almost immediately after publishing the earlier research on the flow battery, Chiang says, e realized that a better way to make use of this flowable electrode technology was to reinvent the lithium ion manufacturing process. nstead of the standard method of applying liquid coatings to a roll of backing material,

thicker electrodes, the system reduces the conventional battery architecture number of distinct layers, as well as the amount of nonfunctional material in the structure, by 80 percent.

Bendable and foldablein addition to streamlining manufacturing enough to cut battery costs by half, Chiang says,

the new system produces a battery that is more flexible and resilient. While conventional lithium-ion batteries are composed of brittle electrodes that can crack under stress

the new formulation produces battery cells that can be bent, folded or even penetrated by bullets without failing.

This should improve both safety and durability, he says. The company has made so far about 10,000 batteries on its prototype assembly lines, most

of which are undergoing testing by three industrial partners, including an oil company in Thailand and Japanese heavy-equipment manufacturer IHI Corp. The process has received eight patents

By 2020, Chiang estimates that 24m will be able to produce batteries for less than $100 per kilowatt-hour of capacity.

when is it better to build a flow battery versus a static model. This paper will serve as a key tool for making design choices

and go-no go decisions. iswanathan adds that 24m new battery design ould do the same sort of disruption to lithium ion batteries manufacturing as


newsoffice.mit.edu 2015 00779.txt.txt

one of their biggest limitations is the capacity of their tiny batteries to deliver enough power to transmit data.

At the moment, the coin-sized batteries used in many small electronic devices have limited very ability to deliver a lot of power at once,

Small batteries are suited generally poorly for such power needs, he adds. e know it a problem experienced by a number of companies in the health-monitoring

So an alternative is to go to a combination of a battery and a capacitor, Hunter says:

the battery for long-term, low-power functions, and the capacitor for short bursts of high power. Such a combination should be able to either increase the range of the device,

The new nanowire-based supercapacitor exceeds the performance of existing batteries, while occupying a very small volume. f youe got an Apple Watch and

because other energy storage technologies such as fuel cells, batteries, and flywheels tend to be less efficient, or simply too complex to be reduced practical
