#Imprint Energy is developing flexible, printed batteries for wearable devices Ultrathin zinc-polymer battery. Imprint Energy is developing flexible,
The California startup has been testing its ultrathin zinc-polymer batteries in wrist-worn devices and hopes to sell them to manufacturers of wearable electronics, medical devices, smart labels,
The company s approach is meant to make the batteries safe for on-body applications, while their small size and flexibility will allow for product designs that would have been impossible with bulkier lithium-based batteries.
Even in small formats the batteries can deliver enough current for low-power wireless communications sensors, distinguishing them from other types of thin batteries.
The company recently secured $6 million in funding from Phoenix Venture Partners, as well as AME Cloud Ventures, the venture fund of Yahoo cofounder Jerry Yang, to further develop its proprietary chemistry and finance the batteries commercial launch.
Previous investors have included CIA-backed venture firm In-Q-Tel and Dow chemical. The batteries are based on research that company cofounder Christine Ho began as a graduate student at the University of California, Berkeley,
where she collaborated with a researcher in Japan to produce microscopic zinc batteries using a 3-D printer.
The batteries that power most laptops and smartphones contain lithium which is highly reactive and has to be protected in ways that add size and bulk.
While zinc is more stable, the water-based electrolytes in conventional zinc batteries cause zinc to form dendrites,
branch-like structures that can grow from one electrode to the other, shorting the battery.
Ho developed a solid polymer electrolyte that avoids this problem, and also provides greater stability,
and greater capacity for recharging. Brooks Kincaid, the company s cofounder and president, says the batteries combine the best features of thin-film lithium batteries and printed batteries.
Such thin-film batteries tend to be rechargeable but they contain the reactive element, have limited capacity,
and are expensive to manufacture. Printed batteries are nonrechargeable, but they are cheap to make, typically use zinc,
and offer higher capacity. Working with zinc has afforded the company manufacturing advantages. Because of zinc s environmental stability, the company did need not the protective equipment required to make oxygen-sensitive lithium batteries.
One is batteries and one is displays, says Steven Holmes, vice president of the New Devices Group and general manager of the Smart Device Innovation team at Intel.
and began benchmarking its batteries against commercial batteries that claimed to be flexible. Existing batteries failed catastrophically after fewer than 1, 000 bending cycles,
she says, while Imprint s batteries remained stable. Imprint has also been in talks about the use of its batteries in clothes andweird parts of your body like your eye
Ho says. The company also recently began working on a project funded by the U s. military to make batteries for sensors that would monitor the health status of soldiers.
Other potential applications include powering smart labels with sensors for tracking food and packages. Via Technology Review Share Thissubscribedel. icio. usfacebookredditstumbleupontechnorat t

#Electric car travels over 1, 100 miles without a recharge on a new aluminum-air battery Together the Israeli company, Phinergy,
#The Phinergy aluminum-air battery at 100 kilograms (220 pounds) weight contained enough on board energy to allow the vehicle to travel up to 3, 000 kilometers (over 1, 860 miles.
Compare that to the best, current lithium-ion batteries in the Tesla Model S sedan.
and the on board battery weighs 5 times as much. How does an aluminum-air battery work?
They use an air-electrode capable of breathing ambient air and extracting the oxygen from it.
Compare this to traditional batteries which store and release oxygen from chemicals contained in a liquied or solid cathode.
An air battery doesn need t to replace or recharge its cathode. And an air battery is far lighter.
The combination means significantly more power for a longer period of time. Phinergy batteries use a porous electrode with a large surface area that captures the oxygen from ambient air.
The electrode also contains a silver-based catalyst that doesn t let CO2 interact with it.
To make the aluminum-air battery even more economical they are produced in areas where electrical energy capacity
In the case of the demonstration EV this week, the battery was forged at the Alcoa smelter in Baie-Comeau,
Aluminum-air batteries do break down over time. As they drain the metal turns into aluminum hydroxide.
When spent the entire battery can be recycled to forge new aluminum-air batteries. For the air-battery operator it will mean swapping out the old battery for a new one every few months.
This could be done at service centres which would keep an inventory of these batteries in supply.
Tesla#demonstrated its plans#for charging and swap out service centres back in July of last year.
In the Tesla demo the battery was swapped out in 90 seconds. So this notion of a quick battery replacement service that is as fast as refilling a conventional gas
or diesel tank seems very doable. In the case of the test car demonstrated at the#Canadian International Aluminum Conference#on Wednesday in Montreal,
but when used for longer trips the aluminum-air battery would kick in. To feed the chemical reaction from the aluminum-air battery drivers using a test car like this would add tap water every month
or two to feed the chemical reaction. Phinergy is also experimenting with other metal-air technologies.
A battery can last thousands of hours without chemical deterioration. The company hopes to see metal-air batteries made with aluminum
and runs on a rechargeable lithium-ion battery and offers about 8 hours of continuous use.
In the human arm of the research, the scientists gave a whole battery of cognitive tests to over 700 people with and without the gene variant.
#Japanese startup unveils a long-lasting and safer dual-carbon battery A young Japanese startup called Power Japan Plus,
or PJP, has a new type of battery under development that lasts longer, is safer,
and the cathode portion of the battery and hopes to start producing it later this year.
A battery is made up of an anode on one side and a cathode on the other, with an electrolyte in between.
While lithium ion batteries are the dominant batteries these days for laptops, cell phones and early electric cars,
For example, the batteries degrade pretty quickly over time (which explains why your laptop battery dies every couple of years),
and they can catch on fire under extreme impact. Theye also relatively expensive if you need a bunch of them to power an electric car,
An all-carbon battery A battery that uses carbon for both the anode and the cathode could be safer than a lithium ion battery
While battery fires have been rare for electric car companies, Tesla, GM and others have seen all a handful of cars with punctured batteries catch on fire,
and have faced PR hiccups as a result. Thermal runaway intense, long-lasting fires caused by lithium oxide catching on fire has long been the Achillesheel of lithium ion batteries.
A carbon battery also doesn degrade as quickly as a lithium ion battery over time. While a standard lithium ion battery with a two-year lifetime could have around 500 cycles of charging and discharging
Power Japan Plusdual-carbon battery could last for 3, 000 cycles, the company executives told me in a phone call.
their battery can charge 20 times faster than a standard lithium ion battery. Because the battery only uses carbon for its main active material,
it could cost less than standard lithium ion batteries, though executives declined to name its price. Lithium ion batteries have continued to drop in price
Finally, an all-carbon battery could be recycled more easily at the end of life than a lithium ion battery because it doesn contain rare earth materials and metals.
The idea for a dual carbon battery has been under development by Japanese researchers since the 1970s.
and material breakthroughs in the laboratory of applied chemistry professor Tatsumi Ishihara that could raise the capacity (how much electric charge can be delivered at a certain voltage) of those early dual carbon batteries.
While neither Kani or Nishina has a long background with battery chemistry (they hail from the telecom
and software sectors theye brought on Japanese battery cathode expert Kaname Takeya, who developed the cathode tech used today in the Toyota prius
and previously also worked on some battery startups including Quallion and Enerdel. Other companies are looking at ways to engineer carbon to make batteries better.
Energ2 is one of those startups, and the company has developed carbon materials for a variety of battery applications.
Because Power Japan Plusinnovation is in the development of the carbon material the company is also looking into a side business of selling its carbon to third parties.
could prove to be difficult for an early stage battery manufacturer, given all of the battery startups that have struggled over the years.
It a difficult market because scaling up battery production can take a long time and potentially, a lot of money.
Power Japan Plus says it is less capital-intensive than other battery companies because its battery can be manufactured on existing battery production lines.
Because the batteries don use rare materials and have only one active material, execs say the supply chain is extremely simple,
which also reduces costs. Additionally, executives told me that while they want to do some early pilot line production themselves,
if they want to scale up production to offer batteries to electric cars. Power Japan Plus intends to first launch batteries for the medical device and satellite industries,
which are focused hyper on safety. Later down the road, they could try to tackle electric cars.
An electric car with a battery pack of dual-carbon batteries could charge much faster and last much longer on the road, giving it a higher resale value.
Currently the team is supplying batteries for a Go-cart in a transportation proof-of-concept partnership.
In the immediate future, electric cars at least from dominant players Tesla and Nissan are betting on lithium ion chemistry for batteries.
When Tesla suddenly ran into a very public problem with its batteries, it installed Semantria in minutes
and other components needed for tiny lithium-ion batteries. Other projects include printed sensors fabricated on plastic patches that athletes could one day wear to detect concussions and measure violent impacts.
while fossil fuel-or battery-powered unmanned aircraft are expensive to run and possess a shorter range.
and onboard battery storage that allows the planes to fly at night. The drones are huge aircraft the smaller model,
Also since lithium-ion battery costs have dropped, electric car prices have dropped also, meaning that there are now several electric cars with price tags around $30, 000.
#Israeli startup Storedot charges smartphone batteries to full in 30 seconds Storedot It possible that youl be able to plug the smartphone in
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.

which have so far been held back by limited battery lives. he idea of eliminating cables would allow us to redesign things in ways that we haven yet thought of,
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.
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.
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.
if you look beyond just batteries, Tesla factory could be the largest factory of any kind,
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
which has never been much of a battery manufacturing powerhouse. No doubt, all of the states in the running including Arizona, Nevada,
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.
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,
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

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

#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,
90 percent of the lead recovered from the recycling of old batteries is used to produce new batteries,
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.
