#Graphene ribbons improve lithium ion batteries Anodes for lithium ion batteries built with ribbons of graphene perform better, tests show.
After 50 charge-discharge cycles, the proof-of-concept units retained a capacity that was still more than double that of the graphite currently used for LI battery anodes.
One area ripe for improvement is the humble battery. In an increasingly mobile world battery capacity is becoming a bottleneck that generally limits devices to less than a day worth of use.
In the new experiments, the Rice lab mixed graphene nanoribbons and tin oxide particles about 10 nanometers wide in a slurry with a cellulose gum binder and a bit of water, spread it on a current collector
and encased it in a button-style battery. GNRS are a single atom thick and thousands of times longer than they are wide.

#Imprint Energy is developing flexible, printed batteries for wearable devices Ultrathin zinc-polymer battery. Imprint Energy is developing flexible,
rechargeable batteries that can be printed cheaply on commonly used industrial screen printers. 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, and environmental sensors.
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.
When we talk about the things that constrain us in terms of the development of new products, there s really two that
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.
This unique and proprietary catalyst solves a common problem in air-battery technology carbonization caused by CO2 permeating the electrode.
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,
it was outfitted with both an aluminum-air and lithium-ion battery system. The notion behind this was that the EV could run on its lithium-ion charge
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.
They have developed a zinc-air battery that has some advantages over aluminum. Zinc-air is extremely durable.

#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,
charges faster and is less expensive than a standard lithium ion battery. The year-old company uses carbon for both the anode
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.
In a lithium ion battery lithium ions travel from the anode to the cathode through the electrolyte, creating a chemical reaction that allows electrons to be harvested along the way.
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.
They also say that because of the carbon chemistry, 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 and Tesla says it reducing the cost by 30 percent with its planned battery factory.
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.
Activated carbon can come from a variety of low cost, easily-available sources. The idea for a dual carbon battery has been under development by Japanese researchers since the 1970s.
Around six or seven years ago, scientists at Kyushu University started working on nanotechnology 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.
Now Power Japan Plus co-founded by Japanese tech entrepreneurs Dou Kani (the CEO and president) and Hiroaki Nishina (the COO) is looking to commercialize the research done at Kyushu.
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 the Tesla Model S. Takeya splits his time between San francisco and Japan and is the company CTO and CEO of its U s. operations.
He just finished a project for Argonne National Labs, 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.
Early stage While the tech has been under development for several years, the founders incorporated just a year ago,
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.
But big corporations that are interested in ultimately owning or licensing advanced battery tech might still be interested in providing early funding.
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,
they know they need a large manufacturing partner 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.
But farther down the line, other types of chemistries will need to be investigated to provide power for the next generation of electric cars h
