7X More Energy Designed From New Lithium-Ion Battery Stores
For many years,nickel-cadmium had been the only suitable battery for portable equipment from wireless communications to mobile computing.Nickel-metal-hydride and lithium-ion emerged In the early 1990s,fighting nose-to-nose to gain customer's acceptance.Today,lithium-ion is the fastest growing and most promising battery chemistry.Clean technologies increasingly depend on batteries,particularly lithium-ion battery.Everything from electric cars to renewable energy back-up storage,as well as almost all of our gadgets like smartphones and laptops use them.
In this new design,lithium ions flow from the cathode through the electrolyte,diffuse through the carbon shells,and enter the silicon-which can hold ten times as many lithium ions as carbon alone."The coolest part of this new system is that the silicon nanoparticles swell when filled with the lithium ions,but don't burst the carbon shell.The researchers say this new system is not only higher performing,but the manufacturing process to make these batteries is affordable,efficient and easily scaled up for higher production.
The energy density of lithium 18650 battery is typically twice that of the standard nickel-cadmium.There is potential for higher energy densities.The load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge.The high cell voltage of 3.6 volts allows battery pack designs with only one cell.Most of today's mobile phones run on a single cell.A nickel-based pack would require three 1.2-volt cells connected in series.Lithium-ion is a low maintenance battery,an advantage that most other chemistries cannot claim.There is no memory and no scheduled cycling is required to prolong the battery's life.In addition,the self-discharge is less than half compared to nickel-cadmium,making lithium-ion well suited for modern fuel gauge applications.
To really push these technologies forward,battery storage and performance has to increase without increasing in size.EMSL explains, "When in use,lithium ions flow from the cathode through an electrolyte into the anode,most commonly made of carbon.During recharging,the ions are pushed back to the cathode where they started.Researchers built upon current technology by making a new type of anode that consists of single silicon nanoparticles inside carbon shells,much like yolks inside eggs.
Researchers at the Environmental Molecular Sciences Laboratory (EMSL) think they've come up with a novel way to do just that by using silicon nanoparticles that swell to increase the amount of lithium ions that can be stored,resulting in lithium batteries system that can store seven times more energy and be discharged and recharged five times as many times as the current technology.This advance could lead to batteries that not only store much more energy,letting electronics run longer on a single charge,but batteries that have much longer lifetimes.

Researchers Eye Lithium Ion Battery Breakthrough Technology
A new lithium ion battery technology capable of operating at extreme temperatures without requiring thermal management was unveiled by A123 Systems this week.Nanophosphate EXT is designed to significantly reduce or eliminate the need for heating or cooling systems,which is expected to create sizeable new opportunities within the transportation and telecommunications markets,among others.
Researchers from Northwestern University are working on developing a super-battery that can keep a cellphone charged for a week and be recharged in just 15 minutes.However,making small electronics a little more convenient is only the beginning of their ambition,as the researchers believe the technology also might make for far more efficient and smaller electric car batteries.According to the university,the breakthrough in developing lithium battery that can hold a charge 10 times longer than current batteries has come by addressing both energy capacity and charge rate.
The capacity was jacked up by sandwiching clusters of lithium-accomodating silicon between the graphene sheets of the anode."This allowed for a greater number of lithium atoms in the electrode while utilizing the flexibility of graphene sheets to accommodate the volume changes of silicon during use,"the researchers explained.Then,to speed up charge rate,the team used a chemical oxidation process to create "in-plane defects,"which is a fancy way of saying tiny holes (really tiny;like,10 to 20 nanometers wide).These gave the lithium ions a shortcut,the university said,into the anode,where they could be stored by reaction with silicon.But don't pull out your wallet to buy the batteries just yet.
Researchers say the technology is still anywhere from three to five years from being on the market."We have found a way to extend a new lithium batteries charge life by 10 times," said Harold H. Kung,lead author of the paper."Even after 150 charges,which would be one year or more of operation,the battery is still five times more effective than lithium-ion batteries on the market today."Unlike lead acid or other advanced battery technologies,it is designed to maintain long cycle life at extreme high temperatures and deliver high power at extreme low temperatures.
According to the testing performed to date at the Ohio State University's Center for Automotive Research (CAR) and the very low observed rate of aging,cells built with A123's Nanophosphate EXT are expected to be capable of retaining more than 90 percent of initial capacity after 2,000 full charge-discharge cycles at 45 degrees Celsius.CAR has also starting testing the cold temperature performance of the technology,which A123 expects will deliver a 20 percent increase in power at temperatures as low as minus 30 degrees Celsius.
Dr.Yann Guezennec,senior fellow at CAR and professor of mechanical engineering at the Ohio State University said,"If our testing also validates the low-temperature power capabilities that A123's data is showing,we believe Nanophosphate EXT could be a game-changing primary battery breakthrough for the electrification of transportation,including the emerging micro hybrid vehicle segment.""By delivering high power,energy and cycle life capabilities over a wider temperature range,we believe Nanophosphate EXT can reduce or even eliminate the need for costly thermal management systems," said David Vieau,CEO of A123 Systems.

New Cellphone Battery Technology Make Battery Longer Life
IPhone 4S owners bemoaning their feeble battery life may have some hope,at least,for the future:Northwestern University engineers have developed a cellphone battery that charges in 15 minutes and stays charged for more than a week.They've created an electrode for lithium battery that allows the batteries to hold a charge up to 10 times greater than current technology and charge 10 times faster.
As well as better batteries for cellphones and iPods,the technology could lead to more efficient,smaller batteries for electric cars,says the team.The technology could hit the market in the next three to five years."Even after 150 charges,which would be one year or more of operation,the battery is still five times more effective than lithium-ion batteries on the market today,"says lead author Harold H Kung.
Lithium-ion batteries charge through a chemical reaction in which lithium ions are sent between two ends of the battery,the anode and the cathode.As energy in the battery is used,the lithium ions travel from the anode,through the electrolyte,and to the cathode; as the battery is recharged,they travel in the reverse direction.With current technology,the performance of a lithium-ion battery chargers is limited.How long a battery can maintain its chargeis limited by how many lithium ions can be packed into the anode or cathode.Meanwhile,the speed at which it recharges is limited by the speed at which the lithium ions can make their way from the electrolyte into the anode.
"Now we almost have the best of both worlds,"Kung said."We have much higher energy density because of the silicon,and the sandwiching reduces the capacity loss caused by the silicon expanding and contracting.Even if the silicon clusters break up,the silicon won't be lost.The team also used a chemical oxidation process to create miniscule holes in the graphene sheets to give the lithium ions a 'shortcut' into the anode.This reduces the time it takes the battery to recharge by up to 10 times.
In current rechargeable batteries,the anode-made of layers of carbon-based graphene sheets-can only accommodate one lithium atom for every six carbon atoms.Replacing the carbon with silicon means much more lithium can be accommodated.However,silicon expands and contracts dramatically in the charging process,causing fragmentation and losing its charge capacity rapidly.Kung's research team has been able to stabilize the silicon in order to maintain maximum charge capacity,by sandwiching clusters of silicon between the graphene sheets.This allows for a greater number of lithium atoms in the electrode while utilizing the flexibility of graphene sheets to accommodate the volume changes of silicon during use.

New Lithium Batteries Will RunTen Times Longer and Charge Faster
While gadgets improve by leaps and bounds every year,the technology that powers them hasn't.Batteries still suck,unless something comes of this research at Northwestern University that promises new lithium-ion alternatives that charge ten times faster with ten times the capacity.The lithium batteries based on the new technology may come to the market within three to five years.In future,mobile phone batteries could hold ten times more charge than the current lot of handsets.Researchers of Northwestern University,USA,have invented the new Li-ion battery,which they say would help future mobile phones to get charged faster than today's handsets.
"We have found a way to extend a new lithium-ion battery's charge life by 10 times,"said Harold H Kung,a member of the research team and the lead author of the research paper."Even after 150 charges,which would be one year or more of operation,the battery will be five times more effective than lithium-ion batteries available in the market today," Kung added.Actually,there are numerous graphene layers in Li-ion batteries,which are filled by Lithium ions.So when users charge these batteries,atoms move towards the edge of the sheet to make room for more ions.The speed of recharging becomes less if these ions cannot quickly go from layer to layer.
Inside a battery,lithium ions travel between an anode and a cathode,passing through an electrolyte in the process.During charging,the speed at which those ions can get from the electrolyte to the anode affects how quickly a battery can be replenished.The ions have to pass between layers of thin graphene sheets,but in order to do so they must travel all the way to the edges first.This ends up creating mini ionic traffic jams,slowing down the charging process.So to improve this,the engineers used a chemical oxidation process to punch miniscule holes in the graphene sheets,essentially giving lithium battery a shortcut to the anode.
The same technique was adopted by the Northwestern University researchers.They populated the area between two graphene sheets in Li-ion battery with Silicon nanoclusters.In this manner,the number of ions that can live in the battery increases greatly-as a result,the charge capacity is improved greatly.The research lab took the process one step further by making perforations in the graphene sheets,which made sure the ions found a shortcut to the next layer much more easily.The researchers say the technology may make its way to the market within three to five years.
To increase the capacity of a ni-mh battery,the team also sandwiched clusters of silicon between those graphene sheets.In a traditional battery carbon is used,which can only accommodate one lithium atom for every six carbon atoms. But for every silicon atom, four lithium atoms can be accommodated,which drastically increases a battery's capacity.And by sandwiching the silicon between the flexible graphene sheets,they also found a way to deal with silicon's tendency to expand and contract which has traditionally made it impractical for use in batteries.
