but Jun Takada and colleagues at Okayama University discovered unexpected industrial functions of L-BIOX such as a great potential as an anode material in lithium-ion battery.
Since use of the battery that is a powerful electric source for portable electric devices has expanded to a variety of new areas such as transportation
and electric power storage improvement of battery capability and effort to develop new electrode materials have been demanded.
The general processes of nanosizing and appropriate surface modification which are required for tuning the battery property are complicated
Takada and colleagues proposed a unique approach to develop new electrode materials for Li-ion battery.

such as in batteries for portable devices, where reduced weight is also highly desirable. Another property of these materials is that they conduct sound and elastic waves very uniformly,
such as the fine structures of cell components or modern catalysts and batteries. Until now, such fine details could only be rendered visible with the aid of electron microscopes
Batteries in electric vehicles are responsible for a significant portion of the vehicle mass. And the size of batteries in portable electronics limits the trend of downsizing.
Silicon is a type of anode material that is receiving a lot of attention because its total charge capacity is 10 times higher than commercial graphite based lithium ion battery anodes.
Consider a packaged battery full-cell. Replacing the commonly used graphite anode with silicon anodes will potentially result in a 63 percent increase of total cell capacity and a battery that is 40 percent lighter and smaller.
In a paper Silicon Decorated Cone Shaped Carbon nanotube Clusters for Lithium ion battery Anode recently published in the journal Small UC Riverside researchers developed a novel structure of three-dimensional silicon decorated cone-shaped
carbon nanotube clusters architecture via chemical vapor deposition and inductively coupled plasma treatment. Lithium ion batteries based on this novel architecture demonstrate a high reversible capacity and excellent cycling stability.
space-consuming batteries could become a thing of the past. It is possible to further miniaturize the electronic devices
or the space that has been used previously for batteries could be used for other purposes. In the case of launch vehicles
such as a laptop whose casing serves as its battery, or an electric car powered by energy stored in its chassis,
instead of storing it in chemical reactions the way batteries do. As a result supercaps can charge
and operate for millions of cycles, instead of thousands of cycles like batteries. In a paper appearing online May 19 in the journal Nano Letters, Pint and Westover report that their new structural supercapacitor operates flawlessly in storing
One area where supercapacitors lag behind batteries is in electrical energy storage capability: Supercaps must be larger and heavier to store the same amount of energy as lithium-ion batteries.
However, the difference is not as important when considering multifunctional energy storage systems.""Battery performance metrics change when you're putting energy storage into heavy materials that are needed already for structural integrity,
"Supercapacitors store ten times less energy than current lithium-ion batteries, but they can last a thousand times longer.
Sandwiched between the two electrodes is a polymer film that acts as a reservoir of charged ions, similar to the role of electrolyte paste in a battery.
There have also been recent press reports of several major efforts to develop multifunctional materials or structural batteries for use in electric vehicles and for military applications.
#Silly Putty material inspires better batteries Using a material found in Silly Putty and surgical tubing, a group of researchers at the University of California,
Riverside Bourns College of Engineering have developed a new way to make lithium-ion batteries that will last three times longer between charges compared to the current industry standard.
The team created silicon dioxide (Sio2) nanotube anodes for lithium-ion batteries and found they had over three times as much energy storage capacity as the carbon-based anodes currently being used.
which are always trying to squeeze longer discharges out of batteries.""We are taking the same material used in kids'toys
and medical devices and even fast food and using it to create next generation battery materials, "said Zachary Favors,
The paper,"Stable Cycling of Sio2 Nanotubes as High-performance Anodes for Lithium-Ion Batteries,"was published online in the journal Nature Scientific Reports.
There key finding was that the silicon dioxide nanotubes are extremely stable in batteries, which is important
The device is a supercapacitor cousin to the battery. This one packs an interconnected network of graphene and carbon nanotubes so tightly that it stores energy comparable to some thin-film lithium batteriesn area where batteries have held traditionally a large advantage.
The product's developers engineers and scientists at Nanyang Technological University (NTU) in Singapore Tsinghua University in China and Case Western Reserve University in the United states believe the storage capacity by volume
The device also maintains the advantage of charging and releasing energy much faster than a battery.
Conversely batteries have high energy density and low power density which means they can last a long time
By mass supercapacitors might have comparable energy storage or energy density to batteries. But because they require large amounts of accessible surface area to store energy they have lagged always badly in energy density by volume.
Woven into uniforms the battery-like supercapacitors could power displays or transistors used for communication.
In addition The team is interested also in testing these fibers for multifunctional applications including batteries solar cells biofuel cells

#An All-Liquid Battery For Storing Solar And Wind energy You could call it a rainy-day fund.
A team of MIT researchers has built an all-liquid battery prototype that's designed to store excess energy from solar and wind power plants.
or the wind isn't blowing future versions of this battery could release energy captured during more productive times into nations'power grids.
There are already solid batteries sold now to store energy from solar panels. They're mostly used in single homes however.
As solar facilities get larger solid batteries get more expensive and less efficient compared to how much energy the whole facility makes.
The MIT team thinks an all-liquid battery filled with searingly hot molten metals might be a good alternative.
Liquid batteries may be easier (and thus cheaper) to manufacture in larger sizes and they're expected to last longer than solid ones.
The team previously made a prototype all-liquid battery filled with magnesium and an element called antimony.
With this latest version the team has made a battery with lithium and antimony mixed with lead.
Plus the battery can be kept at lower temperatures. It works at 450 degrees Celsius versus 700 degrees Celsius.
and discharging the liquid battery for 1800 hours. From that data it predicts that the battery would lose 15 percent of its capacity after 10 years of daily use.
Engineers have known long about how important storage is to solar and wind energy given their unreliable natures.

#Aluminum olk-and-Shellnanoparticle Boosts Capacity and Power of Lithium-ion Batteries One big problem faced by electrodes in rechargeable batteries,
and provide a dramatic boost in the battery capacity and power. The new findings, which use aluminum as the key material for the lithium-ion battery negative electrode,
or anode, are reported in the journal Nature Communications, in a paper by MIT professor Ju Li and six others.
Most present lithium-ion batteries the most widely used form of rechargeable batteries use anodes made of graphite, a form of carbon.
As a result, previous attempts to develop an aluminum electrode for lithium-ion batteries had failed.

For applications that require a high power-and energy density battery, he says, t probably the best anode material available.
There is much work in the battery field that uses omplicated synthesis with sophisticated facilities, Lou adds,
but such systems re unlikely to have impact for real batteries. Simple things make real impact in the battery field.
The research team included Sa Li, Yu Cheng Zhao, and Chang An Wang of Tsinghua University in Beijing and Junjie Niu,
and Samsung have developed an approach for a solid electrolyte that could greatly improve both battery lifetime and safety,
or an electric car youl find that batteries take up most of the space inside. Indeed, the recent evolution of batteries has made it possible to pack ample power in small places.
But people still always want their devices to last even longer or go further on a charge,
so researchers work night and day to boost the power a given size battery can hold. Rare, but widely publicized, incidents of overheating or combustion in lithium-ion batteries have highlighted also the importance of safety in battery technology.
Now researchers at MIT and Samsung, and in California and Maryland, have developed a new approach to one of the three basic components of batteries, the electrolyte.
The new findings are based on the idea that a solid electrolyte, rather than the liquid used in today most common rechargeables,
They describe a new approach to the development of solid-state electrolytes that could simultaneously address the greatest challenges associated with improving lithium-ion batteries,

Costs have already been coming down steadily, he says. But as for safety, replacing the electrolyte would be the key
The lithium itself is not flammable in the state it in in these batteries. With a solid electrolyte there no safety problem you could throw it against the wall,
ith a solid-state electrolyte, there virtually no degradation reactions leftmeaning such batteries could last through undreds of thousands of cycles. he key to making this feasible,
was finding solid materials that could conduct ions fast enough to be useful in a battery. here was a view that solids cannot conduct fast enough,
That alliance also has led to important advances in the use of quantum dot materials to create highly efficient solar cells and sodium batteries,
While conventional lithium-ion batteries do not perform well in extreme cold, and need to be preheated at temperatures below roughly minus 20 degrees Fahrenheit,
Such batteries provide a 20 to 30 percent improvement in power density with a corresponding increase in how long a battery of a given size could power a phone, a computer,

#Quantity, Dimensions of Carbon black Nanoparticles Crucial for Lithium-Ion Battery Function A Stanford undergraduate has contributed to a discovery that confounds the conventional wisdom in lithium-ion battery design,
and also devised new design rules for better batteries. Graduate student Yiyang Li and undergraduate Sophie Meyer led the collaborative effort to design experiments that disproved an assumption shared by battery designers for more than 20 years:
While lithium-ion batteries needed a substance called carbon black in order to function, the precise amount of that material had not been considered crucial to overall performance."
"Our research demonstrated that isn't true, "said Meyer, who started the experiments when she was a sophomore with no prior experience in materials science.
for supervising Meyer over two years of experiments that included the construction of scores of batteries from scratch
Lithium-ion batteries have been used commonly in laptop and tablet computers, electric vehicles and renewable energy systems for more than two decades.
These batteries typically contain cathode particles through which the electrons flow, an action that enables the battery to charge.
These cathode particles are composed typically of lithium iron phosphate or lithium cobalt oxide, mixed together with carbon black,
Prior to the team's research, the quantity and dimensions of the carbon black nanoparticles weren't considered particularly crucial to a battery's function."
"The industry standard for lithium-ion batteries is a low carbon model say, 5 percent of the total material by weight,
something that varies a great deal within a battery.""Li said that by upping the percentage of carbon black as high as 20 percent in some experiments they found that the cathode particles charged more quickly
So although a battery with a higher carbon black content might charge faster, it would also have less energy
These results point toward possible future experiments to further optimize battery design. But such research would not be emphasized possible,
Li and Meyer worked with their teammates to fabricate hundreds of batteries with different concentrations of carbon black.
Each battery had to be analyzed for composition and performance. Among other things, that required the evaluation of nanometer scale images of the battery materials obtained through Lawrence Berkeley National Laboratory's synchrotron
the Advanced Light source.""I had a lot of questions, and I read a ton of papers in the field,
"Then we had to figure out how to make the batteries: what ratio of carbon black to lithium iron phosphate to polymer binder to use;
