because batteries and fuel cells simply aren practical. The process developed at EBI can be used to selectively upgrade alkyl methyl ketones derived from sugarcane biomass into trimer condensates with better than 95-percent yields.
#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. Simpler manufacturing process This 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.
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 foldable In 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
Viswanathan adds that 24m new battery design ould do the same sort of disruption to lithium ion batteries manufacturing as
keeping their batteries charged. A group of researchers at KAIST has developed a wireless-power transfer (WPT) technology that allows mobile devices to be charged at any location and in any direction,
#Research Team Improves Lithium air batteries For Electric car Industry A research team from Carnegie mellon University and the University of California,
Berkeley, has found that blending together different types of salts in the electrolytes within lithium air batteries can increase the batteriescapacity
Lithium air batteries will soon be a strong competitor to lithium ion batteries, which currently dominate the battery-run electronics market.
Lithium air batteries are especially promising for the electric car industry, as they allow electric car battery packs to be smaller
and more lightweight and could hold more than twice as much energy as lithium ion batteries. Batteries consist of one electrode on either side an anode and a cathode and an electrolyte between them.
Lithium ion batteriescathodes typically contain heavy metal ions like manganese, cobalt or iron, but in lithium air batteries, the much lighter oxygen in a sense acts as the cathode, creating a more efficient design.
Electrolytes consist of a salt and a solvent to dissolve the salt. he electrolytes used in batteries are just like Gatorade electrolytes,
says Venkat Viswanathan, assistant professor of mechanical engineering at Carnegie mellon. very electrolyte has a solvent and a salt.
So if you take Gatorade, the solvent would be water and the salt would be something like sodium chloride, for instance.
However in a lithium air battery, the solvent is dimethoxyethane and the salt is something like lithium hexafluorophosphate. arlier this year,
a team led by Viswanathan and Assistant professor Bryan Mccloskey from the University of California, Berkeley, published a paper in Nature Chemistry,
the researchers were able to make the lithium air batteries last four to five times longer. owever, adding water is not a perfect solution,
because it comes at the cost of being able to recharge the battery, cautioned Viswanathan,
while water increased the battery capacity, it also catalyzed additional parasitic reactions, which prevented the batteries from being recharged.
Viswanathan, Mccloskey and their colleagues Mechanical engineering Ph d. Student Vikram Pande, Abhishek Khetan, a visiting Ph d. student,
The paper, titled nhancing Electrochemical Intermediate Solvation through Electrolyte Anion Selection to Increase Nonaqueous Li-O2 Battery Capacity, explains that salts are the key not solvents
we increased the battery capacity by triggering the so-called solution process without compromising on rechargeability.
Nitrate anion from the lithium nitrate salt does the trick by selectively dissolving previously insoluble products without facing the fundamental bottleneck produced by solvent additives. hough this research is an important advancement for lithium air batteries,
the methods the researchers have developed will also be very impactful in other areas of battery research. his research is going to be very important for another big battery technology,
or insoluble is really important for most new battery ideas that are out there. ource:

how smaller batteries give more power to UK solar households When Elon musk, the chief executive of Tesla, took to the stage in California in April to launch a solar battery for the home,
the audience hollered and whooped at every detail. On the other side of the Atlantic, a more modest, quieter challenger plans to take on the US electric car giant.
The similarity lies in the product the Powervault battery which stores energy from domestic solar panels. ome people, especially if they don have solar panels,
just assume solar panels come with a battery, says Joe Warren, Powervault managing director. They don. Home energy generation has blossomed in the UK over the past four years,
Tesla and other players in the emerging solar battery market aim to supply the means for householders to store energy produced during the sunniest part of the day for use at peak times,

it will charge the batteries until they are full and if it notices that you are importing electricity,
and reduce the amount of energy being imported from the grid by offsetting that with the energy in the battery.
If you made the battery bigger, you could store the energy for longer but the problem with that is it would cost a lot more.
