#Aluminum olk-and-Shellnanoparticle Boosts Capacity and Power of Lithium-ion Batteries One big problem faced by electrodes in rechargeable batteries,
degrading the battery performance over time. Now a team of researchers at MIT and Tsinghua University in China has found a novel way around that problem:
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.
Lithium metal, for example, can store about 10 times as much energy per gram, but is extremely dangerous,
Also, the liquid electrolyte in contact with aluminum will always decompose at the required charge/discharge voltages,
forming a skin called solid electrolyte interphase (SEI) layer, which would be ok if not for the repeated large volume expansion and shrinkage that cause SEI particles to shed.
As a result, previous attempts to develop an aluminum electrode for lithium-ion batteries had failed.
hat separates the aluminum from the liquid electrolytebetween the battery two electrodes. The shell does not expand
and the aluminum inside is protected from direct contact with the electrolyte. The team didn originally plan it that way,
says Li, the Battelle Energy Alliance Professor in Nuclear Science and Engineering, who has a joint appointment in MIT Department of Materials science and engineering. e came up with the method serendipitously,
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,
This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.
All these properties combined make it a tremendous conductor of heat and electricity. A defectree layer is also impermeable to all atoms and molecules.
because a jump between two tightly-packed stones requires less energy. A band gap is much the same;
#Solid electrolyte Paves the Way for Rechargeable batteries with Almost Indefinite Lifetimes Engineers from MIT and Samsung have developed an approach for a solid electrolyte that could greatly improve both battery lifetime and safety,
while providing a significant boost in the amount of power stored in a given space.
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,
could greatly improve both device lifetime and safety while providing a significant boost in the amount of power stored in a given space.
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,
The electrolyte in such batteries typically a liquid organic solvent whose function is to transport charged particles from one of a battery two electrodes to the other during charging
Others have attempted to find a solid replacement for the liquid electrolyte, but this group is the first to show that this can be done in a formulation that fully meets the needs of battery applications.
Solid-state electrolytes could be real game-changer, Ceder says, creating lmost a perfect battery, solving most of the remaining issuesin battery lifetime, safety, and cost.
Costs have already been coming down steadily, he says. But as for safety, replacing the electrolyte would be the key
Ceder adds: ll of the fires youe seen, with Boeing, Tesla, and others, they are all electrolyte fires.
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,
drive a nail through it there nothing there to burn. he proposed solid electrolyte also holds other advantages,
he says: 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,
Ceder says, 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,
he says. hat paradigm has been overthrown. he research team was able to analyze the factors that make for efficient ion conduction in solids,
and home in on compounds that showed the right characteristics. The initial findings focused on a class of materials known as superionic lithium-ion conductors
which are compounds of lithium, germanium, phosphorus, and sulfur, but the principles derived from this research could lead to even more effective materials,
the team says. The research that led to a workable solid-state electrolyte was part of an ongoing partnership with the Korean electronics company Samsung, through the Samsung Advanced Institute of technology in Cambridge, Massachusetts,
Ceder says. That alliance also has led to important advances in the use of quantum dot materials to create highly efficient solar cells and sodium batteries,
he adds. This solid-state electrolyte has unexpected other side benefits: 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, the solid electrolyte versions can still function at those frigid temperatures,
Ceder says. The solid-state electrolyte also allows for greater power density the amount of power that can be stored in a given amount of space.
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,
or a car. The team also included MIT graduate student William Richards and postdoc Jae Chul Kim;
Shyue Ping Ong at the University of California at San diego; Yifei Mo at the University of Maryland;
and the Samsung Advanced Institute of technology focusing on the development of materials for clean energy. Publication: Yan Wang, et al.

#Nanoscientists Improve the Stability of Perovskite Solar cells UCLA researchers have taken a step towards next-generation perovskite solar cells by using a metal oxide andwich.
The new design extends the cell effective life in air by more than 10 times, with only a marginal loss of efficiency converting sunlight to electricity.
UCLA professor Yang Yang, member of the California Nanosystems Institute, is renowned a world innovator of solar cell technology
whose team in recent years has developed next-generation solar cells constructed of perovskite, which has remarkable efficiency converting sunlight to electricity.
Despite this success the delicate nature of perovskite a very light, flexible, organic-inorganic hybrid material stalled further development toward its commercialized use.
This is a significant advance toward stabilizing perovskite solar cells. Their new cell construction extends the cell effective life in air by more than 10 times
with only a marginal loss of efficiency converting sunlight to electricity. The study was published online in the journal Nature Nanotechnology.
Postdoctoral scholar Jingbi You and graduate student Lei Meng from the Yang Lab were the lead authors on the paper. here has been much optimism about perovskite solar cell technology,
In less than two years, the Yang team has advanced perovskite solar cell efficiency from less than 1 percent to close to 20 percent. ut its short lifespan was a limiting factor we have been trying to improve on since developing perovskite cells with high efficiency.
Endowed Chair in Engineering at UCLA, said there are several factors that lead to quick deterioration in normally layered perovskite solar cells.
because electricity generated by the cell is extracted through them. Meng said that in this study the team replaced those organic layers with metal oxide layers that sandwich the perovskite layer,
The next step for the Yang team is to make the metal oxide layers more condensed for better efficiency and seal the solar cell for even longer life with no loss of efficiency.
