#Drexel Univ. materials research could unlock potential of lithium-sulfur batteries Drexel researchers, along with colleagues at Aix-Marseille University in France, have discovered a high performance cathode material with great promise for use in next generation lithium-sulfur batteries that could one day be used to power
mobile devices and electric cars. Lithium-sulfur batteries have recently become one of the hottest topics in the field of energy storage devices due to their high energy density
--which is about four times higher than that of lithium-ion batteries currently used in mobile devices.
One of the major challenges for the practical application of lithium-sulfur batteries is to find cathode materials that demonstrate long-term stability.
An international research collaboration led by Drexel's Yury Gogotsi, Phd, Distinguished University and Trustee Chair professor in the College of Engineering and director of its Nanomaterials Research Group, has created a two-dimensional carbon/sulfur nanolaminate that could be a viable candidate for use as a lithium-sulfur
Distinguished professor in Drexel's Department of Materials science & Engineering, has been used as the basis for much of Drexel's materials research intended to find better materials for batteries.
This structure is key to their potential for being used as electrode materials for lithium-sulfur batteries.
Currently, sulfur infiltrated carbon nanomaterials have demonstrated to be the most promising cathode materials for Li-S batteries.

Supercapacitors are a bridge between conventional capacitors and batteries, combining the advantageous properties of high power, high energy density and low internal resistance,
which may replace batteries as a fast, reliable and potentially safer power source for electric and portable electronic devices in future, said Singh.

Solar fuel cell To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution now
even though this is still some way off the fifteen percent achieved by silicon cells coupled to a battery.

#New NMR tool helps scientists study elusive battery reaction (Nanowerk News) When working on a unique lithium-germanide battery with colleagues from the National University of Singapore,
scientists at Pacific Northwest National Laboratory encountered a catch-22: They knew an exciting reaction was occurring inside the battery that increased its energy storage capacity dramatically
-but they could not observe the reaction. The researchers needed to understand the process, but taking the battery apart caused the reaction to stop.
PNNL scientist Jian Zhi Hu displays a tiny experimental battery mounted in NMR apparatus used to observe the chemical reaction inside.
To solve the problem, the PNNL scientists encapsulated the battery cell in a plastic holder to allow magnetic waves to penetrate it
and developed a powerful nuclear magnetic resonance (NMR) technique to"see "and understand the electrochemical reactions taking place inside.
lithium-germanide battery and demonstrated how their unique NMR"camera"can be used to examine it
and gather data about reactions that can be observed only as they are happening inside a battery("Probing Lithium Germanide Phase Evolution and Structural Change in a Germanium-in-Carbon nanotube Energy storage system").
"Why It Matterslithium-ion batteries have many uses besides powering cell phones and laptops. Developing safer, more powerful cells with longer life is a worldwide challenge,
Germanium can take on more lithium during the reaction than other materials-making it a promising component for delivering higher battery capacity and superior discharge speeds,
but high battery performance resulting from its favorable uptake of lithium may be a factor in making lithium-germanide batteries attractive in the marketplace.
Scientists can create high-energy density batteries by using lithium with a number of different materials.
By using the NMR process to look inside the battery and observe this reaction as it happened,
a battery performs well for a few charging-discharging cycles, but fades rapidly after that. Using the"core-shell"structure,
however, the battery can be discharged and charged thousands of times. What's Next? Scientists are testing many different materials,
including sulfur, cobalt, magnesium, manganese and others, to use with lithium in making batteries. Many of these materials are potentially useful,
The NMR technique used to enhance the performance of the lithium-germanide reaction may prove useful to scientists working on other types of batteries
"It's all about how to engineer the battery to make it safer and more powerful with a longer life,"said Jian Zhi Hu of PNNL, the lead NMR investigator and a collaborator in the project with Kian Ping Loh,
the leader of the team at the National University of Singapore where the battery was developed."
you have to understand the electrochemistry in the battery. Using NMR to understand hard-to-observe battery reaction phases is useful
when they exist only inside the battery. The procedure could lead to additional opportunities to collaborate with other researchers

however, will require extremely low-power sensors that can run for months without battery changes or, even better,
Where its predecessors could use a solar cell to either charge a battery or directly power a device,
and it can power the device directly from the battery. All of those operations also share a single inductor the chip main electrical component which saves on circuit board space
the chip power consumption remains low. e still want to have battery-charging capability, and we still want to provide a regulated output voltage,
Ups and downs The circuit chief function is to regulate the voltages between the solar cell, the battery,
If the battery operates for too long at a voltage that either too high or too low, for instance, its chemical reactants break down,
the new design helps solve many key problems affecting mobile displays such as how to provide an always-on display function without requiring more frequent battery charging
'Our group has pioneered the idea of using lithium-ion batteries to search for catalysts, 'Cui said.'
But in 2014, Stanford chemist Hongjie Dai developed a water splitter made of inexpensive nickel and iron that runs on an ordinary 1. 5-volt battery.
'Marriage of batteries and catalysis To find catalytic material suitable for both electrodes, the Stanford team borrowed a technique used in battery research called lithium-induced electrochemical tuning.
The idea is to use lithium ions to chemically break the metal oxide catalyst into smaller and smaller pieces.'
The technique has been used in battery research for many years, but it's a new approach for catalysis. The marriage of these two fields is very powerful
have developed a new method to see inside battery-like devices known as supercapacitors at the atomic level.
where they can be used alongside batteries to enhance a vehicle performance. By using a combination of nuclear magnetic resonance (NMR) spectroscopy
They are used also in flashes in mobile phones and as a complementary technology to batteries in order to boost performance.
when placed alongside a battery in an electric car, a supercapacitor is useful when a short burst of power is required,
such as when overtaking another car, with the battery providing the steady power for highway driving. upercapacitors perform a similar function to batteries
and the paper lead author. heye much better at absorbing charge than batteries, but since they have much lower density,
and that might make them a high-power alternative to batteries. At its most basic level, a battery is made of two metal electrodes (an anode and a cathode) with some sort of solution between them (electrolyte.
When the battery is charged, electrolyte ions are stored in the anode. As the battery discharges, electrolyte ions leave the anode
and move across the battery to chemically react with the cathode. The electrons necessary for this reaction travel through the external circuit,
generating an electric current. A supercapacitor is similar to a battery in that it can generate and store electric current,
but unlike a battery, the storage and release of energy does not involve chemical reactions: instead, positive and negative electrolyte ions simply tickto the surfaces of the electrodes when the supercapacitor is being charged.
When a supercapacitor is being discharged to power a device, the ions can easily opoff the surface
and move back into the electrolyte. The reason why supercapacitors charge and discharge so much faster is that the tickingand oppingprocesses happen much faster than the chemical reactions at work in a battery. o increase the area for ions to stick to,
we fill the carbon electrode with tiny holes, like a carbon sponge, said Griffin. ut it hard to know what the ions are doing inside the holes within the electrode we don know exactly what happens
while it charges. n a battery, the two electrodes are different materials, so different processes are said at work
and more powerful Lithium ion batteries (LIBS) are a huge technological advancement from lead acid batteries which have existed since the late 1850.
Lithium-ion cells with cobalt cathodes hold twice the energy of a nickel-based battery and four times that of lead acid.
Despite being a superior consumer battery, LIBS still have some drawbacks. Current manufacturing technology is reaching the theoretical energy density limit for LIBS
These types of batteries, in all of their different lithium-anode combinations, continue to be an essential part of modern consumer electronics
The Korean team tried a totally new approach in making the batteries. According to Dr. Kimoon Kim at IBS, e have investigated already high
The new battery is built from pumpkin-shaped molecules called cucurbit 6 uril (CB 6) which are organized in a honeycomb-like structure.
The physical structure of the porous CB 6 enables the lithium ions to battery to diffuse more freely than in conventional LIBS
and exist without the separators found in other batteries. In tests the porous CB 6 solid electrolytes showed impressive lithium ion conductivity.
To compare this to existing battery electrolytes, the team used a measurement of the lithium transference number (tli)
They also subjected the batteries to extreme temperatures of up to 373 K (99.85°C), well above the 80°C typical upper temperature window for exiting LIBS.
In the tests, the batteries were cycled at temperatures between 298 K and 373 K (24.85°C and 99.85°C) for a duration of four days and after each cycle the results showed no thermal runaway and hardly any change in conductivity.
