(Integrated microscale flow batteries could power and cool future three-dimensional chip stacks.). Tightly packed electronic components generate a lot of heat. Tiny redox flow batteries will beneath supplying energy also dissipating the heat they produce. Researchers at ETH Zurich and IBM Research Zurich have built a tiny redox flow battery. This means that future computer chip stacks – in which individual chips are stacked like pancakes to save space and energy – could be supplied with electrical power and cooled at the same time by such integrated flow batteries. In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop. The chips are effectively operated with a liquid fuel and produce their own electricity. As the scientists use two liquids that are known to be suitable both as flow-battery electrolytes and as a medium to also effect cooling, excess heat can also be dissipated from the chip stack via the same circuit. The battery is only around 1.5 millimetres thick. The idea would be to assemble chip stacks layer by layer: a computer chip, then a thin battery micro-cell that supplies the chip with electricity and cools it, followed by the next computer chip and so on. Record-high outputPrevious flow batteries (see box) are usually large scale and used mainly in stationary energy storage applications, for instance in combination with wind farms and solar power plants, where they temporarily store the energy produced there so it can be used at a later time. These are the first scientists to build such a small flow battery so as to combine energy supply and cooling. The output of the new micro-battery also reaches a record-high in terms of its size: 1.4 watts per square centimetre of battery surface. Even if you subtract the power required to pump the liquid electrolytes to the battery, the resulting net power density is still 1 watt per square centimetre. In an experiment, the electrolyte liquids are actually able to cool a chip. They are even able to dissipate heat amounts many times over what the battery generates as electrical energy (which is converted into heat while the chip is in operation). Channel system optimised with 3D printingThe most serious challenge in constructing the new micro-flow batteries was to build them in such a way that they are supplied with electrolytes as efficiently as possible while at the same time keeping the pumping power as low as possible. It was important to find the ideal compromise. The electrochemical reactions in the battery occur in two thin and porous electrode layers that are separated by a membrane. The scientists used 3D-printing technology to build a polymer channel system to press the electrolyte liquid into the porous electrode layer as efficiently as possible. The most suitable of the various designs tested proved to be one made of wedge-shaped convergent channels. Interesting for large systems, tooThe scientists have now provided an initial proof-of-concept for the construction of a small flow battery. Although the power density of the new micro-flow battery is very high, the electricity produced is still not entirely sufficient to operate a computer chip. In order for the flow battery to be used in a chip stack, it must be further optimised by industry partners. The new approach is also interesting for other applications: in lasers, for example, which have to be supplied with energy and cooled; or for solar cells, where the electricity produced could be stored directly in the battery cell and used later when needed. The system could also keep the operating temperature of the solar cell at the ideal level. In addition, large flow batteries could also be improved with the optimised approach of forcing the electrolyte liquids through the porous electrodes. Ref.ML-2020/H1CNLC-RD1217P

(In a new concept for battery cathodes, nanometer-scale particles made of lithium and oxygen compounds (depicted in red and white) are embedded in a sponge-like lattice (yellow) of cobalt oxide, which keeps them stable.)  Engineers from MIT propose that a new lithium-oxygen battery material could be packaged in batteries that are very similar to conventional sealed batteries yet provide much more energy for their weight. Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their weight. But such batteries have some pretty serious drawbacks: They waste much of the injected energy as heat and degrade relatively quickly. They also require expensive extra components to pump oxygen gas in and out, in an open-cell configuration that is very different from conventional sealed batteries But a new variation of the battery chemistry, which could be used in a conventional, fully sealed battery, promises similar theoretical performance as lithium-air batteries while overcoming all of these drawbacks. The new battery concept, called a nanolithia cathode battery, is described in the journal Nature Energy in a paper by Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering at MIT; postdoc Zhi Zhu; and five others at MIT, Argonne National Laboratory, and Peking University in China.   One of the shortcomings of lithium-air batteries, Li explains, is the mismatch between the voltages involved in charging and discharging the batteries.  The batteries’ output voltage is more than 1.2 volts lower than the voltage used to charge them, which represents a significant power loss incurred in each charging cycle. “You waste 30 percent of the electrical energy as heat in charging. … It can actually burn if you charge it too fast,” he says.  Staying solid Conventional lithium-air batteries draw in oxygen from the outside air to drive a chemical reaction with the battery’s lithium during the discharging cycle, and this oxygen is then released again to the atmosphere during the reverse reaction in the charging cycle. In the new variant, the same kind of electrochemical reactions take place between lithium and oxygen during charging and discharging, but they take place without ever letting the oxygen revert to a gaseous form.  Instead, the oxygen stays inside the solid and transforms directly between its three redox states, while bound in the form of three different solid chemical compounds, Li2O, Li2O2, and LiO2, which are mixed together in the form of a glass.  This reduces the voltage loss by a factor of five, from 1.2 volts to 0.24 volts, so only 8 percent of the electrical energy is turned to heat. “This means faster charging for cars, as heat removal from the battery pack is less of a safety concern, as well as energy efficiency benefits,” Li says. This approach helps overcome another issue with lithium-air batteries: As the chemical reaction involved in charging and discharging converts oxygen between gaseous and solid forms, the material goes through huge volume changes that can disrupt electrical conduction paths in the structure, severely limiting its lifetime. The secret to the new formulation is creating minuscule particles, at the nanometer scale (billionths of a meter), which contain both the lithium and the oxygen in the form of a glass, confined tightly within a matrix of cobalt oxide. The researchers refer to these particles as nanolithia. In this form, the transitions between LiO2, Li2O2, and Li2O can take place entirely inside the solid material, he says. The nanolithia particles would normally be very unstable, so the researchers embedded them within the cobalt oxide matrix, a sponge-like material with pores just a few nanometers across. The matrix stabilizes the particles and also acts as a catalyst for their transformations. Conventional lithium-air batteries, Li explains, are “really lithium-dry oxygen batteries, because they really can’t handle moisture or carbon dioxide,” so these have to be carefully scrubbed from the incoming air that feeds the batteries. “You need large auxiliary systems to remove the carbon dioxide and water, and it’s very hard to do this.” But the new battery, which never needs to draw in any outside air, circumvents this issue. No overcharging The new battery is also inherently protected from overcharging, the team says, because the chemical reaction, in this case, is naturally self-limiting — when overcharged, the reaction shifts to a different form that prevents further activity.  “With a typical battery, if you overcharge it, it can cause irreversible structural damage or even explode,” Li says. But with the nanolithia battery, “we have overcharged the battery for 15 days, to a hundred times its capacity, but there was no damage at all.” In cycling tests, a lab version of the new battery was put through 120 charging-discharging cycles, and showed less than a 2 percent loss of capacity, indicating that such batteries could have a long useful lifetime.  And because such batteries could be installed and operated just like conventional solid lithium-ion batteries, without any of the auxiliary components needed for a lithium-air battery, they could be easily adapted to existing installations or conventional battery pack designs for cars, electronics, or even grid-scale power storage. Because these “solid oxygen” cathodes are much lighter than conventional lithium-ion battery cathodes, the new design could store as much as double the amount of energy for a given cathode weight, the team says. And with further refinement of the design, Li says, the new batteries could ultimately double that capacity again. All of this is accomplished without adding any expensive components or materials, according to Li. The carbonate they use as the liquid electrolyte in this battery “is the cheapest kind” of electrolyte, he says.  And the cobalt oxide component weighs less than 50 percent of the nanolithia component. Overall, the new battery system is “very scalable, cheap, and much safer” than lithium-air batteries, Li says. The team expects to move from this lab-scale proof of concept to a practical prototype within about a year. “This is a foundational breakthrough, which may shift the paradigm of oxygen-based batteries,” says Xiulei Ji, an assistant professor of chemistry at Oregon State University, who was not involved in this work.  “In this system, commercial carbonate-based electrolyte works very well with solvated superoxide shuttles, which is quite impressive and may have to do with the lack of any gaseous O2 in this sealed system. All active masses of the cathode throughout cycling are solid, which presents not only large energy density but compatibility with the current battery manufacturing infrastructure.” The research team included MIT research scientists Akihiro Kushima and Zongyou Yin; Lu Qi of Peking University; and Khalil Amine and Jun Lu of Argonne National Laboratory in Illinois. The work was supported by the National Science Foundation and the U.S. Department of Energy. Ref.KY605-CR2025VPKY605-NH12VP

Healthcare practitioners may one day be able to physically screen for breast cancer using pressure-sensitive rubber gloves to detect tumors, owing to a transparent, bendable and sensitive pressure sensor newly developed by Japanese and American teams.Conventional pressure sensors are flexible enough to fit to soft surfaces such as human skin, but they cannot measure pressure changes accurately once they are twisted or wrinkled, making them unsuitable for use on complex and moving surfaces. Additionally, it is difficult to reduce them below 100 micrometers thickness because of limitations in current production methods.To address these issues, an international team of researchers led by Dr. Sungwon Lee and Professor Takao Someya of the University of Tokyo's Graduate School of Engineering has developed a nanofiber-type pressure sensor that can measure pressure distribution of rounded surfaces such as an inflated balloon and maintain its sensing accuracy even when bent over a radius of 80 micrometers, equivalent to just twice the width of a human hair. The sensor is roughly 8 micrometers thick and can measure the pressure in 144 locations at once.The device demonstrated in this study consists of organic transistors, electronic switches made from carbon and oxygen based organic materials, and a pressure sensitive nanofiber structure. Carbon nanotubes and graphene were added to an elastic polymer to create nanofibers with a diameter of 300 to 700 nanometers, which were then entangled with each other to form a transparent, thin and light porous structure."We've also tested the performance of our pressure sensor with an artificial blood vessel and found that it could detect small pressure changes and speed of pressure propagation," says Lee. He continues, "Flexible electronics have great potential for implantable and wearable devices. I realized that many groups are developing flexible sensors that can measure pressure but none of them are suitable for measuring real objects since they are sensitive to distortion. That was my main motivation and I think we have proposed an effective solution to this problem."Reference:13C5000PA4K19C050PA4KMLH100PGM01B
