LiO2 can replace Li-Ion

02.02.2016

Despite technological progress in the smartphone industry, users of many models complain about insufficient battery life. The task of creating a high-capacity battery with compact dimensions is urgent, and the best minds in research laboratories are trying to create the battery of the future.

Scientists from the Argonne National Laboratory (USA), the University of Utah (USA), the University of Louisville (USA), the University of Illinois at Chicago (USA), Hanyang University (South Korea) have created a prototype of the so-called "lithium-oxygen" battery. This novelty uses lithium oxide (LiO2) and has five times the capacity of modern lithium-ion batteries (according to the source). Interestingly, attempts have already been made to create a battery of this type, but they have remained at the project stage, since lithium oxide is difficult to synthesize in pure form. The researchers were able to establish that crystalline LiO2 can be stabilized through the use of graphene cathodes.

The results of the study showed that the LiO2 in the battery can remain stable even when the battery is continuously charged and discharged at a relatively low voltage of 3,2 V. According to the inventors, their discovery is an important step towards creating a new type of high-capacity battery.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Stop sign at the back of the head 01.08.2003

On many cars, additional brake lights are now installed at the top of the rear window.

Red lights in this position are more visible from afar, and statistics show that such cars are less likely to be “entered” from behind.

Inventor John Cromarty from Bristol (England) proposes to provide motorcyclists with such a signal by placing a matrix of several hundred red LEDs on the back of the head of a safety helmet.
