Silicon nanotube anodes triple the capacity of lithium-ion batteries

07.06.2014

Scientists at the University of California have developed an improved technology for manufacturing lithium-ion batteries. It allows you to triple the battery capacity.

By creating anodes for lithium-ion batteries from silicon dioxide, the developers found a three-fold increase in capacity compared to existing analogues that use carbon.

Silicon dioxide has been used previously as an anode material in lithium-ion batteries. However, the possibilities of obtaining specific unified nanostructures from this material with the required high energy density and long life cycle were limited. Developers were originally focused on using SiO2 as it is an extremely common and environmentally friendly compound.

According to Zachary Favors, part of the research team, they have taken a material used in medical devices, children's toys and even fast food, and modified it for use in next-generation batteries.

Significant stability of silicon nanotubes in the battery makes it possible to increase the service life. During the experiments, 100 full charge/discharge cycles of batteries with SiO2 nanotube anodes were carried out without any loss of energy capacity. Scientists are confident that new batteries will be able to be recharged hundreds of times without losing capacity.

The research of scientists is important for industry, incl. for various electronics and electric vehicles.

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, ... >>

Earth has another satellite 21.06.2016

We are accustomed to consider the Moon the only natural satellite of the Earth, but the gravitational field of our planet is capable of capturing asteroids passing by for some time, making them temporary satellites.

Asteroid 2016 HO3 was first observed on April 27, 2016 by the Pan-STARRS 1 (Panoramic Survey Telescope and Rapid Response System) asteroid observation telescope located on Haleakala Volcano (Maui, Hawaii). This system makes it possible to detect 99% of asteroids larger than 300 m that cross the earth's orbit.

After analyzing the orbit of the found asteroid, astronomers at the Jet Propulsion Laboratory in Pasadena (California, USA) found that simultaneously with the movement around the Sun, it also revolves around the Earth. The asteroid is far enough away to be considered a true satellite of our planet, which is why it was called a quasi-satellite.

More than 10 years ago, astronomers observed the asteroid 2003 YN107 with a similar orbit pattern for some time, but since then it has already left the near-Earth region of space. The new asteroid is much more securely trapped. Calculations show that 2016 HO3 will be a stable quasi-satellite of the Earth for almost a century, and will remain a companion of the Earth for many more centuries.

In its annual motion with the Earth around the Sun, the asteroid 2016 HO3 is closer to the Sun than the Earth for about half the time and passes in front of our planet, and about half the time further and behind. Its orbit is slightly inclined to the plane of the Earth's orbit, so once a year it emerges above it and then dives below it. These "frog" jumps will last for hundreds of years.

The asteroid's orbit around the Earth also performs a slow turn back and forth with a period of several decades. Its loops drift a little ahead or behind, not far away, but not close enough either. The maximum distance is about 100 times the distance from the Earth to the Moon (about 40 million km). At its closest point of the orbit to the Earth, the asteroid is located at a distance of about 38 times farther than the Moon (about 15 million km). In the figurative expression of one of the researchers, this small asteroid seems to be dancing with the Earth.

The size of the found asteroid has not yet been firmly established, but it appears to be larger than 40 meters and less than 100 meters.
