Battery capacity increased by 10 times

14.08.2013

The Japanese company Shin-Etsu Chemical has developed a technology that allows 10 to increase the capacity of batteries for mobile devices. The essence of the technology is to replace graphite in lithium-ion batteries with silicon material. Thanks to the new technology, smartphones and tablets will be able to work on a single charge for up to 10 days, while now in active use it is only one or two days.

Modern gadgets have a short battery life, which is due to their size and the peculiarity of their work, when the device regularly searches for available wireless networks to connect to the Internet, regularly receives various information from the Internet, etc.

The new material costs more than graphite, however, as Nikkei emphasizes, this breakthrough will save users from having to charge their smartphone every day or every two days, so the price of new technology is not so high.
In addition to mobile device batteries, the new material could be used in electric vehicle batteries, Shin-Etsu Chemical says.

According to representatives of Shin-Etsu Chemical, manufacturers will be able to start commercial production of the new type of batteries in about 3-4 years.

Shin-Etsu Chemical is the largest chemical company in Japan, founded in 1926, engaged in the production of polymers, silicon products for the semiconductor industry, photoresists, artificial quartz and other materials. With a market capitalization of $28,7 billion and annual sales of $12,7 billion, the company is ranked 450th on Forbes' list of the world's 2000 largest companies.

Batteries are one of the most relevant areas for the work of engineers from various companies. So, in April 2013, the developers of one of the American startups announced that they managed to improve the properties of the electrodes of lithium-ion batteries, which increased their capacity by 30%.

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, ... >>

More than enough water on Mars 17.10.2007

The radar installed on the European spacecraft "Mars Express" shines through the planet to a depth of more than three and a half kilometers. He was able to detect not deep below the surface, as well as in the recesses of the relief, accumulations of ice with a diameter of 50 to 200 kilometers and a giant ice dome with a diameter of about a thousand kilometers.

If all these ice reserves melted, Mars would be covered by an ocean 11 meters deep. Whether they will melt is another question. In recent decades, the average temperature of Mars, especially in the Southern Hemisphere, has been rising by an average of 0,65 degrees Celsius per year.

If this continues, then liquid water will be able to sustainably exist on the planet in 500 years.
