Li-Pol batteries EEMB with increased discharge current

09.12.2016

EEMB has developed several series of lithium polymer batteries (Li-Pol) with low internal resistance and increased discharge current - LP/HA, LP/HB, LP/HC, LP/HD.

The maximum continuous discharge current of the new series depends on the initial battery capacity (C) and can reach the following values: 5C-10C (for the HA series); 10C-15C (for HB series); 15C-20C (for HC series) and 20C for HD series. For example, an LP503048HA-PCM-LD battery with an initial capacity of 550 mAh can be discharged with a maximum continuous current of up to 5,5 A, while the voltage drop across the internal resistance will be only about 0,6 V (under normal conditions).

This type of battery is in demand in unmanned aerial vehicles, aeromodelling, power tools and other applications that require increased autonomous energy over a certain period of time.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Breathing gets harder 09.04.2005

Stations scattered around the world that measure carbon dioxide in the air, for the second year in a row, have noted an unusually large increase in this indicator: more than three parts per million parts of air per year.

The oldest such station has been operating in the Hawaiian Islands since 1958, and such cases of sustained growth have not yet been observed. The increase for the year ranged from 0,8 to one and a half parts per million. True, in some years there were two and almost three parts per million, but this happened during the El Niño years - the activation of warm currents in the ocean.

Warm water can hold fewer gases in solution than cold water. But in recent years there have been no strong El Niños. Perhaps, say some ecologists, the ability of the biosphere to absorb carbon dioxide emitted by burning fuel has been exhausted. Too many forests have been cut down. If this is so, then we are waiting for a rapid, by historical standards, and a radical change in the Earth's climate.

According to another theory, excess carbon dioxide is thrown into the air by forest fires that have become more frequent in recent years. On the island of Borneo, peat deposits are almost constantly smoldering. Experts agree that we must wait and see what happens to the atmosphere next.
