Inexpensive and stable—The salt water battery
Jan 09, 2018
Water could form the basis for future particularly inexpensive rechargeable batteries. Empa researchers have succeeded in doubling the electrochemical stability of water with a special saline solution. This takes us one ...
Muon beam analysis of organic matter in samples from space
Dec 19, 2017
Muon has much higher transmissivity than electrons and X-rays. This feature of muon has enabled us to see through volcanoes, pyramids, and nuclear reactors with cosmic-ray induced natural muons. The artificial muon beam in ...
The wet road to fast and stable batteries
Dec 14, 2017
An international team of scientists—including several researchers from the U.S. Department of Energy's (DOE) Argonne National Laboratory—has discovered an anode battery material with superfast charging and stable operation ...
Researchers make solid ground toward better lithium-ion battery interfaces
Dec 12, 2017
Research at Sandia National Laboratories has identified a major obstacle to advancing solid-state lithium-ion battery performance in small electronics: the flow of lithium ions across battery interfaces.
Scientists discover path to improving game-changing battery electrode
Dec 12, 2017
If you add more lithium to the positive electrode of a lithium-ion battery - overstuff it, in a sense - it can store much more charge in the same amount of space, theoretically powering an electric car 30 to 50 percent farther ...
New test procedure for developing quick-charging lithium-ion batteries
Dec 06, 2017
When lithium-ion batteries are charged too quickly, metallic lithium gets deposited on the anodes. This reduces battery capacity and lifespan and can even destroy the batteries. Scientists at the Technical University of Munich ...
High-rate and long-life lithium-ion battery with improved low-temperature performance through a prelithiation strategy
Dec 05, 2017
When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now, Chinese ...
Toward safer, longer-lasting batteries for electronics and vehicles
Nov 29, 2017
The rise of lithium-ion batteries over the past 25 years has enabled much of today's technology, but on occasion, they still catch fire. Recognizing this liability, carmakers and other private industry researchers are focusing ...
Start-up aims at producing sodium-ion batteries
Nov 27, 2017
Two years after the first battery prototype using sodium ions in a standard industrial format was designed, the start-up Tiamat has been created to design, develop and produce this promising technology. This could counter ...
Researchers developed an initial prototype of a solid sodium battery with the potential to store extra energy
Nov 23, 2017
Phones, laptops, electric cars - batteries are everywhere. And to meet the expectations of today's consumers, these batteries are increasingly light, more powerful and designed to last longer. Currently the most important ...
