Lithium batteries have their advantages and disadvantages. One of its biggest cons is that precisely the material they are made from makes them a limited load bearing devicewhich deteriorates after a short time.
However, the fact that they are so easy and cheap to manufacture means that they still exist on the market.
A scientific team from the University of Bayreuth, in Germany, found a way to combine elements with lithium that make it a durable device, with the same component of savings for the pocket of manufacturers, according to a review. Urban Techno.
The study house in Germany, which worked with Chinese scientists, reports in a statement that they developed solid-state lithium-metal batteries with high energy density and stability.
What does this mean? Using a novel nitrate-based additive, they solved incompatibility problems in battery electrolytes, underscoring the importance of molecular design in creating effective additives for quasi-solid-state electrolytes.
They achieved this by integrating a novel nitrate-based additive. This advance has important implications for solid-state batteries. It enables the development of solid-state lithium metal batteries that are not only very safe and durable, but also easy to produce, reported on the website of the University of Bayreuth.
“At the same time, the solid-state nature of the batteries ensures a high level of safety, while their manufacture remains simple. We demonstrate the universality of the approach by creating various types of lithium-metal batteries. In particular, the fabricated Li-S bag cell exhibits superior performance compared to previously documented Li-S bag cells,” said Professor Dr. Francesco Ciucci, Professor of Electrode Design for Electrochemical Power Systems at the University from Bayreuth.
The big problem with lithium batteries is their durability. It happens that, in most cases, they do not usually exceed three years of use. But in the studies of the new invention, they developed a laboratory-scale button-type batteries that could be stably charged and discharged more than 2,000 times.
