A young researcher has succeeded in solving a problem in battery technology over ten years old. He developed a solid body battery with significantly higher performance.
Matthias Young, assistant professor of chemistry and biochemistry at the University of Missouri, has developed a new technology for solid -state batteries in order to make it more secure and efficient. The batteries are considered a promising alternative to conventional lithium-ion batteries that work with liquid electrolytes.
These liquids can be dangerous because they can be flammable with damage or overheating. Solid body batteries, on the other hand, use solid materials that make them more durable and safer. A major problem with the development of these batteries is the so -called interphase layer, which forms on the interface between solid electrolyte and cathode.
This only 100 nanometer thin layer hinders the flow of lithium ion and electrons. This increases the resistance and reduces the performance of the battery. Researchers have been looking for a solution to this problem for over a decade.
Fixed body battery: New technology for more performance
A team around Matthias Young has now developed a new technology for solid -state batteries to understand and overcome this obstacle. Using the so-called 4D scanning transaction electron microscopy, they were able to analyze the atomic behavior of the battery without destruction. They identified the interphase layer as the main cause of loss of performance.
In order to solve the problem, the researchers rely on ultra-thin protective layers that are applied with “oxidative molecular layer separation”. This coating prevents the development of the undesirable interphase layer, while it does not affect the flow of lithium ions.
Will safer batteries soon come with a longer term?
Should this new technology prove itself for solid -state batteries, it could drive the development of technology enormously. Because the batteries would not only be safer, but also more powerful. A higher energy density could provide electric vehicles more range and extend the lifespan of batteries in portable devices.
In addition, they would be more rechargeable and more stable over long periods of time. The technology is still in an early stage of development, but the researchers are optimistic. With further tests and improvements, you will soon want to develop a new generation of solid -state batteries that are more secure, more efficient and sustainable than previous models.
