Researchers of the Technical College of Illinois in Chicago synthesized several types of two-dimensional materials, which can serve as catalysts in lithium-air batteries, increasing their energy intensity up to 10 times.
The materials of the Materials tested 15 different types of 2D of dichalcogenides of transition metals (DPM), the feature of which is high electrical conductivity and quick electron transfer. They help increase the speed of chemical reactions inside the battery, and depending on the type of material from which the catalyst is made can significantly improve the ability to accumulate and transmit energy.
During the tests of 2D materials on an experimental lithium-air battery, they increased its energy intensity up to 10 times, compared with traditional catalysts. One of the reasons for the high efficiency of two-dimensional DPM is that they help speed up both charging and device discharge.
According to scientists, lithium-air drives with 2D materials will allow electric vehicles to pass 500-750 km on one charge, which will become a real revolution in electronics. Although lithium-ion batteries are much easier and able to store more energy than lithium-ion, but they are still at the stage of experimental development.
Another innovative solution in the same direction was presented by researchers from Michigan University. They created a prototype
