New technology lithium-air batteries make them closer to practical application
Lithium-air batteries |
Having densities of energy storage, comparable to the energy performance of the liquid fuel, lithium-air (lithium-oxygen) batteries can be a solution that allows owners of electric cars don't worry much about the limits of trip distance on one battery charge. But until now scientists still have to solve a lot of problems, one of which is a layer of lithium peroxide, growing on the electrode surface, which blocks the flow of oxygen, resulting in decreased battery capacity. And finally, scientists have found a method that allows you to avoid this undesirable phenomenon, and this, in turn, will increase the capacity of batteries by five times compared to existing lithium-air and lithium-ion batteries.
