Scientists have learned to charge accumulators in some seconds

Scientists of the Massachusets institute of technology (MIT) managed to develop a material which allows to charge lithium-ionic accumulators for 10-20 seconds, it is told in official press release MIT. Article about opening is published in log Nature. Lithium-ionic power supplies are widely used in portable devices, such as mobile phones and notebooks. Such accumulators possess a high capacity, however on their charging some hours leave. Earlier scientific considered that for long charging slow ions of lithium answer. Computer calculations have shown that they, on the contrary, should move very fast. It was soon revealed that lithium ions really can move fast, but for this purpose it is necessary, that the ion from a surface has got to one of material "tunnels". Scientist, speaking in images, it was possible to create "ring road" for ions of lithium which allows them to move on a surface until they will not get to "tunnel". The material has been opened five years ago, now contributors have only changed a way of its manufacture. It is expected that in sale new accumulators will arrive in two-three years.
