Solution was found, which helped to nanotechnology. Litivo-ion batteries work by transferring lithium ions from the anode, usually made from coal, to metalooksidnomu cathode. Ugolny anode can hold no more than one ion to six carbon atoms. Silicon anode, by comparison, holds a much greater charge lithium ion 4.4 per silicon atom. However, when charging the silicon increases the possibility of four, which leads to its splitting into as the anode and makes it so unfit for use in batteries. The discovery lies in the fact that silicon nanoislands width of 100 nanometers are not torn at expansion. This phenomenon remains a mystery. Perhaps their small size prevents the rupture might have something else, or they svoistva fundamentally different. However, the results Yi kui, are striking. According to the latest published figures, Yee kyi uvelisil number of charge-discharge cycles from 30 to 1000 times, resulting in capacity has reached more than 4200 index miliamper hour, which is 10 times higher than conventional lithium-ion battery. Imagine a laptop that can operate without recharging for two days, or electric car, the traveler on a single charge from Moscow to the Crimea. Increased battery capacity will impact literally the whole, increasing life – and dimensions – cell phones, laptops, and possibly even leading to the emergence of practical electric vehicles. Furthermore, while modern lithium-ion batteries for the most part stable and secure, numerous press reports about Explosions notebooks indicate the need for careful attention to the aspect of safety. "We have reason to believe that silicon anode using nanotechnology will be safer," said Yee kyi.
