‘Yolk and shell’ batteries Charge your smartphone in 6 minutes


American and Chinese scientists have prepared such experimental mobile batteries that can be charged in very little time as compared to normal batteries while their full charging capacity will also be 4 times more than the other batteries.

Low capacity batteries are a big problem in high sped smart phones and tablets while their charging time is also a huge problem. Several times, we are in a hurry to go somewhere but the slow charger increases our trouble. But now American and Chinese scientists have now prepared a battery with small capsules of aluminum through which not only the smart phones can be charged in just 6 minutes but there will be 5 times more charging capacity in these batteries as compared to lithium ion batteries. The scientists of Massachusetts Institute of technology (MIT) and Chinese Sangue University put an aluminum capsule in a shell made by titanium dioxide so that aluminum can get the place to shrink and expand after which aluminum capsule was put along with an electrolyte liquid.

Scientists have prepared only 50 nanometer long aluminum capsule for experimental purposes while the shell of titanium dioxide is only four nanometers thick. When it was experimented on a lithium ion battery then a 1.2 ampere hour per gram of space was seen while the charging capacity in graphite is only 0.35 ampere hour per gram. Apart from capacity, these types of batteries can also be charged in just 6 minutes.
