An innovative architecture for climbs batteries lithium-ion, which could allow portable electronic devices to be charged in 10 minutes instead of hours, researchers at the University of California, Riverside's Bourns College of Engineering have developed.
The batteries lithium-ion είναι οι επαναφορτιζόμενες μπαταρίες επιλογής για φορητές συσκευές και ηλεκτρικά οχήματα, ωστόσο παρουσιάζουν κάποια problems. Batteries in electric vehicles are an important componenteye of the vehicle's mass, while in mobile devices they act as a barrier to downsizing.
Silicon is a kind of anodic material that gathers interest because its overall charging capacity is 10 times higher than the graphite-based anode of lithium-ion batteries. Replacing an anodised toner with silicon anodes would result in an increase in the total capacity by 63% and a battery that would be by 40% lighter and smaller.

In a paper titled Silicon Decorated Cone Shaped Carbon Nanotube Clusters for Lithium Ion Battery Anode, published at SMALL, UC Riverside researchers are showing the development of an innovative structure / architecture on this very object. Lithium-ion batteries based on it show very good performance. This particular architecture exhibits excellent electrochemical stability and reversibility, even at high charging and discharging rates - about 16 times faster than toner-based anodes.
The head of the paper is Wei Wang. Among the other contributors include Stingiz and Miriam Ozkan, Elizabeth Rouge, Kazi Ahmed, Hammed Bey, Aaron George and Johnny Wang.
