Battery operated devices will run longer between charges with greater amounts of stored energy using a new lithium-ion (Li-ion) battery based on silicon anodes, its developers claim.rnThe technology, which is beingrncommercialised through ImperialrnCollege spin-out Nexeon, replacesrnthe carbon-based anodes used inrnLi-ion batteries with silicon anodes.rnThe developers claim silicon allows a greater charge to be stored within the battery. It is also said to provide much higher performance as an anode material, with charge .densities about 10 times that of carbon.rnSilicon has long been known as a superior anode material but, until now, it has suffered from physical instability when repeatedly charged and discharged.
