Silicon anodes for improved capacity lithium-ion batteries

Imperial Innovations, Nexeon

Improving energy-storage capacity of lithium-ion batteries is a key target for meeting the energy demands of many types of electronic devices such as laptops and electric vehicles. Currently, graphite anodes are used in lithium-ion cells, but the demands of technology have advanced to the point where carbon is operating near its theoretical limit. In order to meet rising power demand while keeping batteries small, Imperial

College spin-out Nexeon has been investigating the properties of silicon as an anode material.
