Abstract

Graphene has emerged as a novel, highly promising material with exceptional properties and potential application in a wide range of technologies. As an anode material for lithium-ion batteries, it was shown that it cannot be used in the pure form due to its large irreversible capacity but as part of a composite with other active materials. Transition metal oxides, silicon, and tin have been explored as active anode materials to replace graphite because of their high theoretical capacities. However, these materials have large volume changes during cycling that leads to the failure of the batteries. To resolve this problem, additives have been added to these materials to mitigate this volume change. In recent years, graphene has been employed as an encapsulating agent for these materials. In this chapter, an overview of the work exploring composites made of graphene as a novel support for nanoscale materials that react with lithium and provide high capacities will be presented.
