Development of Graphene-Based Anode Materials for Li-Ion Batteries

Lithium-ion batteries (LIBs) have become a critical energy storage device in various applications, such as portable electronic devices, electric vehicles, and grid storage, due to their high energy density and good rate capabilities. Carbon-based materials have been widely used as anode materials for lithium-ion batteries. Among them, graphite is the most common anode material used in commercial LIBs. However, it suffers from some issues such as low specific capacity, layer exfoliation and mechanical fracture during cycling, as well as lithium dendrite formation due to constant volumetric changes, which negatively impacts the cyclic performance. Therefore, new anode materials with improved performance are required to meet the increasing demand for high-performance LIBs. Graphene-based materials with attractive properties are promising anode materials to make revolutionary breakthroughs in the field of electrochemical energy storage. In this Project, we will evaluate the electrochemical performance of graphene-based materials obtained from a petroleum waste to develop a high-performance anode material for lithium-ion batteries.
