The Modification of Graphite in Lithium-Ion Batteries and its Applications

Abstract

Lithium-ion batteries (LIB) dominate the battery market because of their excellent performance. However, the potential safety hazard of lithium-ion batteries is still regarded as an important factor hindering their further development. Lithium-ion batteries are highly flammable. In fact, there have been multiple cases of explosions caused by lithium-ion battery which result in severe burns over the past decades. Other concerns including recyclability and low power density produces obstacles to this technology. Graphite is a material with excellent conductivity. It has many outstanding electronic and mechanical properties. The basic and applied research on graphite has become a current frontier and hotspot. Therefore, graphite is also used to modify lithium-ion batteries. Especially using graphite to modify the anode material greatly improves its original performance. This work firstly introduced the physical and chemical properties of graphite. Subsequently, how graphite can enhance the efficiency LIB was introduced. A detailed introduction was given concerning with graphite modified anode materials. This work will promote the application of graphite in lithium-ion batteries.
