ABSTRACT


Among diverse energy storage systems, battery shows advantage in charge/discharge time, easy relocation, and relatively cheap cost compared to other energy storage systems. Lithium ion battery (LIB), the first commercialized battery introduced in 1991 boosted the development of various portable devices. However, recent technologies such as electric vehicles and large intermittent devices, require an alternative energy storage system (ESS) with high capacity and/or cheap cost. Advanced lithium ion battery, sodium ion battery, lithium-sulfur battery, lithium-metal battery, and lithium-air battery has been proposed to address the necessity of next generation ESS. Numerous materials have been reported to satisfy the requirement of these ESS. Among the potential materials, the unique characteristics of carbon including conductivity, cost, morphology tunable, and porosity draw intense interest for ESS.

This review provides an insight of the impact of carbon characteristics (e.g. cost, structure, conductivity) on electrochemical performance and resolving issue associated in different battery systems. The first section describes an economic and ecological benign carbon synthesis method for advanced lithium ion battery. Subsequently, the carbonization temperature impact on final carbon structure and its application in sodium ion battery are introduced. The final two section discuss the effort to resolve issues associated with lithium-sulfur battery and lithium-metal battery. This includes the intense study of carbon conductivity, orientation of carbon film, and carbon size effect.
