Abstract

Many studies of recent decades have specifically examined high-performance carbon materials for application in next-generation batteries. Recently, an innovative technology named solution plasma (SP) has been drawing attention to carbon material synthesis. The most attractive aspect of SP is that, through this technology, the physical and chemical properties of synthesized carbon can be altered easily by varying the organic solvent. However, the conductivity of the SP synthesized carbon requires further improvement for application as an electrode material. In this study, molecules having π orbitals such as naphthalene or anthracene were introduced into benzene solvent to improve the conductivity of the synthesized carbon. Results of resistance measurements show that the resistance values of naphthalene (26.4 Ωcm) and anthracene (16.6 Ωcm) introduced carbons were improved by about 4 and 6 times, respectively, compared to carbon obtained from pure benzene (104 Ωcm). Details of the effects of solutes on the crystallinity and conductivity of the synthesized carbon are discussed.
