The paper deals with the investigation of natural graphite electrode materials for lithium-ion batteries. These negative electrode materials operate on the intercalation principle where graphite plays a host role for lithium ions. There is a solid electrolyte interphase (SEI) layer which origins from electrodeelectrolyte interphase. The SEI layer is a fundamental part of lithium-ion battery system and its quality defines and highly affects the overall quality of lithium-ion battery itself. Growth of the SEI layer is connected with the formation of new compounds. The process formation of SEI layer is linked to energy consumption (energy loss). What is most important is the fact that the growth of SEI layer consumes the significant amount of lithium ions provided from a limited positive electrode (cathode) source. In this work, the lithiation method was employed to reduce these undesirable side effects of the SEI growth.
