When lithium secondary battery is used for electric car and energy storage device on high power, the reduction of available energy is a problem. This problem influences cell life, stability and energy efficiency. To solve the problem, a completely new type of lithium secondary battery to clear the interfacial resistance between electrode and electrolyte was introduced. In this study, 3,4-ethylenedioxy thiophene (EDOT) oligomer was introduced into the solid electrolyte in order to minimize the interfacial resistance with the poly(3,4-ethylenedioxy thiophene) (PEDOT) based electrode. Also, to improve the lithium salt dissociation ability of the EDOT oligomer, it was blended with poly(vinylidene fluoride) (PVdF) and introduced into the solid electrolyte. All solid polymer battery was manufactured by PEDOT based electrode and oligo(EDOT) and PVdF based electrolyte, and its electrochemical property was evaluated.
