제목 3,4-Ethylenedioxy thiophene electrolyte with low interfacial resistance for all solid polymer battery
초록 The demand for lithium secondary batteries in the middle or large sized battery market such as electric vehicles and ESS has increased, and the market for secondary batteries has been developing, but lithium ion batteries have a risk of liquid electrolyte. Lithium polymer batteries have attracted attention, but existing solid polymer electrolytes have a problem that their ionic conductivity efficiency is lower than that of liquid electrolyte. To solve this, we developed an electrolyte capable of minimizing the interface resistance with homogeneous polymer electrodes by introducing oligo(3,4-ethylenedioxy thiophene), a thiophene-based derivative with excellent electrical conductivity. A new type of lithium secondary battery which reduces the interface resistance between the electrode and electrolyte is proposed by introducing poly(EDOT-co-DMTP) as an anode material, p-doped PEDOT as a cathode material and oligo (3,4-ethylenedioxy thiophene) as an electrolyte.
