Web4 mei 2006 · Nafion 112 membrane was purchased from DuPont. The starting Nafion 112 membrane was first converted to form and then lithiated as previously described in Ref. 19. The pretreatment procedure is briefly summarized here. The membrane was put in at 80°C for , then immersed in a solution of for and finally washed with deionized water.
Web3 apr. 2024 · The melting point of H + Nafion determined by DSC was about 275 °C [ 25 ]. It is significant that the melting in Nafion occurs over a very broad temperature range below 275 °C [ 25 ]. Therefore, thermal transitions in H + Nafion above 200 °C are usually associated with crystalline melting [ 43, 46, 47, 48 ]. WebLithiated Nafion 112 ionomer was characterized by FT-IR spectroscopy, AC impedance, and cyclic voltammetry. The ionomer swollen with mixed solvents of propylene carbonate (PC) and ethylene carbonate shows ionic conductivity of 8.18×10 −5 Scm −1 at 25°C and good electrochemical stability to allow operation in Li/ionomer/LiCoO 2 cells.
