Furuya, Ryota published the artcilePotential dependence of the impedance of solid electrolyte interphase in some electrolytes, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is solid electrolyte interphase electrode potential impedance.
The dependence of the impedances of lithium phosphorus oxynitride (LiPON) thin film and solid electrolyte interphase (SEI) formed by decomposition of some electrolytes on the electrode potential was investigated by electrochem. impedance spectroscopy. A LiPON thin film was prepared on a Ni electrode by radio frequency magnetron sputtering of Li3PO4 under nitrogen atm. The resistance of the LiPON thin film decreased with lowering the electrode potential in an ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) containing 1 M LiTFSA. The similar potential dependence of the impedance of the SEI formed in 1 M LiTFSA/BMPTFSA was observed, suggesting that the Li+ carrier d. in the LiPON thin film and SEI increased with lowering the electrode potential probably due to the doping of Li+ from the electrolyte into the thin Li+ conductors in order to compensate the neg. charge on the electrode. On the other hand, the potential dependence of the SEI formed in LiTFSA-tetraglyme (G4) solvate ionic liquid was insignificant because of the high concentration of Li+ in the SEI and electrolyte. The resistance of the SEI formed in 1 M LiClO4/EC (ethylene carbonate) + DMC (di-Me carbonate) (1 : 1 vol%) did not depend on the electrode potential, suggesting the thin and highly Li+ conductive SEI is formed in the organic electrolyte.
