The stability at elevated temperatures of a solid electrolyte interphase (SEI) formed on a graphite negative electrode in lithium ion batteries was investigated by storage tests and in situ atomic force microscopy (AFM) observation. When the fully discharged graphite electrode was stored at elevated temperatures, the irreversible capacity in the following(More)
This study examined the electrochemical deposition and dissolution of lithium on nickel electrodes in propylene carbonate (PC) electrolytes containing different concentrations of lithium salts, including LiN(SO2C2F5)2 or LiPF6. The electrode reactions were significantly affected by the electrolyte concentration. The cyclability of the electrodes was(More)
To gain an understanding of the structural properties of the solid electrolyte interphase (SEI) created on the surface of lithium during an electrochemical deposition/dissolution reaction in propylene carbonate (PC) containing different concentrations of LiClO4 (1.09, 3.27 mol kg(-1)), the surface of lithium was examined through transmission electron(More)
