TL;DR: In this article, the performance of commercial lithium ion cells with LiCoO 2 as cathode, artificial graphite as anode and 1.M LiPF 6/EC-DEC-EMC (ethylene carbonate,diethyl carbonate-dimethyl carbonate) with additives (1.1% propylene sulfite (PS)) as electrolyte were aged at 60% and 100% state of charge (SOC) for 6 months at room temperature and the corresponding cycle performance was measured.

TL;DR: In this paper, a gel polymer electrolyte containing 1-butyl-4-methylpyridinium bis(trifluoromethanesulfonyl)imide (BMPyTFSI) ionic liquid is prepared by solution casting method.

TL;DR: In this paper, the passive layer formed on lithium in a PEO20-LiTFSI-5%PC gel polymer electrolyte after different electrochemical processes was characterized using X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectrographs (FTIR), and electrochemical impedance spectrograms (EIS).

TL;DR: In situ micro-FTIR spectroscopy was explored to characterize the solid-solid interface between lithium electrode and polymer electrolytes as discussed by the authors, and the cyclic voltammetric (CV) results indicated that the reduction reactions of oxygen and water as well as the formation of underpotential deposition (UPD) Li occur in the Li/PEO20-LiN(CF3SO2)2 electrolyte interface in different potential region.

TL;DR: In this article, the effect of surface functional groups, containing sulfur, on the performance of the NG anode for a lithium ion battery was investigated and the results of scanning electron microscopy and Raman spectroscopy showed that the surface disorder of NG increased after surface sulfurization.
