Abstract: The energy density of commercial Li-ion batteries (LIBs) using LiCoO2 is adversely affected by the limited access to the Li stored in the CoO2 lattice, which is imposed partially by the instability of carbonate-based electrolytes… read more here.

Abstract: LiCoO2/graphite full-cells with a carbonate-free electrolyte based on lithium bis(fluorosulfonyl)imide and sulfolane (LiFSI/SL) show excellent cycle stability at high temperatures. In this study, we used X-ray photoelectron spectroscopy to investigate the composition of the solid… read more here.
