Comparative study on surface behaviors of copper current collector in electrolyte for lithium-ion batteries

Self-assembled lamellar alpha-molybdenum trioxide as high performing anode material for lithium-ion batteries

“…Subsequent cycles show smooth data curves probably indicating transformation to amorphous-like structure after the conversion reaction. During anodic scan process the smooth potential plateau at 0.1e0.7 V was attributed to the partial oxidation of SEI layer [33] (organic components deposited on metallic lithium). The other anodic peaks in the range 0.9e2.2 V corresponds to the process of de-intercalation of Li ions.…”

Electrochemical properties of lithium–titanium oxide, modified with Ag–Cu particles, as a negative electrode for lithium-ion batteries

“…The extra charge is related to non-intercalation processes, involving electrode activation, reduction of trace water present in the electrolyte 28 or corrosion of copper current collector. 89,90 Fig. 6 and 7 presents the results of cyclability tests.…”

First-Principles Study on the Adsorption and Dissociation of Impurities on Copper Current Collector in Electrolyte for Lithium-Ion Batteries

“…Shu at el. [ 15 ] observed P, F, and O elements on the surface of Cu foil which was immersed in the electrolyte of lithium-ion batteries for 30 days and deduced that small amounts of decomposition product (such as PF 5 ) during storage of lithium-ion batteries may have vital effects on the stability of copper. Additionally, some researchers deduced that small amounts of decomposition product (such as PF 5 ) during storage of lithium-ion batteries may have vital effects on the stability of copper [ 6 ].…”

“…However, few studies have been made on current collectors, especially the anode current collector, Cu foil. Myung [ 14 ] and Shu [ 15 ] et al found that the presence of HF in the electrolyte was essential in the formation of the metal fluoride layer on the oxide layer of the SEI and water is very important for the formation of passive layers on the surface of the copper current collector. Due to the limitations of these experiments, the microscopic mechanism of the corrosion processes on the surface of Cu foil is not clarified.…”
