Electrochemical Stability of Copper in Lithium-Ion Battery Electrolytes
Open accessAbstract
The electrochemical stability of copper substrate was studied in three different lithium‐ion battery electrolytes. Cyclic voltammetry was used to study the oxidation‐reduction behavior of copper in these electrolyte solutions. The reduction of electrolyte and its effect on the oxidation of copper was also studied. Bulk electrolysis was used to quantitatively study the dissolution of copper in dry electrolytes and in electrolytes doped with impurities of or HF. The stability of copper was closely related to the composition of the electrolytes. Impurities dramatically increased the oxidation tendency of copper. © 2000 The Electrochemical Society.

During over-discharging, anode potential increases abnormally leading to anodic dissolution of copper current collector and formation of Cu2+ ions; upon recharging, reverse reaction can form copper dendrites, which may lead to internal short circuit.
“During over-discharging, the anode potential increases abnormally which leads to the anodic dissolution of the copper (Cu) current collector and formation of Cu 2+ ions [37].Upon recharging, the reverse reaction can form copper dendrites, which may lead to internal short circuit [38].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
