▎ 摘　　要

NOVELTY - The negative electrode has a negative current collector and an anode active material layer. The anode active material layer includes a silicon-based material. The absolute strength of the anode current collector is greater than or equal to 500 N/m. The silicon-based material contains several silicon-oxygen materials in the components represented by the general formula of Silicon monoxide includes one of Lithium, Magnesium, titanium, and Aluminum. The negative electrode current collector includes one of copper foil, nickel foil, titanium foil, chromium foil and stainless steel foil. USE - Negative electrode for electrochemical device of electronic device (all claimed). ADVANTAGE - The electrochemical device can effectively improve the XY expansion and deformation of the negative electrode active material layer by using the negative electrode such that the cycle performance and safety performance of the electrochemical device can be improved. DESCRIPTION OF DRAWING(S) - The drawing shows the graphical representation illustrating the curve of the circulation capacity. (Drawing includes non-English language text)
