摘要： An electrolytic copper foil, which is particularly suitable for the application of a lithium ion secondary battery, has a shiny side and a matte side with a roughness of less than 2 μm. Based on the total sum of the texture coefficients of a (111) surface, a (200) surface, a (220) surface and a (311) surface of the electrolytic copper foil, the sum of the texture coefficients of the (220) surface and the (311) surface of the electrolytic copper foil is greater than 60%.

摘要： A surface-treated copper foil includes a treated surface, where the peak extreme height (Sxp) of the treating surface is 0.4 to 3.0 μm. When the surface-treated copper foil is heated at a temperature of 200° C. for 1 hour, the ratio of the integrated intensity of diffraction peak of (111) plane to the sum of the integrated intensities of diffraction peaks of (111) plane, (200) plane, and (220) plane of the treating surface is at least 60%.

摘要： Provided are an electrolytic copper foil, an electrode, and a lithium-ion cell. The electrolytic copper foil comprising copper and chloride is analyzed by TOF-SIMS along its thickness direction to obtain a spectrum of a relative depth ratio as X-axis and a relative intensity of chloride versus copper as Y-axis. There is a chloride peak located between 20% and 80% of the relative depth ratio in the spectrum, and the chloride peak is characterized by a maximum relative intensity of chloride versus copper ranging from 0.77% to 5.13% and a full width at half maximum ranging from 2.31% to 5.78%. With above characteristics, the electrolytic copper foil has low density of copper particles, low degree of warpage, and good coating uniformity of the active material applied thereon, thereby optimizing the efficiency of a lithium-ion cell comprising the electrolytic copper foil.

摘要： Electrodeposited copper foils possessing properties for manufacturing lithium ion rechargeable secondary batteries are described, including methods of making the electrodeposited copper foils, methods for making the battery, and the resultant battery. The electrodeposited copper foils have a specific burst strength in the range of 1.5 to 4.3 kPa*m2/g and a tensile strength in the range of 30 to 40 kgf/mm2. The deposited side of the electrodeposited copper foil has a surface hardness in the range of 0.2 to about 2.0 Gpa by nano indentation analysis to resist wrinkling during pressing of the active materials on the electrodeposited copper foil. The foil exhibits reduced copper burr formation and burr size after clipping.

摘要： Provided are an electrolytic copper foil, an electrode comprising the same, and a lithium ion cell comprising the same. The electrolytic copper foil comprises first and second chromium layers each containing 15 μg/dm2 to 50 μg/dm2 of chromium, and has a resistivity of 1.72 μΩ*cm to 2.25 μΩ*cm. First and second surfaces thereof each have a contact angle of 15 to 50 degrees with oxalic acid, the first surface has a lightness of 17.5 to 40 and the second surface has a lightness of 38 to 60. With these characteristics, the electrolytic copper foil has good weatherability and good adhesion strength with the active materials, thereby improving the cycle life of the lithium ion cell comprising the same.

摘要： Provided are an electrolytic copper foil, an electrode comprising the same, and a lithium-ion battery comprising the same. The electrolytic copper foil comprises a drum side and a deposited side opposite each other. The drum side and the deposited side each have a Kurtosis (Sku) in a range of 1.8 to 6.4, a developed interfacial area ratio (Sdr) in a range of 0.06% to 13%, and a texture aspect ratio (Str) in a range of 0.1 to 1. With the surface morphology, the electrolytic copper foil has an improved adhesion strength with the active material, and thus improving the charge-discharge cycle life performance of the lithium-ion secondary battery.
