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： Disclosed are novel copper foils used as components of wireless charging systems. The copper foils can be laminated to produce flexible copper clad laminates, which can then be etched to form printed circuits (coils). The coils can be used as either, or both, of a receiver wireless charging circuit and/or a transmitter wireless charging circuit. Regulation of the chemical and physical properties of the copper foil produces higher efficiencies in the wireless charging system components.
