Cu is taken as the relative standard, because it is the most widely used material for the negative electrode current collector (at least in Li-ion cells). The following materials have been examined as positive current collectors in lithium batteries. For high voltage Li-ion cells, Al is the material of choice.
The current collector is one of the important components of a lithium-ion battery. It can not only carry the electrode active material, but also collect the current generated by the electrode active material to form a larger current output, which improves the charge / discharge efficiency of the lithium-ion battery.
Commercial electrodes in LIBs are fabricated by slurry casting on metal foil current collectors . The current collector serves as a mechanical support for the electrode. Polymeric binder, usually polyvinylidene difluoride (PVDF), is used to improve the integrity of the electrodes and adhesion between electrodes and current collectors.
A Ni–Al–Si–C alloy with various trace elements and up to 10% of Mo, W, Nb, Zr was suggested as the positive electrode current collector of Li-ion cells. Lanthanides are included up to 0.5%, and other elements as required (all metallic except for Si and C). 110
