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.
Ingredients of current collectors Ingredients used for current collectors for lithium-ion batteries differ by electrode. The most commonly used material for the anode current collector is copper foil, since it offers high electrical conductivity and good stability against electrochemical reactions within the operating range of the carbon electrode.
Conventional current collectors, Al and Cu foils have been used since the first commercial lithium-ion battery, and over the past two decades, the thickness of these current collectors has decreased in order to increase the energy density.
Six different types of current collector materials for batteries are reviewed. The performance, stability, cost and sustainability are compared. 2D and 3D structures of foil, mesh and foam are introduced. Future direction and opportunities for 2D and 3D current collectors are provided.
The surface/interface of current collectors in lithium batteries is gradually becoming one of the key factors to improve the overall performance. The thickness, material composition, surface morphology, and intrinsic properties of current collectors are crucial for understanding chemo-mechanical changes during electrochemical reactions.
This article reviews the current research progress of single or composite current collector materials such as copper, aluminum, nickel, stainless steel, carbon, and carbon-coated aluminum foil in lithium-ion batteries.
