The current collector is usually a conductive metal mesh, such as nickel foam and stainless steel , responsible for ensuring effective electron transfer to the external circuit, enabling the charge and discharge process in the battery . ... ...
Current collector is an indispensable bridge component between battery and external environment. No matter how much the performance of lithium-sulfur battery is improved by modification such as positive and negative electrode or diaphragm, the final effect cannot be separated from the support of current collector.
When the collector is corroded or dissolved, the contact between the electrode active material and the collector will be reduced, which will lead to the shedding of the active material and the increase of battery impedance.
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.
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.
