Current Collectors for Lithium-ion Batteries
Posted by Chia-yu Chen on
A typical lithium-ion battery consists of two current collectors, an anode, a cathode, a separator and electrolyte. Current collectors work as a support for electrode materials. They are also electrical conductors between electrode and external circuits. For lithium-ion battery, various current collectors are used such as Al, Cu, Ni, Ti, and stainless steel. Within the above materials, Al and Cu are the most commonly used materials as current collectors. Al is used for a cathode current collector and Cu is used as an anode current collector. Al and Cu current collectors can further be categorized into foil, meshed, foam and...
