Current collector materials
WebOct 15, 2024 · The current collector (CC) collects electrons from electrode materials and transports them to the external circuit. Although the CC is an essential part of battery configuration, it has not received considerable attention because there are “champion materials” such as Al and Cu foils in the commercial market. WebJul 15, 2024 · The anode is usually a graphite-based slurry coated onto a copper foil that is operating as a current collector. The cathode is generally a lithium metal oxide or phosphate (e.g. LiCoO 2, LiMn 2 O 4 or LiFePO 4) slurry, coated onto an aluminium foil current collector [ 9 ].
