High surface area, good electrical conductivity, and low weight. Aluminum foil is used as a cathode current collector for Lithium-ion batteries. It is a critical component in the construction of the battery, as it helps to conduct electricity and acts as a barrier to prevent the electrolyte from leaking.
Moreover, the carbon coating improves the interface between the aluminum foil and the cathode layer, thus resulting in an overall decrease of the charge transfer impedance. Finally, satisfactory electrochemical performances were achieved using carbon coated aluminum foil.
It is a critical component in the construction of the battery, as it helps to conduct electricity and acts as a barrier to prevent the electrolyte from leaking. HDM is the leading supplier of battery foil materials for lithium-ion energy storage technology in the Asia-Pacific region.
A C-NERGY™ Li-Quid 101 current collector dispersion (TIMCAL) was used as coating slurry for the aluminum foil carbon coating. Aluminum (20 μm, purity >99.9%) was coated with carbon by casting C-NERGY™ Li-Quid 101 dispersion using a handle profile-bar coater (BG Set 220, MTV-Messtechnik) with 6 μm deep grooves.
The carbon-coating layer inhibits aluminum substrate corrosion in aqueous NMC slurry. The carbon coated aluminum foil as a current collector shows excellent stability. The carbon-coating layer reduces the charge transfer resistance of NMC electrodes. NMC electrodes on carbon coated aluminum deliver high capacity of 126 mAh g −1. 1. Introduction
When the Al-cc foil was used instead, the electrodes performance was generally higher. In particular, using a carbon coating thickness of 2 μm resulted in electrodes capable to deliver capacity of ca. 117 mAh g −1 at 1C rate while using the 5 μm thick carbon coating resulted in a delivered electrode capacity of 126 mAh g −1 (at the 50th cycle).
