Li Ion Battery Electrodes

Serving as the bridge between external electronics and internal lithium-ion transports, current collectors account for over 90% of the electric conductivity and ∼90% of the mechanical strength of the electrode in lithium-ion batteries (LiB). As such, selecting the right anode and cathode battery foil materials is critical to battery developers seeking to maximize the performance of their cells.
