Abstract:
A system for forming an electrode for a lithium-ion battery cell includes an electrode material, a material-supply mechanism, a wetting mechanism, a debris-generating tool, and a conditioner. The material-supply mechanism is configured to deliver the electrode material. The wetting mechanism is configured to receive the electrode material from the material-supply mechanism and apply a solution to the electrode material to produce a wet precursor. The debris-generating tool is configured to remove a portion of the electrode material from the wet precursor to form a pre-electrode. The conditioner is configured to eliminate the solution from the pre-electrode and thereby form the electrode.
