| 摘要 |
The invention provides, in preferred embodiments, methods, systems, and devices arising therefrom for making battery electrodes, in particular, for lithium-ion batteries. Unlike conventional slurry coating methods that use mechanical means to coat thick pastes of active material, other materials, and solvent(s) onto a substrate, the invention provides for a method to produce electrode coatings onto support in a multi-layer approach to provide highly uniform distribution of materials within the electrode. Problems of differential sedimentation of particles in slurries found in conventional methods are minimized with the methods of the present invention. Also included are systems for producing in large-scale the battery electrodes of the invention. Further included are electrodes produced by the methods and systems described herein. |
