Abstract
Provided herein is a method for preparing a battery electrode based on an aqueous slurry. The method disclosed herein has the advantage that an aqueous solvent can be used in the manufacturing process, which can save process time and facilities by avoiding the need to handle or recycle hazardous organic solvents. Therefore, costs are reduced by simplifying the total process. In addition, the batteries having the electrodes prepared by the method disclosed herein show impressive energy retention.
