HIGH-ENERGY ELECTRODES WITH CONTROLLED MICROSTRUCTURES FOR ELECTROCHEMICAL DEVICES AND METHOD FOR PREPARING THE SAME

摘要

Disclosed herein are electrodes for electrochemical devices and methods of making the electrodes. The electrodes include an electrode body comprising a plurality of channels wherein at least a portion of the channels extend from the first surface to the second surface of the electrode body. In the methods of making the electrodes, a combination of binder chemistry, solid loading, dispersant, types of carbon network, substrate surface modification, and drying temperature and time can be used to control the channel size and density.
