Active islands inactive electrodes

Partially Blocked Active Electrode and Active Islands on Inactive Electrode... 

Composite electrodes used in the electrochemical processes are often partially active since they are composed of the active powder material and the inactive binder and conductor. The partially blocked active electrode can be characterized by the contiguous fractal with dy < 2.0. In the case of the electrodes composed of the active islands on an inactive support, they are characterized by the non-contiguous fractal with dy < 2.0.121...
