Abstract:
1. An electrode precursor comprising an electrically conductive layer and a plurality of electrically conductive porous foam protrusions extending from one side of said electrically conductive layer, wherein said porous foam protrusions have an average protrusion width selected from about 1 μm to about 100 μm; wherein said porous foam protrusions have an average protrusion height selected from about 10 μm to about 10 mm; wherein said porous foam protrusions have an average protrusion spacing between adjacent protrusions selected from 10 μm to about 10 mm; wherein said porous foam protrusions contain spherical macropores, and further contain micropores; and wherein said porous foam protrusions are characterized by an average tortuosity of 1.1 or higher but less than 5 for pores within said porous foam protrusions, and wherein said micropores have a pore-size peak from 3 nm to 50 nm as measured by N
