A porous battery electrode for a rechargeable battery includes a monolithic porous structure having a porosity in the range of from about 74% to about 99% and comprising a conductive material. An active material layer is deposited on the monolithic porous structure. The pores of the monolithic porous structure have a size in the range of from about 0.2 micron to about 10 microns. A method of making the porous battery electrode is also described.
