Abstract: A method of making three-dimensional solid-state electrodes includes the steps of: providing a slurry of one or more active materials, a pore former and/or a solvent, a binder, and a conductive additive; casting the slurry to form a three-dimensional film; and drying, and removing the pore former from, the three-dimensional film to produce a three-dimensional structure characterized by a substantial number of pores having low tortuosity and having their longitudinal axes extend in substantially the same direction between upper and lower surfaces of the film.
