Abstract: A redox flow battery includes positive and negative electrodes respectfully located in half-cells separated by a porous silicon wafer separator formed by MEMS Technology. The first half cell and the second half cell each preferably include a plurality of dividers or barriers configured to create flow channels which introduce turbulence ensuring the electrolytes are changing or mixing at surfaces of the electrodes and the membrane. Also disclosed is a solar energy generation and storage system which includes a photovoltaic cell and an electrochemical energy storage battery which share a common electrode. Also disclosed is a membrane-less redox flow electrical energy storage battery, having a cathode electrode, an anode electrode formed of a porous silicon substrate in which surfaces of the pores of the porous silicon substrate are coated at least in part with a metal silicide, and an electrolyte.
