Results of the last 10 years of our investigations on the use of reticulated vitreous carbon (RVC Ò ) in various types of cells show that this kind of porous conductive glassy carbon can be successfully used as a matrix for active mass and as a current collector in many primary and secondary batteries. This paper focuses mainly on the use of RVC Ò modified with metals like Pt, Rh, Pd, Ni, Pb and their oxides in construction of the following types of cells: (1) zinc-carbon primary and secondary batteries, (2) rechargeable cell systems with NiOOH cathode, (3) electrochemical capacitors with Pd and Pd-Rh alloys, and (4) lead acid battery. The most important improvement in performance has been achieved with lead-acid and zinccarbon batteries. Especially for the modified zinc-carbon battery, which has been constructed in the popular AA format, manufactured on a small (laboratory) scale, and tested according to the IEC norms as a battery for commercial use, the capacity has been higher by ca. 20% compared with the batteries available on the market. Also, results obtained for thin layers of Pd and their alloys deposited on RVC Ò are promising in terms of the application of these kinds of electrodes in electrochemical capacitors. The pseudocapacitance of a Pd-Rh/RVC Ò composition may reach 540 F g -1 .
