Results of the last 10 years of our investigations on the use of reticulated vitreous carbon (RVCA (R)) 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 RVCA (R) 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 zinc-carbon 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 RVCA (R) are promising in terms of the application of these kinds of electrodes in electrochemical capacitors. The pseudocapacitance of a Pd-Rh/RVCA (R) composition may reach 540 F g(-1).
