R&D OF REDOX SUPER CAPACITOR FOR HYBRID CAR AND ON VEHICLE TEST

摘要

A specially designed redox battery named as redox super capacitor (RSC) was developed for power storage applications. Characteristics of the RSC was demonstrated with a 10kW system on an electric vehicle. Feasibility of RSC was studied for power storage systems and the estimated performance was compared with those of double layer capacitor, lead acid battery ,nickel metal hydride battery and lithium ion battery. It is concluded that the RSC is most suitable for PV and wind power generating systems to reduce unfavorable fluctuation from those system. To improve the cell performance, a small testing cell with apparent electrode area of 0.28cm~2 has been developed and tested to evaluate carbon fibers for electrodes of the redox super capacitor, which is filled with the electrolyte solutions of redox ions such as (V(II/III)-V(IV/V) and gives high power output like as super capacitors. The testing cell was operated potetiostatically by CV (cyclic voltammetry),and the analysis of reaction mechanism on the positive electrode by coulo-gavanometry shows same kind of self-catalytic reaction.
