Characterization and performance of high power iron(VI) ferrate batteries
In this paper we report on the high power discharge performance and impedance characteristics of potassium ferrate (K 2FeO 4) and barium ferrate (BaFeO 4) cathodes in zinc alkaline dry cells. The results show that if ferrate materials can be packaged to maximize the cathode surface area, they may of...

Summary: | In this paper we report on the high power discharge performance and impedance characteristics of potassium ferrate (K
2FeO
4) and barium ferrate (BaFeO
4) cathodes in zinc alkaline dry cells. The results show that if ferrate materials can be packaged to maximize the cathode surface area, they may offer superior performance over electrolytic manganese dioxide at operating voltages exceeding 1.6
V and currents as high as 100
mA/g of active material. |
