Univ. of Tokyo researchers demonstrate new “oxygen-rocking” battery

Univ. of Tokyo researchers demonstrate new “oxygen-rocking” battery 25 December 2013 Researchers at the University of Tokyo have developed a battery based on the concept of a combination of a perovskite-type cathode and a low-electrode-potential anode that can achieve high energy densities through the use of organic rather than aqueous electrolytes. The work is derivative of their earlier investigation into a “oxygen-rocking batteries” reported in 2012. (Earlier post .) Batteries based on this system allow the use of various anode materials, such as lithium and sodium, without the requirement to develop new cathode intercalation materials. In the new study reported in the Journal of the American Chemical Society , they used the concept and demonstrated a new battery based on a CaFeO3 cathode with a sodium anode, in conjunction with a NaClO4 /triglyme electrolyte. We have r...
