文摘

Nanoparticulated iron oxide-hydroxide anodes synthetized in supercritical water. Samples mostly consist of FeO1.5−z spinel-type phases, mean particles sizes ca. 30 nm. Optimal value 500 mAh g−1 at 2C after 100 cycles, 1200 mAh g−1 at C/5 when recovering. The electrochemical response depends on homogeneity at the nanoscale.
