La_1-x K _x FeO_3-δ: An Anion Intercalative Pseudocapacitive Electrode for Supercapacitor Application.

ABSTRACT: The green energy alternative to a fossil fuel-based economy can be provided only by coupling renewable energy solution solutions such as solar or wind energy plants with large-scale electrochemical energy storage devices. Enabling high-energy storage coupled with high-power delivery can be envisaged though high-capacitive pseudocapacitor electrodes. A pseudocapacitor electrode with multiple oxidation state accessibility can enable more than 1e ^- charge/transfer per molecule to facilitate superior energy storage. K-doped LaFeO₃ (La_1-x K _x FeO_3-δ) is presented here as an electrode having a high pseudocapacitance storage, equivalent to 1.32e ^- charge/transfer per molecule, resulting in a capacity equ
