a XRD patterns of Li2Co2O4 as prepared and after OER. The orange line corresponds to the XRD peak of the carbon fiber paper. b Raman spectra of Li2Co2O4 as prepared and after OER. c HAADF-STEM images of as-prepared Li2Co2O4. d HAADF-STEM images of Li2Co2O4 after OER. Both are viewed down the [110] zone axis, and the arrows are along the [1-11] direction.
