Webcris.vub.be WebIn respect of the ion insertions, the negative adsorption energies of Na + into PEDOT and LDH indicate the occurring of ion embedding [54, 55]. The lower value of LDH-insert (−1.1 eV) than that of PEDOT-insert (−0.6 eV) implies that Na + prefers to inert into the interlayers of NiCo-LDH with a smaller embedding potential.
