Fig. 5: Degradation of Li+ diffusion kinetics induced by protons.
From: Proton-exchange induced reactivity in layered oxides for lithium-ion batteries

a, b The voltage profiles of protonated (W-NCM) and relithiated (R-NCM) materials, as well as commercial materials (C-NCM) in the voltage range of 3-4.3 V. c deduced diffusion coefficients of protonated and relithiated materials. d The pathway of Li+ migration in protonated NCM111. e Selected calculated Li+ migration barrier in pristine and protonated NCM111 with proton absorbed onto different O atoms.
