Figure 1. (A) SEM image and EDS mapping results (elements Al, Fe, P, C, O) of LMC@3_1 electrode with LFP and MC as active materials. (B) Schematic illustration of the establishment of local Li⁺-rich region around MC, contributing to the fast Li-intercalation kinetics of LFP nanoparticles. (C) Voltage curves of LMC@3_1 cathode under 1C charge/discharge, the corresponding capacitive behavior ($$ \mathrm{PF}_{6}^{-} / \mathrm{Li}^{+} $$ adsorption/desorption) and Faraday behavior (Li⁺ extraction/intercalation) in different regions were marked. (D) Specific capacity of MC and the Li⁺-rich concentration range by MC addition at various current densities.
