Sonication-induced Electrostatic Assembly of FeCO3@Ti3C2 Nanocomposite for Robust Lithium Storage

Abstract

Moreover, the practical application of FeCO3 NR@Ti3C2 anode material is further primarily evaluated by coupling with a commercial Ni-rich LiNi0.8Co0.1Mn0.1O2 (marked as NCM811) cathode material. SEM image of NCM811 particles is presented in Figure S13a, together with charge/discharge curves at 20 mA g-1 in a voltage range of 2.7-4.3 V vs. Li+/Li (Figure S13b) and cycling performance at 200 mA g-1 after two cycles at 20 mA g-1 (Figure S13c). Figure S13d shows charge/discharge curves in the first three cycles of the full FeCO3 NR@Ti3C2//NCM811 cell cycled at 200 mA g-1 in a tentative voltage range of 0.5-3.9 V, which can deliver specific capacity of approximately 150 mAh g-1 with desired cycling stability (Figure S13e). Overall, the FeCO3 NR@Ti3C2 composite material has been demonstrated as a promising anode alterative for high-energy lithium ion batteries.
