Fe3O4-modified FeCl3/graphite intercalation compound confinement architecture for unleashing the high-performance anode potential of lithium-ion batteries

For the Fe 3 O 4 -modified FeCl 3 /graphite intercalation compound, Fe 3 O 4 is located at the edge of the carbon layer and forms a confined structure with the 2D carbon layer to prevent chlorides from dissolving and shutting, improving the cycle stability.
