摘要

Magnetite (Fe3O4) has a large theoretical reversible capacity and rich Earth abundance, making it a promising anode material for LIBs. However, it suffers from drastic volume changes during the lithiation process, which lead to poor cycle stability and low-rate performance. Taking inspiration from how plant cells mitigate excessive water uptake/loss through their cell walls to preserve the structural integrity of cells, in this work Fe3O4@PMMA multicore capsules were designed as a kind of anode material inhibiting volume expansion to promote industrial applications.
