The structural evolution of electrochemically prelithiated Fe2O3 nanoparticles confined in carbon nanotubes (CNTs) during lithium insertion/extraction is studied by in situ transmission electron microscopy. It is found that the aggregation and coarsening of Fe core‐containing Li2O (Fe@Li2O) nanograi...
