Fe3C-doped asymmetric porous carbon membrane binder-free integrated materials as high performance anodes of lithium-ion batteries

In traditional pulverous electrodes, the severe volume expansion that occurs during the intercalation and de-intercalation of lithium ions causes the active material to agglomerate and pulverize, eventually leading to active material that deviates from the current collector and result in poor electrochemical performances. Therefore, a new kind of Fe3C-doped asymmetric porous carbon membrane (Fe3C/APCM) binder-free integrated electrode materials …
