Foam-like CoO@N,S-codoped carbon composites derived from a well-designed N,S-rich Co-MOF for lithium-ion batteries

A novel 4-fold interpenetrated dia MOF was used as a N,S-containing precursor to fabricate a foam-like CoO@N,S-codoped carbon hybrid composite via pyrolysis at 550 °C under an Ar atmosphere. The foam-like CoO@N,S–C exhibited excellent electrochemical properties as anode materials for LIBs.
