Synthesis and electrochemical performance of Li and Ni 1,4,5,8-naphthalenetetracarboxylates as anodes for Li-ion batteries

Metal-1,4,5,8-naphthalenetetracarboxylates (Metal = Li and/or Ni) were synthesized and investigated as anode materials for lithium ion batteries. These complexes were characterized by Fourier transform infrared spectroscopy, X-ray diffraction and thermogravimetry. Electrochemical tests indicated that these materials exhibited superior electrochemical performance and good cycling stability.

► Metal-naphthalenetetracarboxylates (M-NTC, M = Li and/or Ni) were synthesized via a rheological phase reaction.
► These complexes were investigated as anode material for lithium ion batteries.
► Li/Ni-NTC composite shows both high capacity and good cycling stability compared with Li-NTC and Ni-NTC.
