A composite of Si nanoparticles and a two dimensional porous conductive Ni3(2,3,6,7,10,11-hexaiminotriphenylene)2 (Ni3(HITP)2) metal–organic framework (MOF), namely Si/Ni3(HITP)2, is suggested as a potential anode material for Li-ion batteries.
In this study, a self-encapsulated Sb–C nanocomposite as an anode material for sodium-ion batteries (SIBs) was successfully synthesised using an SbCl3–citrate complex precursor, followed by a drying and calcination process under an inert N2 atmosphere.
In this work, we synthesized highly porous 3D sponge‐like mesoporous (MP)‐Si@C composites using mass‐scalable method. The optimized MP−Si@C 1 composite electrode, provided a reversible capacity of 1887 mAh g−1 after 100 discharge−charge cycles with capacity retention of 83 % at the rate of 0.1 C. At high C‐rate the MP−Si@C 1 anode provided reversible capacity of 910 mAh g−1 after 1000 cycles. The MP−Si@C 1/LCO full cell provide a discharge capacity of 1515 mAh g−1 and it works well for 100 cycles. This outstanding electrochemical behavior of the MP−Si@C 1 composite electrode was accredited to the exclusive structure of interconnected Si nanoparticles and the presence of the outer C thin layer. The carbon layer served as a shield, an effective buffer layer to house the extreme volume expansion issue of Si during continuous cycling. The excellent performance of the MP−Si@C 1 composite demonstrated its high applicability as potential anode material for next‐generation LIBs.
