Rational Design of Porous TiO2@N‐Doped Carbon for High Rate Lithium‐Ion Batteries

Considering the merits of natural biomass, a soybean is designed and applied as a green source for N‐doped carbon to fabricate a TiO2@N‐doped carbon (TiO2@NC) composite for lithium‐ion batteries (LIBs). The TiO2 nanoparticles are uniformly anchored on the surface of porous N‐doped carbon frameworks. As anode materials for LIBs, TiO2@NC exhibits excellent cycle performance and enhanced rate capacity. After 100 cycles at 1 C, the capacity can be maintained at 282.2 mAh g−1. In addition, it can even deliver a large reversible capacity of 155 mAh g−1 after 200 cycles at 5 C. These excellent results prove that the designed composite can be applied as a promising anode material for a lithium‐ion storage system with improved electrochemical performances.
