摘要

Nanoporous Li4Ti5O12 (N-LTO) was prepared by sol-gel method using monodisperse polystyrene spheres as a template and followed by calcination process. The as-prepared N-LTO has a spinel structure, large special surface area, and nanoporous structure with the pore average diameter of about 100 nm and wall thickness of 50 nm. Electrochemical experiments show that N-LTO exhibits a high initial discharge capacity of 189 mAh g(-1) at 0.1 C rate cycled between 0.5 and 3.0 V and excellent capacity retention of 170 mAh g(-1) after 100 cycles. EIS and CV analysis show that N-LTO has a higher mobility for Li+ diffusion and a higher exchange current density, indicating an improved electrochemical performance. It is believed that the nanoporous structure has a larger electrode/electrolyte contact area, resulting in better electrochemical properties at high charge/discharge rates.
