摘要: Li4Ti5O12 typically shows a flat charge/discharge curve, which usually leads to difficulty in the voltage-based state of charge (SOC) estimation. In this study, facile quench-assisted solid-state method is used prepare highly crystalline binary Li4Ti5O12-Li2Ti3O7 nanocomposite. While exhibits sudden voltage rise/drop near end its nanocomposite has tunable sloped profile. The unique lamellar morphology consisting interconnected nanograins ≈20 nm size with hierarchical nanoporous structure, contributing an enhanced rate capability capacity 128 mA h g−1 at high C-rate 10 C, and excellent cycling stability.
