[en] ABSTRACT: Spinel Li₄Ti₅O₁₂ has been thought as one of ideal anode materials for Li ion batteries due to its safety performance and long cycle life, while the low conductivity and Li-ion diffusion capability has limited its application. To improve the electrochemical performance of Li₄Ti₅O₁₂, Gd-doped single-crystalline Li₄Ti₅O₁₂/TiO₂ (rutile phase) nanosheets composites in this study was prepared via a solvothermal synthesis assisted method. It is found that the as prepared doped dual phases composites showed superior electrochemical performance as anode material. At a current density of 0.2 A/g (1.14 C), the Gd-LTO/TiO₂ electrode can deliver a specific capacity of ∼180.2 mAh/g, and it can deliver a specific capacity as high as ∼111.1 mAh/g even at current density of 20 A/g (114.3 C). The introduction of Gd ion has been found to play a crucial role in improving the electrochemical performance, and its introduction modifies the morphology of as prepared sample at the same time.
