    storage for lithium-ion batteries

## Description

- description: "In this study, the (TiNb2O7) TNO and modified (Li4Ti5O12) LTO composites
    with the\r\ncore–shell (CS) structures have been designed and prepared by the
    spry-dried\r\nmethod. In the structural composite, the modified LTO core can stabilize
    the\r\ndimensional stability with excellent rate capability, and the TNO shell
    can offer a larger\r\ncapacity, leading to high-performance anode materials. Our
    results indicate that the CS\r\ncomposites without the TNO nanoparticles (NPs)
    aggregation reveal a more negligible\r\nelectrochemical polarization (EP) with
    improved kinetics than traditional composites.\r\nThe optimal TNO content in the
    CS composite is 30 wt%, which can show a larger\r\ncapacity than that of bare
    LTO, with the C-rate ranging between 0.1 and 20 C. It\r\ndelivers a capacity of
    164.9 mA h g-1 at 6 C, higher than bare LTO (157.6 mA h g-1)\r\nand traditional
    composite (154.6 mA h g-1). Furthermore, the full lithium-ion battery\r\n(LIB)
    is fabricated using the CS composite as the anode and LiNi0.5Mn1.5O4 (LNMO)\r\nas
    the cathode. The designed LIB shows an improved energy density of 122.0 W h kg-\r\n1
    with remarkable cycling stability."
