## Description

- description: Carbon-coated Li4Ti5O12 (LTO) has been prepared using polyimide (PI)
    as a carbon source via the thermal imidization of polyamic　acid (PAA) followed
    by carbonization process. In this study, the PI with different structures based
    on pyromellitic dianhydride (PMDA), 4,4’-oxydianiline (ODA), and p-phenylenediamine
    (p-PDA) moieties have been synthesized. The effect of the PI structure on the
    electrochemical performance of the carbon-coated LTO has been investigated. The
    results indicate that the molecular arrangement of PI can be improved when the
    rigid p-PDA units are introduced into the PI backbone. The carbons derived from
    the p-PDA based PI show a more regular graphite structure with less amount of
    defects and higher conductivity. As a result, the carbon-coated LTO exhibits a
    better rate performance with a discharge capacity of 137.5 mAh/g at 20 C, which
    is almost 1.5 times larger than that of bare LTO (94.4 mAh/g).
