Summary: This study investigated the impact of PI structure on the electrochemical performance of carbon-coated LTO and found that introducing rigid p-PDA units can improve the molecular arrangement of PI, resulting in a more regular graphite structure with fewer defects and higher conductivity. As a result, the carbon-coated LTO exhibited better rate performance with a discharge capacity of 137.5 mAh/g at 20 C, nearly 1.5 times larger than that of bare LTO (94.4 mAh/g).
