Description
Summary:In this study, lithium terephthalate by solvothermal method with low energy consumption and simple preparation process were synthesized. To obtain the lithium terephthalate with best electrochemical properties, the effects of different organic solvents, reaction temperature and lithium source were investigated and compared. The electrochemical performance of lithium terephthalate prepared from various processing methods as lithium ion battery was furtherly analyzed and discussed. The compositions lithium terephthalate of were confirmed by XRD and FTIR, the morphologies were observed by SEM, and the electrochemical properties were analyzed by cycle charge-discharge tests. The results show that the first discharge capacity of the battery prepared by lithium hydroxide in DMF at a reaction temperature of 175 °C presented the best performance, reaching a maximum capacity of 235/74 mA⋅h/g.
