The substituent effect on the redox potential of lithium terephthalate was studied using symmetrical dilithium disubstituted-terephthalates incorporating bromo, methoxy and amino groups. All the terephthalate derivatives have been synthesized and evaluated as anode material for lithium-ion batteries. The electrochemical results revealed an increase in the reduction potential in the case of bromo and methoxy groups and almost the same in the case of amino group compared to unmodified dilithium terephthalate. In addition, a very first tendency between the 13C chemical shifts and FTIR signal of the carbonyl and the reduction potential of the studied disubstituted-terephthalates was formulated.

取代基对对苯二甲酸酯类锂电池电极材料氧化还原电势的影响
使用结合了溴,甲氧基和氨基的对称二取代对苯二甲酸二锂盐研究了取代基对对苯二甲酸锂氧化还原电势的影响。所有对苯二甲酸酯衍生物均已合成并评估为锂离子电池的负极材料。电化学结果表明,与未改性的对苯二甲酸二锂相比,在溴和甲氧基的情况下,还原电势增加,而在氨基的情况下,还原电势几乎相同。此外,在羰基的13 C化学位移和FTIR信号与所研究的双取代对苯二甲酸酯的还原电位之间建立了第一个趋势。
