选择均苯四甲酸二酰亚胺二锂盐来完成我们的数据库中的氧化还原活性的聚酮与N-环状结构。尽管迄今为止从未报道过，但这种锂化盐易于合成，使得其在Li电池中的电化学评价成为可能。初步数据表明，这种新型材料在相对较低的电位下每个分子式单元可逆地插入两个Li，得到200 mAh g（-1）的稳定容量值。
Pyromellitic diimide dilithium salt was selected to complete our database on redox-active polyketones with a N-cyclic structure. Although never reported to date, such a lithiated salt was readily synthesized making its electrochemical evaluation in a Li battery possible. Preliminary data show that this novel material reversibly inserts two Li per formula unit at a relatively low potential giving a stable capacity value of 200 mAh g(-1).
