A viologen compound is a crystalline compound including a heterocyclic moiety in which a carboxylate of an alkali metal is bound directly or indirectly to both ends of a basic skeleton containing 4,4□-bipyridinium and an anionic moiety that pairs with 4,4□-bipyridinium. The viologen compound can be used, for example, as a negative electrode active material for an electricity storage device including a negative electrode containing the negative electrode active material, a positive electrode containing a positive electrode active material capable of giving and receiving anions, and an ion-conducting medium that is disposed between the positive electrode and the negative electrode and conducts anions.
一种紫罗兰素化合物是一种结晶化合物,其中包括一个杂环基团,该基团中碱金属的羧酸盐直接或间接地与含有4,4□-联吡啶和与4,4□-联吡啶配对的阴离子基团的基本骨架的两端结合。该紫罗兰素化合物可以用作负极活性材料,例如用于包括负极活性材料的负极、包含能够给予和接收阴离子的正极活性材料的正极,以及设置在正极和负极之间并导电阴离子的离子导电介质的电池储能装置的负极。
