In this article, we describe the design and gram-scale synthesis of a new anthracene-based negative electrode material for Li-ion batteries. Based on rational design, featuring a strong electronic delocalization and a long conjugation length, this material has power performance to date unmatched for a conjugated lithium carboxylate, displaying a gravimetric capacity of 150 mAh g-1 at a cycling rate
在本文中,我们描述了一种用于锂离子电池的新型蒽基负极材料的设计和克级合成。基于合理的设计,具有强大的电子离域能力和长的共轭长度,该材料迄今为止具有共轭羧酸锂无法比拟的功率性能,在20 Li + / h的循环速率下显示出150 mAh g-1的重量容量( 10 C),无需任何电极工程。另外,对于设计,完全还原相的部分溶解度也可以解释以低速和高速获得的电化学性能。
