摘　　要：Organic molecules are attractive electrode materials for rechargeable batteries owing to their sustainability, low cost, and light weight. In this work, we report a new organic anode, a perimidin derivative 1,3,5-tri(1 H-perimidin-2-yl)-benzene(TPB), for lithium-ion batteries. The TPB structure contains multiple redox centers including π-conjugated benzene ring, C=N, and-NH groups and delivers a high reversible specific capacity of 300 mAh/g at 50 mA/g under a six-electron redox reaction. Moreover, TPB exhibits excellent rate capability and long-term cyclability with 98.1% capacity retention over 1500 cycles at 1000 mA/g. The results may open new opportunities for the development of low-cost and long-lifespan lithium-ion batteries.
