摘要：

Driven by theory calculations, we design and synthesized the conjugated polycopper phthalocyanine (CuPPc) by easy hydrothermal method with 1, 2, 4, 5-Tetracyanobenzene (TCNB) as the raw material and then investigated its electrochemical properties as the anode-active material of lithium ion batteries (LIBs). Benefitting from the conjugated microporous structure of CuPPc, it shows good electrochemical properties, including high initial capacity (1376.7 mAh/g at 0.05 A/g) and long-term cycle life (515.9 mAh/g after 200 cycles at 0.5 A/g). This work presents a new strategy to explore high-performance organic anode materials for advanced rechargeable batteries.
