Abstract: Organic polymers have been considered reliable candidates for lithium storage due to their high capacity and lack of volume expansion. Compared with other organic polymers, polyimide has become a very promising electrode material for lithium-ion batteries (LIBs) because of its easy synthesis, customizable structure and structural stability. A large number of studies have confirmed that the benzene ring structure of polyimide has strong lithium storage capacity as an anode material. Hence, we designed and synthesized polyimide organic polymer (PBPAQ) for the first time. The unique spherical flower structure of this material enhances the interaction between the electrode material and the electrolyte by increasing the contact area. The PBPAQ anode has a specific discharge capacity of 738 mAh g <superscript>-1</superscript> after 100 cycles at 0.1 A g <superscript>-1</superscript> . The excellent lithium storage performance of this material laid a foundation for the research of the anode of LIBs in the future.<br /> (© 2023 Wiley-VCH Verlag GmbH.)
