Quinones with their structural diversity and electrochemical reversibility are among the most promising organic electrode materials. One distinct feature of quinones is their cross-conjugated structure, the importance of which in the design of organic electrode materials is so far overlooked. Here we report the design, synthesis, and characterizations of two cross-conjugated quinone oligomers (PBDTD and PBDTDS) and their nanocomposites with carbon nanotubes as potential low-cost organic electrode materials for Li-ion batteries. We investigate the effect of conjugation structure and molecular conformations (planar vs. helical) on electrochemical properties such as electronic conductivity, ionic conductivity, and electrode kinetics. Both quinones deliver similar specific capacity over 200 mA h g^–1 at 2.5 V versus Li/Li⁺ with excellent stability over 250 cycles. In particular, the difference in their rate performance is mainly determined by two aspects. First, cross-conjugation of PBDTD becomes electron transport-favorable through-conjugation after reduction, while PBDTDS is always cross-conjugated. Second, the planar conformation of PBDTD facilitates electron-transfer compared with the helical PBDTDS. This work provides insights into the popular yet less understood cross-conjugated quinone-based electrode materials and will stimulate the design of better quinone materials to achieve high-performance organic batteries.
