However, two challenges persist: rapid capacity degradation because of low conductivity and hindered ion intercalation pathways due to entanglements of polymer. This work presents a novel copolymer design of thiophene/butylthiophene (TH/BT) blocks integrated with multiwalled carbon nanotubes (MWCNTs). The rigid TH blocks enhance molecular crystallinity to expose electrochemically active thiophene rings, while the flexible BT segments promote the growth of copolymers around MWCNTs to establish an efficient 3D electron transport network. Through optimizing TH:BT ratio to 3:1, the balance between crystallinity and solubility is achieved and yields a block copolymer composite, designated as Cob(3:1)-TH+BT@CNT. Consequently, the anode shows superior performances: 1) enhances reversible capacity of 920 mAh g<sup>-</sup> <sup>1</sup> at 100 mA g<sup>-</sup> <sup>1</sup> (only 300 mAh g<sup>-1</sup> for unmodified polythiophene@CNT); 2) maintains 105.0% and 100.6% capacity after 500 cycles at 1 and 2 A g<sup>-</sup> <sup>1</sup>, respectively; and 3) preserves storage characteristics of thiophene rings near 0.2 V with an excellent rate performance.

Under optimized conditions, an impressive yield of 84.9% and selectivity of 89.9% are achieved, using aqueous ammonia as the nitrogen source and molecular oxygen as the oxidant.
