The design and fabrication of high‐performance all‐plastic batteries is essentially important to achieve future flexible electronics. A major challenge in this field is the lack of stable and reliable soft organic electrodes with satisfactory performance. Here, a novel all‐plastic‐electrode based Li‐ion battery with a single flexible bi‐functional ladderized heterocyclic poly(quinone), (C₆O₂S₂)_n, as both cathode and anode is demonstrated. Benefiting from its unique ladder‐like quinone and dithioether structure, the as‐prepared polymer cathode shows a high energy density of 624 Wh kg⁻¹ (vs lithium anode) and a stable battery life of 1000 cycles. Moreover, the as‐fabricated symmetric full‐battery delivers a large capacity of 249 mAh g⁻¹ (at 20 mA g⁻¹), a good capacity retention of 119 mAh g⁻¹ after 250 cycles (at 1.0 A g⁻¹) and a noteworthy energy density up to 276 Wh kg⁻¹. The superior performance of poly(2,3‐dithiino‐1,4‐benzoquinone)‐based electrode rivals most of the state‐of‐the‐art demonstrations on organic‐based metal‐ion shuttling batteries. The study provides an effective strategy to develop stable bi‐functional electrode materials toward the next‐generation of high performance all‐plastic batteries.

迈向具有单一有机聚合物作为阴极和阳极的高性能全塑料充满电池

高性能全塑电池的设计和制造对于实现未来的柔性电子产品至关重要。在该领域中的主要挑战是缺乏具有令人满意的性能的稳定和可靠的软有机电极。在这里，展示了一种新颖的基于全塑料电极的锂离子电池，该电池具有单个柔性双功能梯形杂环聚（醌）（C ₆ O ₂ S ₂）_n，同时作为阴极和阳极。得益于其独特的梯状醌和二硫醚结构，所制得的聚合物阴极显示出624 Wh kg ^-1的高能量密度（相对于锂阳极）和1000次循环的稳定电池寿命。此外，预制的对称式全电池可提供249 mAh g ^-1的大容量（在20 mA g ^-1时），经过250次循环（在1.0 A g ^-1时）具有119 mAh g ^-1的良好容量保持率。并且值得注意的能量密度高达276 Wh kg ^-1。聚（2,3-二噻吩并-1,4-苯醌）电极的卓越性能可与大多数有机金属离子穿梭电池的最新演示相媲美。这项研究提供了一种有效的策略，可以为下一代高性能全塑料电池开发稳定的双功能电极材料。
