Sustainable and environment-friendly rechargeable devices are required to meet increasing electrical energy demands. Organic batteries are fabricated using organic redox materials which are potentially synthesised from earth-abundant components. However, to avoid plastic pollution, these organic materials must display sufficient functions and ensure safe management post-utilisation. This study demonstrated a sustainable and environment-friendly recycling method for functional organic materials developed using organic redox molecules. These molecules could be prepared from earth-abundant and sustainable raw chemicals via environment-friendly preparation routes. The eco-friendly battery, which uses organic redox molecules as anode- and cathode-active materials and neutral aqueous solution as an electrolyte, exhibited high cyclability (>95 % capacity after 100 cycles) and high-rate capability (15 C). After use, the electrode-active material was separated and/or decomposed to the original raw chemicals, demonstrating a green and sustainable option to use conventional organic redox materials.
为满足不断增长的电能需求，需要可持续且环保的可充电设备。有机电池是使用有机氧化还原材料制造的，这些材料有可能由地球上储量丰富的成分合成。然而，为避免塑料污染，这些有机材料必须具备足够的功能，并确保使用后能安全管理。本研究展示了一种针对使用有机氧化还原分子开发的功能性有机材料的可持续且环保的回收方法。这些分子可以通过环保的制备路线，由地球上储量丰富且可持续的原始化学品制备而成。这种使用有机氧化还原分子作为阳极和阴极活性材料、中性水溶液作为电解质的环保电池，表现出高循环稳定性（100次循环后容量>95%）和高倍率性能（15C）。使用后，电极活性材料被分离和/或分解为原始的原始化学品，这展示了一种使用传统有机氧化还原材料的绿色且可持续的选择。
