The conventional Li–O₂ battery (LOB) has hardly been considered as a next-generation flexible electronics thus far, since it is bulk, inflexible and limited by the absence of an adjustable cell configuration. Here, we present a flexible Li–O₂ cell using N-doped carbon nanocages grown onto the carbon textiles (NCNs/CTs) as a self-standing and binder-free O₂ electrode. The highly flexible NCNs/CTs exhibits an excellent mechanic durability, a promising catalytic activity towards the ORR and OER, a considerable cyclability of more than 70 cycles with an overpotential of 0.36 V on the 1^st cycle at a constant current density of 0.2 mA/cm², a good rate capability, a superior reversibility with formation and decomposition of desired Li₂O₂, and a highly electrochemical stability even under stringent bending and twisting conditions. Our work represents a promising progress in the material development and architecture design of O₂ electrode for flexible LOBs.

迄今为止，传统的Li-O ₂电池（LOB）几乎没有被认为是下一代柔性电子产品，因为它体积大，不灵活并且受到缺乏可调节电池单元配置的限制。在这里，我们介绍了一种柔性的Li–O ₂电池，该电池使用生长在碳纤维织物（NCN / CT）上的N掺杂碳纳米笼作为自立且不含粘合剂的O ₂电极。高度灵活NCNs / CTS表现出优异的机械耐久性，朝向ORR和OER有希望的催化活性，与超电势在1个0.36 V的相当大的可循环性超过70个循环的^第一循环以0.2mA的恒定电流密度/厘米²具有良好的倍率性能，所需的Li ₂ O _2的形成和分解具有优异的可逆性，甚至在严格的弯曲和扭曲条件下也具有很高的电化学稳定性。我们的工作代表了用于柔性LOB的O ₂电极的材料开发和架构设计方面的有希望的进展。
