目的 探究承印材料和添加单层或少层Mxene(SL Mxene)对柔性锌空电池性能的影响，以及在不同氧气含量环境下的表现。方法 利用丝网印刷在不同承印基材上制备柔性锌空电池，研究承印材料对柔性锌空电池放电性能的影响。结果 得到了在PE防水膜上印刷的柔性锌空电池放电性能最佳，初始开路电压最高，达到5.5 V。在此基础上，探究SL MXene的质量分数对电池放电性能的影响。利用HCl与HF混合溶液对Ti3AlC2进行刻蚀，并剥离得到SL MXene，将SL MXene加入空气电极油墨中，发现SL MXene添加量超过2%时，柔性锌空电池的放电电压保持平稳，放电电压不再改变，并且在弯折时电池的放电电压保持平稳;弯折200次后，电池的放电电压保持96%以上。结论 改变柔性锌空电池所处环境中的氧气含量时，其放电电压表现出与氧气含量呈正相关的特性，表明其在氧气智能包装领域具有应用潜力。

The work aims to investigate the effect of substrate materials and the addition of single-layer MXene (SL MXene) on the performance of flexible zinc-air batteries, as well as the battery performance in environments with different oxygen contents. Flexible zinc-air batteries were prepared on different substrate materials through screen printing. The effect of substrate materials on the discharge performance of flexible zinc-air batteries was studied. It was found that the discharge performance was the best for batteries printed on PE waterproof film, with the highest initial open-circuit voltage reaching 5.5V. Based on this, the effect of the mass fraction of SL MXene on the battery discharge performance was investigated. SL MXene of a single layer or few layers was obtained by etching and peeling Ti3AlC2 using a mixed solution of HCl and HF. When SL MXene was added to the air electrode ink, it was found that the discharge voltage of the flexible zinc-air battery remained stable when the SL MXene addition exceeded 2%, with no further changes. The discharge voltage also remained stable during bending. And after 200 bending cycles, the discharge voltage remained above 96%. When the oxygen content in the environment of the flexible zinc-air battery varies, its discharge voltage shows a positive correlation with the oxygen content, indicating its potential application in the field of oxygen smart packaging.
