摘　　要：目的探究承印材料和添加单层或少层Mxene(SLMxene)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5.5V。在此基础上,探究SLMXene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Ti_(3)AlC_(2)进行刻蚀,并剥离得到SLMXene,将SLMXene加入空气电极油墨中,发现SLMXene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 Ti_(3)AlC_(2) 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.
