The invention discloses an annealing method of a Fe1+yTe1-xSex superconducting strip. The annealing method comprises the following steps: (1) preparing a Fe1+yTe1-xSex strip; (2) immersing the Fe1+yTe1-xSex strip into ionic liquid, heating and preserving heat; and (3) filtering and cleaning the Fe1+yTe1-xSex strip to obtain the annealed Fe1+yTe1-xSex strip. According to the method, the Fe1+yTe1-xSex strip is annealed by adopting the ionic liquid, the cost is low, the process is simple, the quality of the annealedFe1+yTe1-xSex superconducting strip is high, and the process is suitable for large-scale application. 本发明公开了一种Fe1+yTe1-xSex超导带材的退火方法，包括如下步骤：(1)制备Fe1+yTe1-xSex带材；(2)将Fe1+yTe1-xSex带材浸入离子液体中，加热并保温；(3)过滤并清洗Fe1+yTe1-xSex带材，得到退火后的Fe1+yTe1-xSex带材。该方法采用离子液体对Fe1+yTe1-xSex带材进行退火处理，成本低廉、工艺简单，退火后的Fe1+yTe1-xSex超导带材质量高，该工艺适合于规模化应用。
