PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery treatment method for safely and quickly rendering the nonaqueous secondary battery harmless.SOLUTION: The nonaqueous secondary battery treatment method is provides that includes: a step (a) of preparing a nonaqueous secondary battery; and a step (b) of adding a redox shuttle agent to the inside of the nonaqueous secondary battery. The redox shuttle agent is a compound showing oxidation-reduction potential in the range of 3.0 to 4.5 V with respect to an oxidation-reduction potential of a metal corresponding to an electrolyte ion of the nonaqueous secondary battery.SELECTED DRAWING: Figure 2 【課題】非水系二次電池を安全かつ迅速に無害化するための非水系二次電池の処理方法を提供する。【解決手段】（ａ）非水系二次電池を用意する工程、及び（ｂ）非水系二次電池の内部にレドックスシャトル剤を添加する工程を含む、非水系二次電池の処理方法であって、レドックスシャトル剤が、非水系二次電池の電解質イオンに対応する金属の酸化還元電位に対して３．０〜４．５Ｖの範囲に酸化還元電位を示す化合物である、上記処理方法。【選択図】図２
