汰役電池變更用途使用是指將退役的電池產品，經過簡單篩選與處理之後可再次使用，這種方式比經由複雜流程所回收的內部材料更環保且具有更高的經濟利益。 本計畫從能夠再利用的3種電池芯中，分別挑選20個電池芯（共60個電池芯）做預循環特性測試，另外在沒有這些電池芯的原始規格特性的情況下，本案參考UL1974的電池檢測項目對電池進行測試。並依據測試的結果，藉由我們對電池的基本了解來訂定了分類分級標準，最後從3種預循環特性測試的電池中分別挑選10個電池芯實際的試運行。 試運行的整體結果顯示，15個健康狀況較好的電池有14個具有好的容量維持，其餘1個出現稍微較快的衰退。這表示再利用電池仍然具有良好的容量維持率，因此可說明電池再利用具有可行性，而我們的分類和分組方法雖未能完全預測電池的老化狀況，但已具有一定的準確性。健康狀況較差的電池中有降額使用的6個電池都沒有出現異常的老化，而正常使用的9個電池中有2個電池出現快速的容量衰退，這顯示出我們的分類和分級方法具有成效。 總結而言，由於我國電動汽機車的推動尚屬初期階段，國內鋰電池排出量目前仍有限，但可預期將爆發性排出。建議可參考國際汰役電池相關資源回收及再利用作法及法規架構，除進行如回收率及資源再生等末端回收管理外，更進一步推動上游端管理，著重碳足跡和產品履歷規範，並發展出新興的商業模式，同時需要政府、企業、研究機構和公眾的參與，快速推動汰役電池的回收及再生電池產業，確保建立有效且可永續經營的電池產業生態體系。

The repurpose of retired batteries is to reuse batteries from retired battery products for 2nd use application(s). This approach is more environmentally friendly and economically beneficial compared to retrieve some materials inside the batteries through complicated recycling process. This project conducted pre-cycling characteristic tests on a total of 60 battery cells, selecting 20 cells from three types of reusable battery cells. In addition, without the original specification characteristics of these battery cells, the project referred to the battery testing items in UL1974 to conduct tests on the batteries. Based on the test results and our basic battery knowledge, sorting and grading standards were established. Finally, 10 battery cells were selected from each of the three pre-cycling characteristic tests for trial runs. The overall results of the trial runs showed that out of the 15 healthier battery cells, 14 maintained good capacity, while one showed slightly faster degradation. This indicates that reusing batteries still maintains good capacity retention, making battery reuse feasible. Although our sorting and grouping methods did not fully predict the aging condition of the batteries, however, it still demonstrated a high level of accuracy. Our sorting and grading approach has proven effective as none of the six cells with derated use exhibited abnormal aging, whereas two out of the nine cells with normal use exhibited rapid capacity decline. In conclusion, as the promotion of electric vehicles and motorcycles in Taiwan is still in the early stages, the amount of retired batteries is currently limited, but an explosive increase is anticipated. It is recommended to reference international practices and regulatory frameworks for the recycling and reuse of retired batteries. In addition to implementing end-of-life recycling management, such as recycling rates and resource regeneration, there is a further need to promote upstream management, emphasizing carbon footprint and product traceability specifications, and developing innovative business models. Moreover, the collective involvement of government, businesses, research institutions, and the public is essential to rapidly advance the recycling, reuse and repurpose of retired batteries, ensuring the establishment of an effective and sustainable battery industry ecosystem.
