As the&nbsp;use of&nbsp;HV&nbsp;popularizes around the&nbsp;world, there will be a&nbsp;huge amount of End-of-Life HV in the&nbsp;near future, and&nbsp;the&nbsp;proper treatment of&nbsp;these End-of-Life HVs, especially the&nbsp;waste NiMH (Nickel-Metal Hydride) batteries, will become a&nbsp;serious problem. Currently, the&nbsp;recycling of&nbsp;NiMH battery is gaining substantial attention. However, instead of&nbsp;recycling waste NiMH batteries directly, regenerating and&nbsp;reusing a&nbsp;used NiMH battery for a&nbsp;secondhand HV will largely reduce waste battery generation and&nbsp;demand for new NiMH battery. However, the&nbsp;environmental impact of&nbsp;regenerating and&nbsp;reusing a&nbsp;waste NiMH battery was not clear and&nbsp;has&nbsp;not been compared with the situation when using a&nbsp;brand-new NiMH battery. The&nbsp;purpose of&nbsp;this research is to&nbsp;compare the&nbsp;environmental performance (CO2&nbsp;emission) of&nbsp;regenerated NiMH battery and&nbsp;brand-new NiMH battery in an HV from their production to&nbsp;usage stage and&nbsp;to&nbsp;discuss the&nbsp;validity of&nbsp;using a&nbsp;regenerated NiMH in Japan and&nbsp;in other countries using the Life-Cycle Assessment (LCA) approach. This research analyzed the&nbsp;composition of a&nbsp;NiMH battery and&nbsp;the&nbsp;CO2 emission during the manufacture, transportation, regeneration and&nbsp;usage process of a&nbsp;NiMH battery. The&nbsp;data used in this research was collected from reports and&nbsp;data published by the&nbsp;government of Japan, vehicle makers and&nbsp;previous studies. Original field survey and&nbsp;interview research on&nbsp;battery regeneration operators were also performed. The&nbsp;result showed that there is&nbsp;not a&nbsp;big difference in environmental effect. Moreover, by doing so, a&nbsp;huge amount of&nbsp;resource will be saved from battery manufacturing process while reducing waste generation. It is recommended that waste NiMH battery should be regenerated and&nbsp;reused in HV instead of&nbsp;being recycled directly in the&nbsp;future.</p> ER -
