Outline of Final Research Achievements

There are some issues to be solved before the Next-Generation Vehicles’ popularization around the world, and the need for establishing a new recycling system. Moreover, although advanced countries are exporting a vast amount of used NGV to developing countries, since part of developing countries lacks proper recycling policy and technology. This research assesses and compared the environmental impact of reconditioned NiMH and brand-new NiMH battery, and there is no significant difference when a Hybrid Vehicle uses the former one or the latter. Therefore, not only the recycling of waste NiMH battery from the HV, but also the reuse as a reconditioned NiMH battery into the HV or as a stationary battery should be recommended.
In fact, an effective End-of-Life NiMH battery utilization model will not only help to solve environmental problems, but it will also improve the quality of nomad’s life, international resource recycling for the achievement of the sustainable development goals.
