Recently, used batteries are causing an environmental contamination and a waste of limited resources with increasing demand of portable secondary batteries in market. In developed countries, their governments have legally required the manufacture to collect and recycle the used batteries, so the related companies have formed an organization for collecting the used batteries and they are effectively recycling them.

Therefore, we need an effective measure to ensure the recycling of the used batteries as soon as possible.
