Patent ID: 7119517

Claim:
A method of recycling secondary batteries, said method comprising: a first quality control process performed at a first site, said first quality control process including: conducting a first inspection on the secondary batteries; separating the secondary batteries into at least two quality levels based on a result of said first inspection; and classifying the separated secondary batteries into a first group and a second group according to said separating of the secondary batteries into the at least two quality levels; a first reuse process performed on the first group of secondary batteries at the first site, said first reuse process including different ways of processing the first group of secondary batteries to make the first group of secondary batteries reusable according to a quality level of each of the secondary batteries of the first group; a second quality control process performed at a second site, said second quality control process including: conducting a second inspection on the second group of secondary batteries; separating the second group of secondary batteries into at least two quality levels based on a result of said second inspection; and classifying the separated second group of secondary batteries into a third group and a fourth group according to said separating of the second group of secondary batteries into the at least two quality levels; a second reuse process performed on the third group of secondary batteries at the second site, said second reuse process including different ways of processing the third group of secondary batteries to make the third group of secondary batteries reusable according to a quality level of each of the secondary batteries of the third group; and a recycling process performed on the fourth group of secondary batteries at a third site, said recycling process including disassembling the fourth group of secondary batteries to collect useful materials.
