Physical treatment of lithium primary batteries without explosion is required to recycle the lithium primary batteries which could be exploded by heating too much or crushing. The safe dismantlement method of the spent lithium primary batteries has been required to recycle the batteries because the batteries contain lithium metal although the batteries are discharged. In the present study, safe dismantlement of the spent batteries was investigated, and then feasibility study was performed to recycle scraps of the spent batteries. As written above, the batteries were safely crushed, and metals such as nickel were recovered. Further study was required to increase recovery ratio and purity of metal.
