Original Abstract

Extraction of the cathode material from disassembled Samsung 18650 cell with LiCoO2 (LCO) chemistry was performed. The effect of dissolving with industrially used organic solvents is compared with the effect of selected ecological options. In successfully separated powders were studied structural changes as a function of aging and storage time. Ex-situ X-ray diffraction analysis was used for observation of differences between materials separated from cell in a fresh state and aged cell. Phase transition happening in the LiCoO2 material during cycling of the battery but also when in contact with air are discussed. Shift of the main peak (0 0 3) and (1 0 4) for the aged cathode material are displayed and discussed.
