Abstract The influence of the lithium content in the starting composition, depth of discharge, binder and electrolyte on the cycle stability was investigated. The structural changes in Li x (Al 0.8 Zn 0.2 ) electrodes during electrochemical lithium extraction and reinsertion were studied by in situ synchrotron diffraction. The crystal structure of the new compound Li 4 Al 3.42 Zn 11.58 was determined by single-crystal X-ray diffraction and can be described as combination of the CaCu 5 and MgFe 6 Ge 6 structure types. The phase equilibria at 150 °C in the Li–Al–Zn system were investigated on six alloys, prepared along the lithium extraction–insertion line.
