摘要：

The thermal behaviour of chemically deintercalated samples obtained by HCl treatment of non-stoichiometric Li/Ni mixed oxides is studied. A multi-step reduction of Ni with O2 evolution is observed between room temperature and 800-degrees-C. Two cation redistribution processes are shown by the exothermal occurrence of a spinel phase at 300-degrees-C and the endothermal reduction to a rock-salt phase with random distribution of Li and Ni cations in octahedral sites at 800-degrees-C.
