✦ Synopsis

New data on acid delithiation of lithium-nickel oxides, (\mathrm{Li}_{x}) (\mathrm{Ni}_{2-x} \mathrm{O}_{2}(0.60.9) ), where long-range cation order is developed, the extraction of lithium and impurity nickel ions proceeds concomitantly with partial exchange between lithium from the (\mathrm{LiO}_{2})-layers and protons from the acid solution. The different chemical compositions of acid-treated oxides (\mathrm{Li}_{x} \mathrm{Ni}_{2-x} \mathrm{O}_{2}(0.60.9)), dehydration processes also take place. 1994 Academic Press, Inc.
