LNCO is a lamellar oxide used as a positive electrode material in Li batteries exhibiting good electrochemical charge-discharge behavior. The high reversibility of the lithium intercalation process, due to the strictly 2D character of the LNCO material, the high cell voltage (but not too high due to the position of the Ni4+/Ni3+ couple vs the Co4+/Co3+ couple), and the presence of a relatively small cobalt content, makes this material a very promising one for lithium battery applications.
