The state and dynamic behaviour of the Li+ ions in Li1+2.Ti2-x.Mgx P3O12 fast ionic conductor system have been investigated with 7Li solid-state NMR techniques. Two activation energy of Li+ ions motion in the different temperature range and two mangnetic inequlvalent Li nuclei are indentified from NMR results. The mechanism of Li+ ions transport in this system are discussed based on the temperatures dependence of Li NMR line shape and 7Li nucleus spin-lattice relaxation time T1.
