  <dc:description xmlns:ns0="xml" ns0:lang="en">Natrium super ionic conductor (NASICON) materials providing attractive  properties such as high ionic conductivity and good structural stability are  considered as very promising materials for use as electrodes for lithium- and  sodium-ion batteries. Herein, a new high-performance electrode material,  Li0.5Ni0.5Ti1.5Fe0.5(PO4)3/C, was synthesized via the sol–gel method and  was electrochemically tested as an anode for lithium ion batteries, providing  enhanced electrochemical performance as a result of nickel substitution into the  lithium site in the LiTi2(PO4)3 family of materials. The synthesized material  showed good ionic conductivity, excellent structural stability, stable long-term  cycling performance, and improved high rate cycling performance compared to  LiTi2(PO4)3. The Li0.5Ni0.5Ti1.5Fe0.5(PO4)3/C electrode delivered reversible  capacities of about 93 and 68% of its theoretical one at current rates of 0.1 C  (6.42 mA·g–1) after 100 cycles and 5 C (320.93 mA·g–1) after 1000 cycles,  respectively. Theoretically, three Li+ ions can be inserted into the vacancies of  the Li0.5Ni0.5Ti1.5Fe0.5(PO4)3/C structure. However, when the electrode is  discharged to 0.5 V, more than three Li+ ions are inserted into the NASICON  structure, leading to its structural transformation, and thus to an irreversible  electrochemical behavior after the first discharge process.</dc:description>
