Spinel compound LiNi(0.4)Mn(1.5)Cr(0.1)O(4) (LNMCO) and Li(4)Ti(5)O(12) (LTO) were synthesized by the sol-gel method and the solid-state method, respectively. The particle sizes of the products LiNi(0.4)Mn(1.5)Cr(0.1)O(4) and Li(4)Ti(5)O(12) were 0.5 to 2 um and 0.5 to 0.8 um, respectively. All samples exhibited excellent electrochemical properties. A LiNi(0.4)Mn(1.5)Cr(0.1)O(4)/Li(4)Ti(5)O(12) (LNMCO/LTO) cell was fabricated and was demonstrated to exhibit good electrochemical properties at the high current rate of 1 C. When the specific capacity was determined based on the mass of the LNMCO cathode, the LNMCO/LTO cell delivered 125 mAh g(-1) at 1 C and 77 mAh g(-1) at 5 C. The capacity retentions after 30 cycles were 94.4 % and 83.1 %, respectively.
