Synthesis of Defective-Structure Li 4 Mn 5 O 12 by Combustion Method and Its Application to Hybrid Capacitor

2010 
was synthesized by combustion method using , and . was obtained over , however, the sample calcined at for any time was mixed phases of and . calcined at for 5 h had larger first discharge capacity (41.5mAh/g) at 1C-rate for 3.7~4.4V than other calcined samples. Moreover, applying to hybrid capacitor, it had good discharge capacity (24.74 mAh/g or 10.46 mAh/cc) at 100 mA/g for 1~2.5 V and higher energy density (39Wh/kg or 16.49Wh/cc) at same condition.
