Abstract
High capacity layered Li[Lix(Ni0.3Co0.1Mn0.6)1-x]O2 (x = 0.11) cathode and high voltage Li4Ti5O12 spinel anode for the full cell systems have been studied. With combined this cathode and anode materials in an advanced lithium ion battery, a new electrochemical reaction has been demonstrated. It exhibited the initial discharge capacity of 173mAhg-1 and also was maintained at the average specific capacity of 170mAh/g and more than 90% capacity retention. In addition, the battery can cycle at C/10 up to 30 cycles with a very stable capacity delivery. Taking an average voltage of 2.5 V, a specific energy density value of 400Wh/kg was obtained. These environmentally benign Mn-rich layered cathode and spinel Li4Ti5O12 anode materials are going to be future electrodes for Li-ion rechargeable batteries in hybrid electric vehicle applications.
