英文摘要	Li(Ni1/3Co1/3Mn1/3)O-2 microspheres with a tap density of 2.41 g cm(-3) have been synthesized for applications in high power and high energy systems, using a simple theological phase reaction route. Cyclic voltammograms (CV) showed no shift of anodic and cathodic peaks centred at 3.81, 3.69 V for the Ni2+/Ni4+ Couple after first cycle. The results of power pulse area specific impedance (ASI) and differential scanning calorimetry (DSC) tests showed lower power impedance and increased thermal stability of the electrode at high rate. These merits mentioned above provided significant improved capacity and rate performance for Li(Ni1/3Co1/3Mn1/3)O-2 microspheres, which 159, 147 mAh g(-1) discharge capacity was delivered after 100 cycles between 2.5-4.6 V vs. Li at a different discharge rate of 2.5 C (500 mA g(-1)), 5 C and a constant 0.5 C charge rate, respectively.
