<p>The prismatic lithium-ion batteries of LiCo1/3Ni1/3Mn1/3O2 with graphite were fabricated and examined in terms of the rate capability, low-temperature discharge characteristics, cycleability, and safety inspection by an accelerating rate calorimeter (ARC). Electricity of 94.0% or 88.2% was delivered at 1 C or 2 C-rate, respectively, against the nominal capacity of 640 mAh determined at 0.2 C-rate at 23°C. When the cells were operated at 0°, −10° or −20°C, the cells respectively delivered 89.5%, 84.9% or 66.5% of electricity based on the capacity determined at 1 C-rate at 23°C. The ARC results on the charged LiCo1/3Ni1/3Mn1/3O2 prepared at 4.4 and 4.7 V in the lithium-ion batteries with graphite indicated that self-heating began at about 160°C and then its heating rate reach maximum at 200°C for charged sample at 4.4 V or 195°C for that at 4.7 V. From these results, we have discussed whether or not novel lithium-ion batteries of LiCo1/3Ni1/3Mn1/3O2 with graphite can be used toward an expanded need for advanced lithium-ion batteries.</p>
