The LiNi1/3Co1/3Mn1/3O2 electrode material was prepared via a carbon gel-combustion process using resorcinol-formaldehyde gel as fuel and nitrate as an oxidizer. The carbon gel process ensures the molecular-level homogeneity of the chemical product. The gas derived from carbon gel separates the raw material particles and restrains the growth of the grains to some extent, and well-crystallized nanosized powders are obtained with calcination at 700 degrees C for 6 h. As the cathode material for lithium-ion batteries, the discharge capacity of LiNi1/3Co1/3Mn1/3O2 was as high as 175.6 mA h g(-1) in the first cycle at 0.5 C, and it could remain 163.0 mA h g(-1) within the voltage range of 2.5-4.4 V after 50 cycles. The electrode also showed outstanding rate capacities at high discharge rates such as 30 C and 50 C, suggesting the applications of the material in high power lithium-ion batteries.
