Characterization of Li 1-xNi 1+xO 2 prepared using succinic acid as a complexing agent
Li1-xNi1+xO2was prepared by a polymerized complex method using succinic acid as a complexing agent. Ethanolic solutions of lithium acetate dihydrate, nickel acetate tetrahydrate, and succinic acid were mixed to form carboxylate precursors, which were subsequently calcined at 650-800°C for 14-48 h.

| Summary: | Li1-xNi1+xO2was prepared by a polymerized complex method using succinic acid as a complexing agent. Ethanolic solutions of lithium acetate dihydrate, nickel acetate tetrahydrate, and succinic acid were mixed to form carboxylate precursors, which were subsequently calcined at 650-800°C for 14-48 h. TGA curves of metal acetates, succinic acid, and the precursors were characterized to determine weight loss and formation temperature of the oxide. By using XRD, SEM, and EDX, pure crystals of Li1-xNi1+xO2were detected at 750 and 800°C. The maximum and minimum intensity ratios of XRD spectra show that the optimum calcination condition is 750°C for 40 h. At 650-800°C, the particle size distribution is in the range of 0.35-39 μm. © Pleiades Publishing, Inc., 2006. |
