In this study, LiCoO2 (LCO) material was successfully synthesized in two steps including the fabrication of Co(OH)2 using CoCl2 and NaOH precursors, followed by high-temperature calcination of LiOH and Co(OH)2 synthesized material. X-ray diffraction and scanning electron microscopy were used to evaluate the properties of the synthesized material. The LiCoO2 phase was demonstrated to be present in the LCO material, with a polygonal plate shape of several hundred nanometers in size and tens of nanometers in thickness. When used as a cathode material in lithium-ion batteries, this material exhibited impressive first-cycle capacity, with discharge and charge specific capacities of 122.2 and 140.2 mAh g-1 at 0.2 C, respectively. After 100 cycles, the LCO electrode maintained about 47.8% of the discharge capacity value compared to the first cycle. To demonstrate the feasibility of a full-cell configuration, the synthesized LCO cathode was paired with a Bi2O3@NaBi(MoO4)2 anode. This full-cell system exhibited promising electrochemical behavior, including stable cycling performance and high-rate capacity, indicating its potential application in advanced lithium-ion battery systems.
