LiCoPO4 was prepared by a citric acid assisted sol-gel method and exploited as cathode material for lithium ion batteries. TG curve showed the appropriate temperature of the reaction and X-ray diffraction patterns indicated that LiCoPO4 synthesized at different temperatures was crystallized in an orthorhombic structure. During charge-discharge cycles, LiCoPO4 presented a plateaus of 4.8V corresponding to Co3+/Co2+ redox couples, and a discharge capacity of 126.3 mAh/g in the first cycle. The CV curve of LiCoPO4 showed that Li-ion diffusion in LiCoPO4 obeyed a different mechanism between charge and discharge processes.

The growth of the lithium-ion battery market is accelerating. Although they are widely used in various fields, ranging from mobile devices to large-capacity energy storage devices, stability has always been a problem, which is a critical disadvantage of lithium-ion batteries. If the battery is unstable, which usually occurs at the end of its life, problems such as overheating and overcurrent during charge-discharge increase. In this paper, we propose a method to accurately predict battery life in order to secure battery stability. Unlike the existing methods, we propose a method of assessing the life of a battery by estimating the irreversible energy from the basic law of entropy using voltage, current, and time in a realistic dimension. The life estimation accuracy using the proposed method was at least 91.6%, and the accuracy was higher than 94% when considering the actual used range. The experimental results proved that the proposed method is a practical and effective method for estimating the life of lithium-ion batteries.
