Ultimately, rigorous studies on battery lifespan coupled with the adoption of holistic strategies will markedly advance the reliability and stability of battery technologies, forming a robust groundwork for the progression of the energy storage sector in the future. 3. Necessity and data source of early-stage prediction of battery life 3.1.
The remaining battery lifetime information is also critical for battery second-life applications. This paper provides a comprehensive review of the development of battery remaining useful lifetime (RUL) prognostic techniques. Upcoming challenges and future research directions are identified and discussed.
Therefore, precisely predicting the cycle life of LIBs can help industries optimize battery usage, replacement schedules, reducing unnecessary replacements and associated costs. In addition, researchers can evaluate the quality of batteries in advance which enables them to identify potential issues and optimize battery design. [5, 6]
In addition, for applications such as electric vehicles and large-scale energy storage systems, this timely life prediction can optimize the efficiency of the battery and extend its service life.
Accurate predictions of the remaining battery lifetime at different operating conditions are essential for the battery management system to avoid potentially dangerous battery failures and guarantee reliable and efficient operation. The remaining battery lifetime information is also critical for battery second-life applications.
Currently, model-based prediction and data-driven prediction are the two most commonly used methods for Li battery life prediction 4, 5. Model-based prediction often requires the construction of mathematical or empirical models based on the analysis of the relevant physicochemical reactions within the battery 6.
