Inspired by this, various research groups have attempted to employ different ML models and features to predict the cycle life of commercial LIBs. [18, 19] The use of various battery cell systems and the application of different ML methods display the effectiveness of cycle life prediction.
Based on these issues, much effort have been put to improve the utilization efficiency of lithium such as mitigating the side reactions, guiding the uniform lithium deposition, and increasing the adhesion between electrolyte and electrode. In this review, strategies for high utilization efficiency of lithium are presented.
To evaluate the deterioration of lithium-ion battery health, the stochastic process is better characterized. The algorithm still has a problem in generating correct findings when taking into account the effect of random current, time-varying temperatures, and self-discharge characteristics. 3.8.4. Others technique
In previous work, Sayavong and his colleagues discovered that the SEI matrix begins to dissolve when the battery is idle. Based on that finding, the Stanford team decided to see what would happen if the battery was allowed to rest while discharged.
Currently, research on the echelon utilization of retired power LIBs mainly focuses on classification and recombination methods to reduce the intra-group inconsistency of LIBs, and few studies focus on the chemical reactions inside the batteries.
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]
