The research team tested 92 commercial lithium-ion batteries for more than two years across the discharge profiles. In the end, the more realistically the profiles reflected actual driving behavior, the higher EV life expectancy climbed. Several factors contribute to the unexpected longevity, the study finds.
This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.
By fitting partial data and reasonably using formula extrapolation, it is possible to predict the lifespan of lithium batteries in the early stages. Common formulas include polynomial models [79, 80], double-exponential models [81, 82], logarithmic models , and Gaussian models . Some common empirical models are listed in Table 2.
Aging characteristics of lithium-ion batteries throughout full lifecycles. During the initial stages of use, LIBs often demonstrate excellent performance. The formation of the SEI layer on the anode surface is ongoing, leading to the consumption of some lithium ions.
A major challenge in the field of early life prediction of lithium-ion batteries is the lack of standardized test protocols. Different research teams and laboratories adopt various methods and conditions, complicating the comparison and comprehensive analysis of data.
