Lithium batteries have the characteristics of high energy density, high rated volt-age, and low self-discharge rate. Improper use can cause accidents such as spontaneous combustion and explosion. The key to ensure stable and safe operations of a lithium battery in a system is to quickly and accurately estimate the SOH of the lithium battery.
Shelf life refers to the duration a lithium-ion battery can be stored without significant degradation. The shelf life of a lithium-ion battery in storage varies depending on the storage conditions. It is influenced by factors such as temperature, state of charge, and the specific chemistry of the battery.
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.
