This article presents a classification method that utilizes impedance spectrum features and an enhanced K-means algorithm for Lithium-ion batteries. Additionally, a parameter identification method for the fractional order model is proposed, which is based on the flow direction algorithm (FDA).
This research introduces a battery classification approach that leverages impedance spectrum features and an improved K -means algorithm. The methodology begins with conducting an impedance spectroscopy test on lithium-ion batteries to obtain their electrochemical impedance spectra at various frequencies.
Lithium Battery – The term “lithium battery” refers to a family of batteries with different chemistries, comprising many types of cathodes and electrolytes. For the purposes of the DGR they are separated into: Lithium metal batteries. Are generally primary (non-rechargeable) batteries that have lithium metal or lithium compounds as an anode.
Battery data description This study considers three types of commercial LIBs widely applied in electric vehicles and grid-scale energy storage systems in terms of materials, i.e., the lithium-iron phosphate (LFP) battery, lithium cobalt oxide (LCO) battery, and Li (NiMnCo)O2 (NMC) battery.
Therefore, the early-cycle range of first 20 cycles is the more suitable option that could provide accurate and rapid battery classification. In subsequent analysis, battery data from the first 20 cycles is utilized unless otherwise stated.
A classification accuracy of 96.6% can be achieved using the first-20-cycle battery data and an accuracy of 92.1% can be achieved using only the first-5-cycle battery data. The remainder of this paper is organized as follows. In Section 2, specifications of different types of LIBs studied in this work are introduced.

This paper discusses the development history, working principle, classification and practical application of lithium electronic batteries in real life.
For lithium-ion batteries, silicate-based cathodes, such as lithium iron silicate (Li 2 FeSiO 4) and lithium manganese silicate (Li 2 MnSiO 4), provide important benefits. They are safer than conventional cobalt-based cathodes because of their large theoretical capacities (330 mAh/g for Li 2 FeSiO 4 ) and exceptional thermal stability, which lowers the chance of overheating.
