Description

On 11 brand new cylindrical rechargeable Lithium Iron Phosphate batteries, Electrochemical Impedance Spectroscopy (EIS) were measured at SoC 100%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 35%, 30%, 25%, 20%, 15%, 10%, 5%. All of these measures for each battery are repeated for two discharge cycles. Impedance frequencies[ 0.01, 0.02, 0.03, 0.05, 0.08, 0.1, 0.2, 0.3, 0.5, 0.8, 1, 2, 3, 5, 8, 10, 11, 21, 31, 61, 81, 100, 110, 210, 310, 510, 810, 1000 ] Hz used for the all EIS spectrum. The files are organized in directories. There are eleven directories one for each battery, from “ B01” to “ B11”. Each of these directories further contains two directories, “ EIS Measurement” and “Capacity Measurement”. In the first one there are all the test directories, inside each test folder there are the corresponding test comma-separated values (csv) files with all the impedance spectroscopy measurements. In the second folder, on the same level as “ EIS Measurement” there is the battery capacity test also in a csv formatted file.
