Experimental data of three lithium-ion batteries under galvanostatic discharge tests at different rates and temperatures of operation
Hardware: • Arbin Instruments LBT21024 and Arbin measurement system; • IncuMax IC-500R thermal chamber Arbin Instruments LBT21024; • T-type thermocouple sensor, Omega. Software: • MITS Pro software and Data Watcher. The Arbin system supplies the user-defined current to the battery and measures voltage and surface temperature responses. Once the battery is fully charged (after the CC-CV protocol), a galvanostatic discharge profile is applied until the voltage cutoff limit is reached (2.5V for NCA and NMC, 2V for LFP chemistry). The type-T thermocouples are placed at the center location and measure the battery skin temperature. The ambient temperature is controlled by the user via the thermal chamber.
