Battery_Acoustic_emission_data

After cyclic aging, the batteries, along with fresh ones, were discharged at rates of 1C and 0.5C. The main parameters involved in the dataset include battery current, battery voltage, amplitude of acoustic emission waveform signals, event time interval, and waveform time interval.

Among these, the two feature parameters, event time interval and waveform time interval, are calculated. All battery groups generated pulse-type acoustic emission signals during the 1C and 0.5C charging and discharging processes. The acoustic emission waveform signals exhibited dual-waveform characteristics throughout the entire charging and discharging cycles, with both the waveform time interval and signal time interval following a pattern of rapid decline initially, followed by a stable decline.
