Impedance-based forecasting of lithium-ion battery performance amid uneven usage

HIGHLIGHTS

  • who: Penelope K. Jones from the (UNIVERSITY) have published the paper: Impedance-based forecasting of lithium-ion battery performance amid uneven usage, in the Journal: (JOURNAL) of 15/Nov/2021
  • what: To address this challenge, here the authors propose a combination of electrochemical impedance spectroscopy measurements with probabilistic machine_learning methods. Making use of a dataset of 88 commercial lithium-ion coin cells generated via multistage charging and discharging (with currents randomly changed between cycles), the authors show that future discharge capacities can be predicted with calibrated uncertainties, given the future cycling protocol and a single . . .
