ALIDISSI, a Research Program to Evaluate Electrochemical Impedance Spectroscopy as a SoC and SoH Diagnosis Tool for Li-ion Batteries
Abstract
ALIDISSI is a French research project aiming at evaluating Electrochemical Impedance
Spectroscopy (EIS) as a diagnosis tool for Li-ion batteries to be used in future Hybrid
Electric Vehicles (HEV) and on-grid photovoltaic (PV) systems. This paper describes the
project methodology. A review of ageing mechanisms in lithium-ion batteries is proposed
first to point out the main processes reported in the literature and their related
accelerating factors. The accelerating ageing profiles developed in this project to
accelerate ageing in lithium-ion batteries are described next for both applications.
Preliminary results obtained on 3-electrode prototype pouch cells made with traditional
electrode couple like LiNiCoAlO2/LiC6 and a promising electrode
couple (LiFePO4/Li4Ti5O12) are also presented
in the last part of this work.
