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.
