OFFER DESCRIPTION

The electrochemical storage of electrical energy has become a global issue and a major challenge. Li-ion

batteries are considered as the preferred solution to store energy on board of new generation electric and

hybrid vehicles or manage renewable energy in stationary applications. Safe batteries systems still represent

today the weakest link in the development of many energy or power demanding applications. This thesis

aims to understand and model the phenomenon of thermal runaway lithium-ion batteries initiated by an

internal short-circuit, taking into account the influence of technology and aging. It is based on previous

IFPEN works that have developed a methodology to model the thermal runaway of fresh and aged Li-ion

batteries at cell level. This thesis will extend the IFPEN models by integrating the reaction mechanism

related to the internal short-circuit relying on an adapted experimental methodology, which should be able to

trigger internal short-circuit in a controllable and repeatable manner. This thesis project offers an original

approach combining experimental and modeling studies, where the experimental part will serve the

phenomenological understanding and the extension of the model. In addition, abuse tests will be conducted

to ensure the calibration and validation of the developed model. The direction of the thesis will be supervised

by the LRCS, a French major laboratory in the field of electrochemical energy storage.
