Investigating the capability of the reference electrode to accurately detect the onset of Lithium plating in Li-ion battery

Reducing greenhouse gas emissions through the widespread adoption of electric vehicles remains challenging due to the high charging time of today's batteries. Indeed, increasing the charging rate of Li-ion batteries leads to an increased risk of lithium plating: a parasitic reaction that affects the safety and durability of the battery. It is therefore essential to develop a real-time Li plating detection technique compatible with industrial applications i.e., a reference electrode (RE). We propose here to perform X-ray diffraction at several locations in a pouch-cell: close to the RE as well as far away from the RE to investigate the capability of the reference electrode to detect the onset of Li plating accurately.
