Research
My research aims to understand and mitigate ageing and performance limitations in lithium-ion batteries by elucidating electrochemical and chemical processes at electrolyte–electrode interfaces. It focuses on how interfacial reactions govern calendar life, cycle life, and rate capability, with the goal of enabling durable, high-performance, and sustainable battery technologies.
A central aspect of my work is the development and application of advanced electrochemical diagnostics to study battery degradation and interphase formation in both laboratory and commercial cells under realistic operating conditions. These include operando gas analysis techniques to investigate oxidative and reductive electrolyte reactions at the positive and negative electrodes.
By combining electrochemical impedance spectroscopy (EIS) with complementary physicochemical methods to analyze lithium-ion transport in porous electrodes, interfacial electrolyte–electrode reactivity is linked to transport limitations.
Overall, my research integrates operando diagnostics, electrochemical analysis, and materials characterization to deliver a mechanistic understanding of battery degradation and to guide the design of longer-lasting and safer lithium-ion cells.
