Raphaële Clément investigates how the internal structure of materials influences the performance of rechargeable batteries. Her research focuses on understanding why some battery materials are more efficient, durable, or safe than others. Together with her team, Clément studies these materials down to the level of individual atoms, even as the batteries charge and discharge. By using advanced analytical techniques, she reveals minute structural and chemical changes that determine how well a battery performs. The ultimate goal of her work is to develop new materials that deliver higher performance while being safer and more sustainable.
