Electrochemical energy storage becomes more and more important in the context of next generation power grid, home storage, electric transportation and well-established applications such as power tools and portable devices. Our research is focused on developing materials and technologies for energy storage in batteries and related devices. A particular focus is on beyond-lithium batteries such as sodium-ion, potassium-ion and dual-ion batteries. Another avenue of our research is in hybrid storage technologies (metal-ion capacitors).
