Energy and energy storage are essential to modern daily life. These includes harvesting energies, enabling renewables, supporting the grid, powering up portable electronics and enabling e-mobility. The ENE department houses a group of dedicated, experienced and highly talented scientists and technical staff with interdisciplinary expertise in energy and energy storage related technologies. We address fundamental issues of materials and electrochemical interactions associated with lithium and beyond-lithium batteries. We optimize next generation, high-energy Lithium-ion batteries that incorporate new battery materials and structures. We develop next generation battery pack and management system with data-driven testing and analytics. We also innovate to take care end-of-life battery through remanufacturing, repurposing and recycling technologies.
