Louis Piper is the Professor of Battery Innovation and heads the Electrochemical Materials group in the Energy Directorate at WMG, the University of Warwick. He co-leads the Faraday Institution Degradation and FutureCat Phase II projects that focus on developing next generation cathode chemistries and understanding how to improve capacity retention in state-of-art Ni-rich and phosphate cells. His activities are at the interface between physics, chemistry and engineering, and typically involve employing new capabilities to solve long-standing problems in materials science. His current research focus is on employing novel methods for studying real-format batteries to improve performance by connecting new materials, pilot line cell manufacturing, and advanced characterization methods (e.g. operando x-ray).
