iPes project aims to provide adequate support to Dr. David Mecerreyes (DM) who is at the stage of consolidating an independent research team. During his scientific career, DM has demonstrated creative thinking and excellent capacity to carry out research and going beyond the state of the art. His meritorious record of research, scientific publications (128 ISI articles, h index = 33), project conception, private sector experience, networking ability (participated in 10 European collaborative projects) and capacity for supervising and coordinating a research team are presented in detail in the initial part of the proposal. He recently moved from the private sector to create a new research group at the University of the Basque Country. He is now in an excellent academic position and research environment to commit and be devoted to an ERC frontier research project. DM’s proposal passed to the second stage in the ERC starting grant call of last year. This year the research project has been re-built taking into account his group directions and the detected weak points of last year’s proposal. This is his last opportunity for participating to the ERC starting-grant call.iPes proposes an innovative research programme at the forefront of polymer chemistry. The proposal goes in depth into the topic of energetic polymers. iPes activities will fully develop the field of polymers for energy storage by using an innovative macromolecular engineering approach generating the ground for future innovations. The main S&T goal is to obtain new polymeric materials, to get an insight into their unique electronic properties, to model the new energetic polymers and to investigate their application in innovative battery prototypes. These technologies are currently dominated by inorganic electrode materials. iPes aims at bringing polymer chemistry to a next level and developing basic knowledge about innovative polymeric materials which may open up new opportunities for Energy Storage.
