This book reviews the structure and composition of Prussian Blue materials. It presents the state-of-the-art of their application to metal-ion batteries, highlighting the benefits derived from the integration of electrochemical energy storage with clean energies. It concludes with future perspectives including prototyping and large-scale production.

María José Piernas Muñoz received her Bachelor of Chemistry on 2011 and her Master's Degree in Fine and Molecular Chemistry at the University of Murcia (Murcia, Spain). Currently, she is a PhD student at the CIC Energigune (Álava Technology Park, Spain) and her research is focused on the searching and development of new materials for energy storage both for lithium and sodium ion batteries.

Elizabeth Castillo Martinez received her D. Phil. degree in Chemistry from the University Complutense of Madrid in 2008. She is an Associate Researcher at CIC-Energigune investigating materials for Lithium ion batteries, including intercalation and conversion materials, redox flow batteries as well as Na-ion batteries with special interest on -N=C- related materials (Prussian Blue, Schiff bases and Carbodiimides).
