Looking for a New Paradigm for Next‐Generation Batteries

limited primarily by charge and mass transfer along their surfaces, across interfaces, and/or throughout porous electrodes.To meet the requirements for many practical applications, battery systems will require advanced electrodes with well-controlled nanoarchitectures and chemistries tailored for dramatic enhancements in energy and power density, catalytic activity, effi ciency, durability, and operational life.This special issue of Advanced Energy Materials is therefore a timely opportunity to highlight some of the exciting recent advances in R&D of batteries and their anode and cathode materials by renowned international authors and leading industries.In this special issue, newly emerging batteries, such as Na-ion batteries, lithium-air (oxygen) batteries, fl ow capacitors, and Li-redox fl ow batteries are reviewed to illustrate both the breadth of the high quality work and the important roles that fundamental research and practical application play in the development of sustainable clean-energy technologies.Anode and cathode materials for those batteries are also addressed in this special edition, ranging from porous Si, graphene, and organic materials to catalysts.
