Imagine dusk on the prairie with a clear sky, calm winds, and the setting sun. This tranquil picture doesn’t often evoke thoughts of electrons hurtling toward ions and streaking through orbits. But work is underway to widely convert energy when nature is busy to store for times like this one. Electrical energy storage in batteries and supercapacitors has the potential to make the electric grid more efficient, release wide-scale solar energy from the daytime into the night, and power electric cars for hundreds of miles. Each application has unique requirements. Whether for devices that hold more energy at less weight or deliver energy faster, storage advances rely on discovering underlying science -- principles from the atomic, nano-, and micro-scale up to the device and systems level. At each step, disciplines converge to push materials, techniques, and designs to their limits for energy storage that meets requirements and is safe and long lasting. New work in lithium batteries, supercapacitors, and flow batteries will show the creative efforts across and between fields -- from nano-scale designs that improve multiple electrochemical processes at once to materials that repair failures before they become catastrophic.
