Single Atom/Molecule Quantum Energy Storage

This contributed volume explores the emerging concept of quantum batteries, a new class of energy storage devices that rely on the principles of quantum physics rather than conventional electrochemistry. It introduces readers to the foundational ideas of quantum thermodynamics and quantum superposition, explaining how isolated quantum systems such as single atoms or molecules can store energy within their internal quantum states. The book describes how these quantum batteries differ from traditional ones by offering the potential for dramatically faster charging and enhanced power at the nanoscale. It guides graduate-level readers through the steps toward realizing the first atomic-scale and single-molecule quantum battery unit cells, positioning the technology within the broader landscape of rapidly advancing quantum computing, sensing, communication, and cryptography. Overall, it serves as a timely roadmap for students, researchers, and professionals who aim to understand, design, and eventually construct the next generation of quantum energy storage devices.
