Quantum Batteries Based on Metastable Molecules

Quantum batteries (QB) are still experimental, but their potential to revolutionize energy storage is immense. This work provides a thorough physical explanation and investigation into the possible practical realization of energy storage. The core idea is to use metastable molecules and the rules of forbidden transitions to store energy in the excited state for an extended period. Metastable states are unique because they allow systems to remain in non-equilibrium conditions for extended periods before transitioning to stable states. Metastability also offers protection against dissipation and decoherence; however, its application in QB remains largely unexplored. The potential of the “Pentacene 5b and 5c” molecules has been explored as a practical realization of QB.
