| contents | Quantum batteries (QBs) -- quantum devices governed by the principles of quantum mechanics -- hold great promise for next-generation energy storage. However, most existing research efforts focus on atomic or molecular systems featuring low-energy and short-lived energy levels, leaving the exploitation of high-energy, ultra-stable nuclear energy levels for energy storage as a critical unaddressed challenge. Here, we propose an innovative design of referred to as nuclear isomer quantum batteries (NIQBs), whose energy storage unit is typically composed of two-level and three-level nuclei incorporating nuclear isomers. The charging dynamics is driven by the interaction between the nuclear system and x-ray free electron laser (XFEL). Compared to QBs based on atomic systems, NIQBs deliver substantial performance enhancements, with stored energy and average charging power enhanced by factors of $10^{1}$--$10^{6}$ and $10^{6}$--$10^{11}$, respectively, and a markedly extended lifetime range spanning from microseconds to $10^5$ years. Notably, the vast majority of NIQBs enable complete energy extraction as their excited-state lifetimes exceed the laser-nuclear interaction time, rendering spontaneous emission negligible. The proposed NIQBs framework is compatible with diverse nuclear systems, enabling tailored nucleus selection for varied operating conditions. Our results provide a feasible pathway toward realizing high-performance QBs with superior energy-storage efficiency. |
