Room-Temperature Micro-SMES via Acoustically Stabilized YHf2H24 Multilayer Stacks: A Solid-State Infinite Storage Solution

The era of chemical energy storage, plagued by degradation, finite cycles, and sluggish charging, is poised for disruption by physical alternatives that promise eternal performance. Here, we introduce a room-temperature micro-superconducting magnetic energy storage (Micro-SMES) device—termed the Pirolo Power Stack—leveraging acoustically stabilized YHf2H24 nanoribbons to achieve a volumetric energy density of 331.08 Wh/L—competitive with lithium-ion batteries—while enabling sub-second charging and infinite cycle life. Stabilized at 298 K via a 45 GHz phonon drive, this solid-state architecture confines magnetic fields up to 17.95 T within a compact 10.0 mm diameter x 0.5 mm thick multilayer stack, storing 46.80 J per cell. Uniquely, the device achieves zero-energy standby through sympathetic energy harvesting from ambient mmWave radiation (Wi-Fi 7/6G) and implements anti-fragile safety via a regenerative piezo-shunt that strengthens superconductivity under stress through Kapitza-like dynamical stabilization—fault energy is channeled into phonon pumping rather than dissipated as heat, reinforcing the order parameter with sub-microsecond response times. Operating as an autonomous "black box" without external battery management systems, this innovation heralds a paradigm shift toward indestructible, instantaneous power for portable electronics, electric vehicles, and grid-scale applications.
