This work presents the concept and experimental basis of the Ψ-Cell, a solid-state battery that stores and releases energy through coherent pressure fields within graphene, instead of chemical reactions. Laboratory tests confirm reversible charge–discharge behavior driven by internal pressure coupling in multilayer graphene structures.

The Ψ-Cell operates silently, without degradation, heat, or chemical residues, offering a scalable path from sensor-level energy units to domestic modules (1–50 W). It represents a practical translation of pressure-field physics into a new class of sustainable, recyclable energy devices
