Rechargeable All-Water Atomic Battery

Resumen de: US2025246614A1

A rechargeable electrochemical system is disclosed that operates using ultra-pure water and a preconditioned electrode without added salts, acids, bases, or catalysts. The electrode is infused with reactive hydrogen species, such as atomic hydrogen, through methods including electrolysis, thermal exposure, or ambient-compatible water jet impact. Upon immersion in ultra-pure water and pairing with a second electrode, the infused electrode induces a spontaneous electrochemical potential. The water, initially non-conductive, becomes weakly alkaline and functions as an electrolyte. The system generates measurable voltage and current under ambient conditions. After discharge, the infused electrode can be restored by reapplying the hydrogen-infusion process or an external potential, enabling repeated charge-discharge cycles. Experimental validation shows consistent electrochemical behavior and power output sufficient for common electronic components. This system offers a scalable, environmentally compatible alternative to conventional batteries and hydrogen energy systems, enabling novel electrochemical operation under benign conditions and opening pathways in low-energy nuclear processes.
