Storage of Electrical Energy

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes an electrochemical energy storage device (battery) that uses two separated half-cells: one containing a positive electrode in contact with a solution of iron hexacyanoferrate ([Fe(CN)6]3-) and the other a negative electrode exposed to hydrogen gas. The two half-cells are separated by an ion-conductive membrane, allowing charge transfer during charging and discharging cycles. The system is cost-effective, durable, and primarily utilizes abundant, inexpensive raw materials like iron, carbon, water, and nitrogen.

Use CasesContent extracted from patent full text and abstract with AI.

• Grid energy storage for renewable energy integration (e.g., solar and wind farms)
• Backup power systems for critical infrastructure (e.g., hospitals, data centers)
• Industrial energy storage to level load and reduce peak demand charges
• Home or commercial battery storage solutions
• Off-grid energy storage for remote or disaster-prone areas

BenefitsContent extracted from patent full text and abstract with AI.

• Long operational life due to the stable chemistry of the cell materials
• Low material costs, as it uses widely available and inexpensive resources
• Environmentally friendly, relying on non-toxic and abundant elements
• Can be constructed using robust, low-cost electrode materials like steel
• Resistant to typical battery degradation mechanisms like cross-contamination, as phase separation can recover individual substances
• High cycling efficiency and rechargeability
• Safe operation, especially compared to systems using volatile or flammable electrolytes
