Energy Efficient Manufacture of Beta Alumina Solid Electrolytes Using Microwave Assist Technology(23602)
The sodium based battery is fast becoming the energy storage system of choice, due to its high efficiency, long life, and high energy density. The sodium based batteries still have a few areas of improvement before wide-spread usage is embraced. These include sealing of the battery unit, improved performance of the beta alumina solid electrolyte (BASE), and a lower cost. Currently, BASE suffers a tradeoff between ionic conductivity and mechanical strength. Conventional sintering requires long, energy intensive dwell times to reach full density, this long processing time also leads to exaggerated grain growth (which weakens the BASE) and sodium loss (which lowers conductivity).
Ceralink proposes a manufacturing demonstration using Microwave Assist Technology (MAT) to calcine beta alumina powders and sinter the final BASE product. Ceralink will provide the final BASE product and Alfred University will conduct testing of the BASE performance, while a potential customer, Eagle Picher, will also test the product.
The anticipated benefits are an average of 50% energy savings when using the MAT to sinter and calcine the BASE product. Electric energy savings of approximately 75,000 kWh/year, with a cost saving of $111,000 are anticipated. Other benefits include economic development, and decreased greenhouse gas emissions.
